Testing assures the quality of AAC block… Origins. Although the ASTM C426 procedure permits top and bottom gauges, they are not used very often for concrete blocks. Add the safe work method statement, job safety analysis or safe operating procedure and any additional swms's, jsa's or sop's you require to the shopping cart. This mortar does not require any curing post application. Opening and odd angles should be cut with a handsaw. 3.11 Webs — The solid sections of the hollow concrete blocks which connect the face shells. Hence, few experiments with this kind of reading have been reported. RFIA will be raised to the Engineer to check the work before concreting of tiffener/bonding columns. The width of AAC Block joints to be approximately 3mm with the mortars (as per required by the engineer). DETERMINATION OF WATER ABSORPTION Three full size blocks shall be completely immersed in clean water at room temperature for 24 hours.
