Experimental Investigation on Mix Proportion Design for Foam Concrete

1K. Chaitanya Kumar and H. Thiagu


An experimental investigation is done on finding the design mix proportion for foam concrete. Foam concrete is light weight concrete made with cement, fine aggregates and foam. Coarse aggregates are not used. It has excellent properties like low density, fire resistance. Using foam concrete in constructions, it reduces dead loads on structures and foundations and lowers labor cost during constructions. In foam concrete, the foam is produced from foam generator. The equipment which also helps in foam production is air compressor. In this right amount of foam density can be adjusted. The foam generator hassingle phase motorinside the machine and also it contains aninlet valve, an outlet valve, and pressure valve. The various mix designs are prepared using fine aggregate, cement and different percentages of foam. The foam is prepared using protein-based foaming agent. These foaming agents create air bubbles. These air bubbles reduce the surface tension. Various trial mixes are prepared and the compressive strengths are calculated. The right trial mix with more compressive strength is selected.
