Couplers are fixed, stressing, or moveable. The prinipal dimensions of anhorages and ouplers are given in Annex 2, Annex 3, Annex 4, Annex 5, Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex Designation End anhorage e.g. S A Fixed (F) or stressing (S) Anhorage Designation of the tendon with information on number, ross-setional area, and harateristi tensile strength of prestressing steel strands Coupler e.g. F K Fixed (F), stressing (S) or moveable (B) Coupler anhor head (K or H) Designation of the tendon with information on number, ross-setional area, and harateristi tensile strength of prestressing steel strands Anhorage, FA or SA General Anhorage of prestressing steel strands is ahieved by wedges and anhor heads, see Annex 1, Annex 2, Annex 3, and Annex 7. The anhor heads of the fixed and stressing anhorage are idential. A differentiation is needed for the onstrution works.

10 Page 8, The wedges of inaessible fixed anhors are seured with either a wedge retaining plate or springs and a wedge retaining plate. An alternative is pre-loking eah individual prestressing steel strand with ~ 0.5 F pk and applying a wedge retaining plate. Where F pk... Charateristi value of maximum fore of one single prestressing steel strand Restressable and exhangeable tendon Signifiant to a restressable and exhangeable tendon is the exess length of the prestressing steel strands, see Annex 1. The extent of the exess length depends on the jak used for restressing or releasing. The protrusions of the prestressing steel strands require a permanent orrosion protetion and an adapted ap Fixed and stressing oupler General Anhorage of prestressing steel strands is ahieved by wedges and oupler anhor heads, see Annex 1, Annex 2, Annex 4, Annex 5, and Annex Single plane oupler, FK or SK The oupling is ahieved by means of a oupler anhor head K. The prestressing steel strands of the first onstrution stage are anhored by means of wedges in mahined ones, drilled in parallel. The arrangement of the ones of the first onstrution stage is idential to that of the anhor head of a fixed or stressing anhorage. The prestressing steel strands of the seond onstrution stage are anhored in a irle around the ones of the first onstrution stage by means of wedges in mahined ones, drilled at an inlination of 7. The wedges for the seond onstrution stage are seured by means of holding springs and a over plate Sleeve oupler, FH or SH The oupler anhor head H is of the same basi geometry as the anhor head of the fixed or stressing anhorage. Compared to the anhor head of the fixed or stressing anhorage, the oupler anhor head H is higher and provide an external thread for the oupler sleeve. The wedges for the seond onstrution stage are seured by means of a wedge retaining plate. The onnetion between the oupler anhor heads H of the first and seond onstrution stages is ahieved by means of a oupler sleeve Moveable oupler, BK or BH Anhorage of prestressing steel strands is ahieved by wedges and oupler anhor heads, see Annex 1, Annex 2, Annex 4, Annex 5, and Annex 7. The moveable oupler is either a single plane oupler or a sleeve oupler in a oupler sheathing made of steel or plasti. Length and position of the oupler sheathing are for the expeted elongation displaement, see Clause The oupler anhor heads and the oupler sleeve of the moveable oupler are idential to the oupler anhor heads and the oupler sleeve of the fixed or stressing oupler. The wedges for the first onstrution stage are seured by means of a wedge retaining plate and the wedges of the seond onstrution stage are seured by wedge retaining plate or holding springs and over plate. A 100 mm long and at least 3.5 mm thik PE-HD insert is installed at the deviating point at the end of the trumpet. The insert is not required for plasti trumpets where the duts are slipped over the plasti trumpet.

