Comparison of Mechanical Properties of Foam Concrete Using SLES as Foaming Agent And Different M Sand Proportion
Foam concrete or cellular light weight concrete or reduced density concrete is formed by mixing Portland cement, fine aggregates, water and stable foam. It is called as the cellular concrete because of the pores introduced in concrete due to foam. Foam concrete is being used in non-structural applications extensively like void filling, filling of sunken slab, precast blocks, sub base in highways, prefabricated insulation boards etc., Lot of works are carried out in foam concrete using different kinds of foaming agents and with different mix proportions of cement and fine aggregates. An attempt is made to study the mechanical properties of foam concrete using Sodium Lauryl Ether Sulphate (SLES) liquid as foaming agent and M sand with different mix proportions (cement : fine aggregate). The density of foam concrete was kept constant at 1600kg/m3, the mix proportion was considered as 1:1, 1:1.5 and 1:2 and subjected to compression, split tension, flexure and water absorption tests. These results were compared to the test results of the normal mix without foam. It was noticed that when the percentage of fine aggregate in the foam concrete was increased, the strength reduced drastically and percentage of water absorption increased drastically.
