An attempt is made in this research work to find out if the foam concrete can be used for industrial roof. Sodium Lauryl Ether Sulphate (SLES) liquid as foaming agent and fine M sand passing through 1.18 mm sieve is used in the present study. Basic mechanical tests were conducted on different densities and cement to sand mix ratios of foam concrete. The obtained results were compared with the test results of the normal mix without foam. From the test results, it was found that the foam concrete of density 1500 kg/m3 and higher with a cement to sand mix ratio of 1:1 can be considered to be used in places where normal cement mortar of cement to sand mix of 1:2 and higher are being used for structural purposes. Two types of foam concrete slabs with different reinforcements and 50 mm thick was subjected to flexural test and checked if it can be used for industrial roof from flexural strength point of view. Both types of foam concrete slab specimens cast satisfied the minimum strength required for the industrial roof subjected to bending both from strength and serviceability point of view. Foam concrete slab of density 1500 kg/m3 with a cement to sand mix ratio of 1:1 of thickness 50 mm with one layer of mild steel welded mesh and 2 layers of hexagonal or rectangular galvanized iron woven mesh can be used as precast industrial roofing element for a span of about 1.7 m.