11 Page 9, Layout of the anhorage reess All bearing trumplates, anhor heads, and oupler anhor heads are plaed perpendiular to the axis of the tendon, see Annex 17. The dimensions of the anhorage reess are adapted to the prestressing jaks used. The ETA holder saves for referene information on the minimum dimensions of the anhorage reess. The formwork for the anhorage reess should be slightly onial for ease of removal. In ase of an internal anhorage fully embedded in onrete, the reess is designed so as to permit a reinfored onrete over with the required dimensions and in any ase with a thikness of at least 20 mm. In ase of an exposed anhorage, see Annex 17, onrete over on anhorage and square plate is not required. However, the exposed surfaes of square plate and steel ap are provided with orrosion protetion. 1.3 Designation and range of the tendons Designation Tendon e.g Internal PT Number of prestressing steel strands (02 to 61) Prestressing steel strand Cross-setional area of prestressing steel strands (140 or 150 mm 2 ) Charateristi tensile strength of the prestressing steel strands The tendons omprise 01 to 61 tensile elements, 7-wire prestressing steel strands aording to Annex Range General Prestressing and overstressing fores are given in the orresponding standards and regulations in fore at the plae of use. The maximum prestressing and overstressing fores aording to Euroode 2 are listed in Annex 16. The tendons onsist of 01, 02, 03, 04, 05, 06, 07, 08, 09, 12, 13, 15, 16, 19, 22, 24, 25, 27, 31, 37, 42, 43, 48, 55 or 61 prestressing steel strands. By omitting prestressing steel strands in the anhorages and ouplers in a radially symmetrial way, also tendons with numbers of prestressing steel strands lying between the numbers given above an be installed. Any unneessary hole either remains undrilled or is provided with a short piee of prestressing steel strand and a wedge is inserted. For oupler anhor head K the ones of the outer pith irle, seond onstrution stage, may be equally redistributed if prestressing steel strands are omitted. However, the overall dimensions of the oupler anhor head K remain unhanged. With regard to dimensions and reinforement, anhorages and ouplers with omitted prestressing steel strands remain unhanged ompared to anhorages and ouplers with a full number of prestressing steel strands n wire prestressing steel strand Nominal diameter mm Nominal ross-setional area mm 2 Maximum harateristi tensile strength MPa Annex 8 lists the available tendon range for n

13 Page 11, Degree of filling The degree of filling, f, for a irular dut is generally between 0.35 and However, the smaller values of degree of filling, 0.35 to 0.40, are used for long tendons or if the tensile elements are installed after onreting. The minimum radius of urvature an be defined with the equation given in Clause 1.9. Typial degrees of filling, f, and orresponding minimum radii of urvature, R min, are given in Annex 10, Annex 11, and Annex 12. The degree of filling is defined as ross-setional area of prestressing steel f= ross-setional area of inner diameter of sheath Cirular steel strip sheath Steel strip sheath in onformity with EN 523 2, with minimum wall thiknesses aording to Table 2, is used. For diameters exeeding EN 523 the requirements are met analogous. The degree of filling, f, is aording to Clause and the minimum radius of urvature to Clause 1.9. Annex 11 and Annex 12 give internal dut diameters and minimum radii of urvature in whih p R, max has been set to 200 kn/m and 140 kn/m respetively. Smaller radii of urvature are aeptable aording to the respetive standards and regulations in fore at the plae of use Flat orrugated steel dut For a tendon with 2, 3, 4, or 5 prestressing steel strands, a flat dut may be used, whereas EN 523 applies aordingly. Inner dimensions of the dut and the minimum radii of urvature are defined in Annex 10. Annex 10 gives minor and major internal flat dut diameters and minimum radii of urvature, both minor and major, in whih p R, max has been set to 200 kn/m and 140 kn/m respetively. Smaller radii of urvature are aeptable aording to the respetive standards and regulations in fore at the plae of use Pre-bent smooth irular steel dut If permitted at the plae of use, a smooth steel dut aording to EN 10255, EN , EN , EN or EN is used. The degree of filling, f, onforms to Clause and the minimum radius of urvature to Clause 1.9.The dut is pre-bent and free of any kinks. The minimum radii of urvature, R min, is aording to Clause 1.9. The minimum wall thikness of the steel dut meets the speifiation of Table Frition losses For alulation of loss of prestressing fore due to frition, Coulomb's law applies.

