Abstract

Foam concrete is a type of aerated lightweight concrete foam concrete does not contain coarse aggregate and can be regarded as an aerated mortar. Foam concrete is produced when pre-formed foam is added to slurry, the function of foam is to create an air voids in cement–based slurry. Foam is generated separately by using foam generator; the foaming agent is diluted with water and aerated to create the foam. The cement paste or slurry set around the foam bubbles and when the foam being to degenerate, the paste has sufficient strength to maintain its shape around the air voids. The foam concrete mixture becomes too stiff with lower content, causing bubbles to break, whereas the mixtures becomes too thin to hold the bubbles with high water content, leading to the separation of bubbles from the mixture, water-cement (w/c) ratio usually ranges from 0.4–1.3. Foam concrete can be designed to have any density within the dry density range of 300–1850 kg/m3. In this investigation two foam concrete mixtures are produced with and without reinforcement and attempts have been made for selecting the proportions of foam concrete mix for the target plastic density of 1900 kg/m3. The specimens are prepared and tested for mixtures, then their physical (Density) as well as specific structural (Compressive Strength) properties were investigated, Specific Strength and Percentage Strength gain for foamed concrete is compared with normal weight concrete and the results are reported. The design and experimental investigation on behavior of reinforced foam concrete beam. Based on the result Ductility and Moment curvature curve was found out for beam.
