Foam concrete work and suggestions and recommendation for the water proofing work to be carried out over it. We are pleased to furnish the details of firm concrete and water proofing treatment as under
INTRODUCTION
Aerated or foamed concrete constitutes an important group in the family of light weight concrete and insulation by incorporating midlands of uniformly distribute non connecting air cells. Foamed concrete has been used extensively in the construction of building where insulation is required
APPLICATION AND USES
As heat insulation materials for roofs where insulation is needed.
To give lightweight and sounded deadening construction.
Can easily be furnished with plaster to provide a hard surface to receive waterproofing treatment.
COMPARATIVE ADVANTAGES
There are several insulation materials in the market, but it is difficult to beat foam, concrete in its versatility and advantages of easy application and economy of cost.
With raw materials like cement and sand, which are available freely, and with a foaming agent, which is formulated out of indigenous materials, the manufacture of foam concrete does not present any problem.
RECOMMENDED SPECIFICATIONS
A coat of hot applied bitumen @ 1.2 kg.per.sq.mtr. Over the slab, where the foam concrete is to be laid as a vapor barrier.
100mm thick average foam concrete (Density - 300 to 325 kg/m) shall be laid over the treated surface.
Cement plaster (1:5) of average thickness 20mm. Over the foam concrete to make the surface harder to receive the water proofing treatment.
Water proofing is needed to preserve the foam concrete to leak proof the building and to maintain insulating value. (Specification enclosed)
