Foamed concrete is a highly workable, low density material incorporating up to 50% entrained air. It is generally self-leveling, self-compacting and may be pumped. Foamed concrete is ideal for filling voids such as disused fuel tanks, sewer systems, pipelines and culverts – particularly where access is difficult. Good thermal insulation properties make foamed concrete also suitable for sub-screeds and filling under floor voids.
Foamed concrete is a type of porous concrete similar to aerated concrete. Foamed concrete is created by uniform distribution of air bubbles throughout the mass of concrete.Foamed concrete is used in roof and floor as insulation against heat and sound and is applied on rigid floors in multi-level residential and commercial buildings. It is used in interspaced filling between brickwork leaves in underground walls, insulation in hollow blocks, for the manufacture of precast blocks and panels for curtain and partition walls, slabs for false ceilings etc. It can be used in roofs because of very good insulation and being lightweight.