The opposite end is onneted to the square plate or oupler anhor head K Coupler anhor head The oupler anhor head K, see Annex 4, for the single plane oupler is made of steel and provides in the inner part, for anhorage of the prestressing steel strands of the first onstrution stage, the same arrangement of holes as the anhor head for the stressing or fixed anhorage. In the outer pith irle there is an arrangement of holes with an inlination of 7 to aommodate the prestressing steel strands of the seond onstrution stage. At the bak of oupler anhor head K there is a step for ease of entring the oupler anhor head on the bearing trumplate. Wedge retaining plate KS, see Annex 7, and springs K, see Annex 7, with over plate K, see Annex 4, are fastened by means of additional threaded bores. The oupler anhor heads H1 or H2 for the sleeve oupler are made of steel and have the same basi geometry as the anhor head of the stressing or fixed anhorage, see Annex 2 and Annex 5. Compared to the anhor head of the stressing and fixed anhorage, the oupler anhor head H is higher and provide an external thread for the oupler sleeve. At the bak of the oupler anhor head H1 and H2 there is a step for ease of entring the oupler anhor head on the bearing trumplate. Wedge retaining plate KS, see Annex 7, is fastened by means of additional threaded bores. The oupler sleeve H is a steel tube, see Annex 2 and Annex 5, with an inner thread and is provided with ventilation holes. Ring ushions, see Annex 5, are inserted in oupler anhor head H Ring wedge The ring wedge, see Annex 7, is in three piees. Two different ring wedges are used. Ring wedge H in three piees, fitted with spring ring Ring wedge F in three piees, without spring ring or fitted with spring ring Within one anhorage or oupler only one of these ring wedges is used. The wedges of an inaessible fixed anhorage are seured with either a wedge retaining plate or springs and a wedge retaining plate. An alternative is pre-loking eah individual prestressing steel strand with ~ 0.5 F pk and applying a wedge retaining plate as per Clause In ouplers the wedges are seured with wedge retaining plate and over plate Helix and additional reinforement Helix and additional reinforement are made of ribbed reinforing steel. The end of the helix on the anhorage side is welded to the following turn. The helix is plaed in the tendon axis. Dimensions of helix and additional reinforement onforms to the values speified in Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex 26, see also Clause If required for a speifi projet design, the reinforement given in Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex 26 may be modified in aordane with the respetive regulations in fore at the plae of use as well as with the relevant approval of the loal authority and of the ETA holder to provide equivalent performane Protetion ap The protetion ap is made of steel or plasti. It is provided with air vents and fastened with srews or threaded rods Material speifiations Annex 15 lists the material standards or speifiations of the omponents.

19 Page 17, 1.13 Permanent orrosion protetion In the ourse of preparing the European Tehnial Assessment no harateristi has been assessed for omponents and materials of the orrosion protetion system. In exeution, all omponents and materials are seleted aording to the standards and regulations in fore at the plae of use. Corrosion protetion of the bonded tendon is provided by ompletely filling dut, anhorage, and oupler with grout aording to EN 447, speial grout aording to EAD , or readymixed grout with an adequate omposition aording to standards and regulations in fore at the plae of use. To protet an unbonded tendons from orrosion, duts, ouplers, and anhorages are ompletely filled with orrosion protetion filling material as appliable at the plae of use. Appliable orrosion protetion filling materials are grease, wax, or an equivalent soft material. Atively irulating dry air allows for orrosion protetion of a tendon as appliable at the plae of use. In ase of an anhorage fully embedded in onrete, the reess is designed as to permit a reinfored onrete over with the required dimensions and in any ase with a thikness of at least 20 mm. With an exposed anhorage or with an anhorage with insuffiiently thik onrete over, the surfaes of square plate and steel ap are provided with orrosion protetion. 2 Speifiation of the intended uses in aordane with the appliable European Assessment Doument (hereinafter EAD) 2.1 Intended uses The BBR VT with 01 to 61 Strands is intended to be used for the prestressing of strutures. The speifi intended uses are listed in Table 8. Table 8 Intended uses Line Use ategory Use ategories aording to tendon onfiguration and material of struture 1 Internal bonded tendon for onrete and omposite strutures 2 Internal unbonded tendon for onrete and omposite strutures Optional use ategory Internal tendon for ryogeni appliations with anhorage outside the possible ryogeni 3 zone 2.2 Assumptions General Conerning produt pakaging, transport, storage, maintenane, replaement, and repair it is the responsibility of the manufaturer to undertake the appropriate measures and to advise his lients on transport, storage, maintenane, replaement, and repair of the produt as he onsiders neessary.

