IS 6072:1971 is the Indian Standard (BIS) for autoclaved reinforced cellular concrete wall slabs. This standard specifies the requirements for materials, dimensions, physical properties, and testing of autoclaved reinforced cellular concrete wall slabs. It covers various grades based on density and compressive strength, intended for use as prefabricated wall panels in building construction.
