This document discusses foam concrete, also known as cellular lightweight concrete. It conducted trials of foam concrete with densities between 300-900 kg/m3 in the lab using cement, sand, and foam. The trials achieved densities of 867, 1134, 845, and 870 kg/m3 respectively. It also discusses uses of foam concrete including roof and floor insulation and precast panels. The document outlines site visits and mixer and foamcrete applications. Advantages noted are adjustable density, low cost, high yield, non-toxicity, reduced dead load, fire resistance, and wall insulation.