20 Page 18, Pakaging, transport and storage Advie on pakaging, transport, and storage inludes. During transport of prefabriated tendons, a minimum diameter of urvature of 1.65 m for tendons up to 1206, 1.80 m for tendons up to 3106, 2.00 m for tendons larger than 3106, of prestressing steel strand is observed. Temporary protetion of prestressing steel and omponents in order to prevent orrosion during transport from prodution site to job site Transportation, storage and handling of prestressing steel and other omponents in a manner as to avoid damage by mehanial or hemial impat Protetion of prestressing steel and other omponents from moisture Keeping tensile elements separate from areas where welding operations are performed Design General It is the responsibility of the ETA holder to ensure that all neessary information on design and installation is submitted to those responsible for the design and exeution of the strutures exeuted with "BBR VT with 01 to 61 Strands". Design of the struture permits orret installation and stressing of the tendons. The reinforement in the anhorage zone permits orret plaing and ompating of onrete Fixed and stressing oupler The prestressing fore at the seond onstrution stage may not be greater than that at the first onstrution stage, neither during onstrution, nor in the final state, nor due to any load ombination Anhorage Reess Clearane is required for handling of the prestressing jak and for stressing. The dimensions of the anhorage reess are adapted to the prestressing jak used. The ETA holder saves for referene information on the minimum dimensions of the anhorage reesses and appropriate learane behind the anhorage. The anhorage reess is designed with suh dimensions as to ensure the required onrete over and at least 20 mm at the protetion ap in steel in the final state. In ase of exposed anhorages, onrete over on anhorage and square plate is not required. However, the exposed surfae of square plate and steel ap is provided with orrosion protetion Maximum prestressing fores Prestressing and overstressing fores are speified in the respetive standards and regulations in fore at the plae of use. Annex 16 lists the maximum possible prestressing and overstressing fores aording to Euroode Centre spaing, edge distane, and reinforement in the anhorage zone Centre spaing, edge distane, helix, and additional reinforement given in Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex 26 are adopted, see Clause 1.8. Verifiation of transfer of prestressing fores to strutural onrete is not required if entre spaing and edge distane of anhorages and ouplers as well as grade and dimensions of

21 Page 19, additional reinforement, see Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex 26, are onformed to. In the ase of grouped anhorages, the additional reinforement of the individual anhorages an be ombined, provided appropriate anhorage is ensured. However, number, ross-setional area and position with respet to the square plates remain unhanged. The reinforement of the struture is not employed as additional reinforement. Reinforement exeeding the required reinforement of the struture may be used as additional reinforement, provided appropriate plaing is possible. The fores outside the area of the additional reinforement are verified and, if neessary, dealt with by appropriate reinforement. If required for a speifi projet design, the reinforement given in Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex 25, and Annex 26 may be modified in aordane with the respetive regulations in fore at the plae of use as well as with the relevant approval of the loal authority and of the ETA holder to provide equivalent performane Tendons in masonry strutures load transfer to the struture Post-tensioning kits are primarily used in strutures made of onrete. They an, however, be used with other strutural materials, e.g. in masonry strutures. However, there is no partiular assessment in EAD for these appliations. Hene, load transfer of stressing fore from the anhorage to masonry strutures is via onrete or steel members, designed aording to the European Tehnial Assessment, espeially aording to the Clauses 1.8, 1.10, , and , or aording to Euroode 3, respetively. The onrete or steel members have dimensions as to permit a fore of 1.1 F pk being transferred into the masonry. The verifiation is aording to Euroode 6 as well as to the respetive standards and regulations in fore at the plae of use Installation General It is assumed that the produt will be installed aording to the manufaturer s instrutions or in absene of suh instrutions aording to the usual pratie of the building professionals. Assembly and installation of tendons is only arried out by qualified PT speialist ompanies with the required resoures and experiene in the use of multi strand internal post-tensioning systems, see CWA The respetive standards and regulations in fore at the plae of use are onsidered. The ompany's PT site manager has a ertifiate, stating that she or he has been trained by the ETA holder and that she or he possesses the neessary qualifiations and experiene with the BBR VT with 01 to 61 Strands. The sequene of work steps for installation of anhorage, fixed and moveable oupler is desribed in Annex 28 and Annex 29. The tendons may be manufatured on site or in the fatory, i.e. prefabriated tendons. The tendons are arefully handled during prodution, transport, storage, and installation. To avoid onfusion on eah site only prestressing steel strands with one nominal diameter are used. Square plate, anhor head, and oupler anhor head are plaed perpendiular to the tendon s axis, see Annex 17. Couplers are situated in a straight tendon setion. At the anhorages and ouplers the tendon layout provides a straight setion over a length of at least 250 mm beyond the end of the trumpet. In ase of tendons with a minimum or redued radius of urvature after the trumpet, the following minimum straight lengths after the end of trumpet are reommended. Degree of filling 0.35 f 0.50, minimum straight length = 5 d i 250 mm Degree of filling 0.25 f 0.30, minimum straight length = 8 d i 400 mm

