3 TECHNICAL MANUAL FIRE RESISTANCE levels In , a series of fire tests were de what is now known as AustraLite masry. When calculated to the requirements of AS700:0, Secti 6, they were proven to achieve much higher Fire Resistance Levels (FRLs) than standard ccrete masry units: Structural Adequacy FRL: The Slenderness ratio (S rf ) of a proposed wall is calculated by the formulae in AS700, Clause 6... factoring the wall s spanning height/length, thickness and which edges are restrained. The maximum Srfs for AustraLite are: 60 minutes:.9 Loadbearing 7.8 NON-Loadbearing 90 minutes:. Loadbearing 7.8 NON-Loadbearing 0 minutes: 0.6 Loadbearing 6. NON-Loadbearing 80 minutes: 8. Loadbearing.0 NON-Loadbearing 0 minutes: 7.9 Loadbearing.6 NON-Loadbearing The graphs pages to show the AS700 formulae for each of these cditis. Integrity FRL: The NON-Loadbearing test (EWFA.600) of a 90mm wall with S rf =.8 achieved a 0- minute Integrity FRL. According to AS700, Clause 6.., NON-Loadbearing AustraLite masry with t 90mm and S rf.8 will achieve a 0-minute Integrity FRL. NON-LOADBEARING both ends and base.

LOADBEARING Load both ends and base. Srf=. LOADBEARING e end and base. Srf=. Loadbearing 90mm AustraLite is calculated using the deemed-to-satisfy provisis of Clause 6.. Insulati FRL: AustraLite masry requires material thicknesses of: - 70mm to achieve 60 & 90-minute FRLs - 0mm to achieve a 80-minute FRL and - 80mm to achieve a 0-minute FRL - 0mm to achieve a 0-minute FRL All AustraLite masry units have a material thickness greater than 80mm, which gives them a minimum 0-minute Insulati FRL, calculated as per AS700:0, Clause 6..(b) (ii). The highest FRL requirement is 0-minutes. Austral achieves this by reducing the core size of -0 and 0-0 blocks to give them a material thickness greater than 0mm as per AS700, Clause 6... To distinguish these from the 0-minute rated blocks, their code numbers are -0 and 0-0. The Insulati FRL for each block is shown in the following bar chart. INSULATION FRL (MINUTES) CODE NOs. 0-0; 0-; -0; 0-0; - & 0- -; -8 & -9 when core-filled -6; -9; -76 & -0-0 & ; 0-8; 0-9; 0-8 & 0-9 when core filled / /

5 TECHNICAL MANUAL FIRE RESISTANCE LEVELS How to use the Structural Adequacy Charts: The first set of graphs (pages 6 to ) is for NON-Loadbearing masry. The nd set (pages to 6) is for Loadbearing masry. Page 7 is for partially reinforced masry which increases the maximum S rf to 6. Find the appropriate page with the required FRL: 60, 90, 0, 80 or 0 minutes. Next, find the graph with the same restraint cditis as your proposed wall. Finally, plot the intersecti of your wall s height and length the appropriate graph. The thickness required is represented by those lines clear of the intersecti point. Note: All masry must be designed for Robustness (AS700, Part.6). In some cases, the Robustness requirement overrides the FRL limits. Where this occurs, the pale Robustness graph-line changes to the darker colour of the FRL line. Some walls, particularly those without ends restrained, are governed by other loads (e.g. Vertical, Bending, Robustness, Earthquake etc.) Please check this and any other loads with your engineer). Wall size governed by FRL formulae Robustness line Robustness overrides FRL limits Wall height between supports Intersecti point Wall is too big for 0mm thick. OK for 0mm. 0mm hollow 0mm hollow 90mm hollow Wall length between supports / /

