3 CEMENTITIOUS GROUTS FIVE STAR GROUT A standard cementitious grout developed for applications where an economical grout with good flow and strength is required. Five Star Grouts are based on specially selected Portland cements, graded aggregates and admixtures including a special form of carbon. This special formulation produces a grout that conforms to ASTM C827 Early Volume Change of Cementitious Mixtures. Does not contain iron, aluminium or other additives which eliminates any subsequent problems of dimensional instability, corrosion or staining. Five Star Grout is designed primarily as a flowing grout but can also be used at a trowellable or dry pack consistency. It can be applied in thicknesses from 10 to 100mm. Uses: Under stanchion plates and machinery (static loads only). Grouting bearings, precast units, floors etc. Fixing anchor bolts, ballustrades, crash barriers, starter bars. Underpinning. Void filling. FIVE STAR GROUT SP Five Star Grout SP is a special performance, higher flow version of the standard grout. It can be applied in thicknesses from 10 to 50mm. It has superior properties and complies with HA Spec for use in bridge bearings.

9 CHEMICALS FOR FORMWORK ADOTUF CONCRETE SURFACE HARDENER AND DUSTPROOFER The application of Adotuf to an existing cement-bound floor will significantly improve the properties of the floor to render dustproof, oil and grease proof, case hardened, resistant to dilute acids, more durable longer lasting and easier to clean. Surface preparation: Cement bound floors must be sound, clean, dry and free from oils, greases, fats etc. New floors require at least 10 days to thoroughly dry out before treatment. Covering capacity: Depends upon floor but average guide is 8m2 per litre of Adotuf per coat and generally two coats are required for best results. Available in 5, 25 and 210 litre sizes. ADOCURE WW A white, aqueous silicate solution, designed to deposit a layer of firmly bonded, high cohesive strength, minute crystals within the top surface of the concrete to form an integral membrane which fills all surface pores and capillaries to reduce moisture evaporation. Coverage: 5.5m2 per litre. Available in 25 and 210 litre sizes. Water retention tests on Adocure WW treated cubes and control cubes stored for 24 hours at 30 C showed the following results. Adocure WW Treated (%) Control (%) Water retention Water retention Water retention Avg. water retention The moisture retaining properties of the Adocure WW will reduce over the first few weeks after application so that the subsequent application of penetrating treatments will be unaffected. ADOCURE WWT Fugitive dye is added to Adocure WW to aid visual identification of areas of application. Available in 25 and 210 litre sizes. 97