22 Page 20, Where f Degree of filling d i... mm... Nominal inner diameter of dut Before plaing the onrete a final hek of the installed tendon or dut is arried out. In ase of the single plane oupler K, the prestressing steel strands are provided with markers to be able to hek the depth of engagement. In the ase of a moveable oupler it is ensured by means of the orresponding position and length of the oupler sheath, that in the area of the oupler sheath and orresponding trumpet area a displaement of the moveable oupler of at least 1.15 l + 30 mm is possible without any hindrane, where l is the maximum expeted displaement of the oupler at stressing Stressing operation With a mean onrete ompressive strength in the anhorage zone aording to the values laid down in Annex 18, Annex 19, Annex 20, Annex 21, Annex 22, Annex 23, Annex 24, Annex25, and Annex 26 full prestressing may be applied. Stressing and, if appliable, wedging is arried out using a suitable prestressing jak. The wedging fore orresponds to approximately 25 kn per wedge. Elongation and prestressing fores are ontinuously heked during the stressing operation. The results of the stressing operation are reorded and the measured elongations ompared with the prior alulated values. After releasing the prestressing fore from the prestressing jak, the tendon is pulled in and redues the elongation by the amount of slip at the anhor head of the stressing anhorage. Information on the prestressing equipment has been submitted to Österreihishes Institut für Bautehnik. The ETA holder keeps available information on prestressing jaks and appropriate learane behind the anhorage. The safety-at-work and health protetion regulations shall be omplied with Restressing Restressing of tendons in ombination with release and reuse of wedges is permitted, whereas the wedges bite into a least 15 mm of virgin strand surfae and no wedge bite remains inside the final length of the tendon between anhorages. Tendons with 7-wire prestressing steel strands that remain restressable throughout the working life of the struture. Grease, wax, or an equivalent soft material is used as filling material or irulating dry air is used as orrosion protetion. Moreover, a strand protrusion at the stressing anhor remains with a length ompatible with the prestressing jak used Exhanging tendons Exhange of unbonded tendons is permitted, subjet of aeptane at the pae of use. The speifiations for exhangeable tendons are defined during the design phase. For exhangeable tendons, wax or grease is used as filling material or irulating dry air is used as orrosion protetion. Moreover, a strand protrusion remains at the stressing anhor with a length allowing safe release of the omplete prestressing fore. Stressing and fixed anhorages are aessible and adequate spae is provided behind the anhorages Filling operations Grouting Grout is injeted through the inlet holes until it esapes from the outlet tubes with the same onsisteny. To avoid voids in the hardened grout speial measures are applied for long tendons, tendon paths with distint high points, or inlined tendons. All vents, grouting inlets,