18 AUSTRALITE ACOUSTIC RATINGS This secti describes the measurement of acoustic ratings, the BCA requirements for residential buildings and details of research and development of successful wall systems for Denseweight and Lightweight masry. R w (weighted sound reducti index) R w is a type of average of low to high frequencies, calculated from a wall s sound transmissi losses over 6 frequencies. It is measured in decibels (db). Low frequency sound waves (e.g. from a bass guitar) are large and intrusive. Their sound transmissi loss is below R w (average). At the other end of the scale, high frequency sound waves (e.g. violin, piccolo) are short wave, less intrusive and their sound transmissi loss is above average. A typical sound rating is expressed as R w (-; -). The first figure in the brackets is C which indicates irregular performance in the high frequencies. It is not addressed in the BCA. The secd figure in the brackets is C tr and is essential in BCA requirements for party walls. C tr (low frequency spectrum adaptor) C tr is an indicator of how much lower the wall s performance would be if the noise source was mainly low frequency. C tr is a negative number. The sound rating above of R w db with a C tr of - gives R w + C tr = 0. Party Walls: These walls are described in the BCA, Part F, as walls that separate sole-occupancy units (also known as inter-tenancy walls). This includes townhouses, high-rise home units, three-storey flats, hotels and similar residential buildings. Except for Class 9c buildings (aged care units); party walls require a minimum sound rating of R w + C tr 0. A party wall that separates e sole-occupancy unit s wet area (a bathroom, laundry, kitchen etc.) from a habitable room in another sole-occupancy unit is required to be of disctinuous cstructi. / 8 /

19 TECHNICAL MANUAL ACOUSTIC RATINGS Disctinuous Cstructi: The BCA describes disctinuous cstructi as a wall having a minimum 0mm cavity between separate leaves. See following diagrams for details. Where the separate leaves are both masry, the BCA allows resilient wall ties if required. As they are rarely required, their omissi will not ly save mey but improve the acoustic performance of cavity (double-leaf masry) walls. Disctinuous cstructi is also required where a wall separates a sole-occupancy unit from a plant room or lift shaft. Corridor Walls: Walls that separate a sole-occupancy unit from a plant room, lift shaft, corridor, stair, foyer or similar public area, require a minimum sound rating of R w 0. There is no C tr adjustment. See following diagrams for details. Walls that separate a sole-occupancy unit from a plant room or lift shaft are required to be of disctinuous cstructi: e.g: the independent stud system. Research and Development: In 0, the Natial Acoustic Laboratory tested 0mm thick -0 masry. Test N 8-, with a 6mm independent stud wall system, achieved R w + C tr 0 (the BCA requirement for walls separating home units). This wall also meets the BCA requirement to resist the transmissi of impact-generated sound wherever an inter-tenancy wall separates a wet area (bathroom / laundry / kitchen etc) from a habitable room. These and previous tests provided data for Day Design to form opinis the performance of other types of masry as follows. The -0 masry units achieve the BCA fire rating requirements for low to high-rise home unit walls before adding any lining system. / 9 /

26 AUSTRALITE THERMAL MASS informati Thermal mass (also known as thermal inertia or thermal capacitance) is the ability of a material to retain heat when subjected to a temperature differential. Denseweight ccrete has high thermal mass. If a building with high thermal mass is subject to a heating and cooling cycle that crosses the comfort ze, the material with high thermal mass will maintain its heat energy for an extended period. In practical terms, in summer a building with dense ccrete floors and walls will remain relatively cool during the day time, while in winter the same building will remain relatively warm. PROPERTIES OF CONCRETE MASONRY Ccrete masry has moderate thermal insulati properties (ctrolling the passage of applied heat out of the building in winter or atmospheric heat into the building in summer). It has good thermal mass (slowly releasing stored heat in winter and slowly absorbing atmospheric heat in summer) It is a relatively inexpensive building material, providing attractive life-cycle costings, particularly when the building life is relatively short. The amount of energy used to produce ccrete masry is relatively low when compared to most other building materials. Generally, materials that are good thermal insulators are incapable of supporting heavy loads. Cversely, most good load-supporting materials are poor insulators. Ccrete masry is a notable excepti to these general rules. Its good insulating qualities are derived primarily from the minute voids in the ccrete of the units. In general, it will be found that masry units of lower density ccrete will have higher thermal resistance because of their greater voids ctent. Thermal resistance is generally improved by substituting lightweight aggregates for dense aggregates in the masry ccrete. It may be further improved by filling the cores of walls of hollow blocks with granular insulating materials such as perlite or vermiculite. Where cores are filled in this way, measures must be taken to prevent entry of moisture to the wall cores and the core-filling material. Such precautis include the use of cavity wall cstructi, moisture- resistant external coatings and the preventing of water entry by good flashing and weathering practice * * Source: CMAA MA ( / 6 /