23 Page 21, and protetion aps are sealed immediately after grouting. In ase of ouplers K, the seond stage holes, wedges and springs are heked for leanness before and immediately after grouting the first onstrution stage. The standards observed for ement grouting in prestressing duts are EN 445, EN 446, and EN 447 or the standards and regulations in fore at the plae of use are applied for ready mixed grout Filling with grease, wax, and an equivalent soft material The reommendations of the supplier are relevant for the filling material applied. The filling proess with grease, wax, and an equivalent soft material follows a similar proedure as the one speified for grouting. However, a different filling proedure might be possible if permitted at the plae of use Cirulating dry air Atively irulating dry air allows for orrosion protetion of tendons, provided a permanent monitoring of the drying and irulation system is in plae. This is in general only appliable to strutures of partiular importane. The respetive standards and regulations in fore at the plae of use are observed Filling reords The results of the grouting and filling operation are reorded in detail in filling reords Welding Duts may be welded. The helix may be welded to the square plate to seure its position. After installation of the prestressing steel strands further welding operations may not be arried out on the tendons. In ase of welding operations near tendons, preautionary measures are required to avoid damage to the orrosion protetion system. However, plasti omponents may be welded even after installation of the tendons. 2.3 Assumed working life The European Tehnial Assessment is based on an assumed working life of the BBR VT CONA CMI SP with 01 to 61 Strands of 100 years, provided that the BBR VT with 01 to 61 Strands is subjet to appropriate installation, use, and maintenane, see Clause 2.2. These provisions are based upon the urrent state of the art and the available knowledge and experiene. In normal use onditions, the real working life may be onsiderably longer without major degradation affeting the basi requirements for onstrution works 4. The indiations given as to the working life of the onstrution produt annot be interpreted as a guarantee, neither given by the produt manufaturer or his representative nor by EOTA nor by the Tehnial Assessment Body, but are regarded only as a means for expressing the expeted eonomially reasonable working life of the produt. 4 The real working life of a produt inorporated in a speifi works depends on the environmental onditions to whih that works are subjet, as well as on the partiular onditions of design, exeution, use, and maintenane of that works. Therefore, it annot be exluded that in ertain ases the real working life of the produt may also be shorter than the assumed working life.

57 Page 55, 1) Preparatory work The omponents of the prestressing kit are stored so as to avoid any damage or orrosion. 2) Anhorage reesses Adequate spae to aommodate and to use the prestressing jak is ensured, see also the Clauses and ) Fastening the square plates Four holes are provided to fasten the square plates to the formwork. The helix is either welded to the square plate by means of radial bars, see also Clause , or positioned by fastening it to the existing reinforement. 4) Plaing of the sheaths The sheaths are plaed on supports with spaing aording to Clause 1.6 and minimum radii of urvature aording to Clause 1.9. The sheaths are jointed in a leak-proof way. The sheaths are supported suh that any movement is prevented. The same applies for prefabriated tendons. 5) Installation of tensile elements (prestressing steel) The prestressing steel is pushed or pulled into the sheath before or after onreting of the struture. 6) Installation of the inaessible fixed anhorages After passing the strands through the anhor head, they are anhored individually in the ones by means of ring wedges. After assembling the wedges are seured with springs or a wedge retaining plate. An alternative is pre-loking eah individual strand with ~0.5 F pk and applying a wedge retaining plate. 7) Installation of fixed oupler anhor head 2.BA The funtion of the fixed oupler is to onnet two tendons, whereas the first tendon is stressed before the seond tendon is installed and stressed. The oupling is ahieved by pushing the strands into the already tensioned oupler anhor head K, side 2.BA (outer pith irle), whereby the strands are marked to hek the orret depth of penetration. The oupler anhor head H, 2.BA is assembled with ring wedges and a wedge retaining plate. It is onneted to the already tensioned oupler anhor head H, 1.BA by means of a threaded oupler sleeve. 8) Assembly of movable oupler The movable oupler serves to lengthen unstressed tendons. The axial movement during stressing is ensured by a sheathing box suitable to the expeted elongation at the position of the oupler. The assembly of the oupler anhor head is performed in aordane with Point 7) and Clause The transverse fores at the end of the trumpet are overed by steel defletor rings. 9) Cheking the tendons before onreting Before onreting the struture, fastening and position of the entire tendon are heked and orreted if neessary. The sheaths are heked for any damage. Desription of installation Annex 28

58 Page 56, 10) Assembly of anhor head/oupler anhor head 1.BA After passing the strands through the anhor head, they are anhored individually in the ones by means of ring wedges. The same applies for the oupler anhor head in ase of fixed ouplers in the first onstrution stage. 11) Prestressing At the time of stressing the mean onrete ompressive strength is at least aording to Table 6 and the provisions of Clause Stressing and possible wedging is arried out with a suitable prestressing jak and in aordane with Clause The elongation of the tendon and the prestressing fores is heked and reorded systematially during the stressing operation. Restressing the tendons is allowed in aordane with Clause ) Grouting the tendons The grout is injeted through the inlet holes until it esapes from the outlet tubes with the same onsisteny. All vents and grouting inlets are sealed immediately after grouting, see also Clause Grease or wax are injeted in aordane with Clause and the reommendations of the supplier.
