This paper presents an investigation of the light weight foamed concrete using recron fiber to increases the compressive strength and various physical and mechanical property .  Hardened foam concrete contains a lot of pore whereas this pore makes it lighter than normal weight concrete and reduces the density.Foam concrete can be designed to have any density within the dry density range of 300–1850 kg/ m . The compressive strength test of the foamed concrete cubes was measured at the ages of 7, 14 and 28 days.10 cube specimens are prepared and tested for mixtures, then their physical (Density) as well as specific structural (Compressive Strength) properties were investigated, gain for foamed concrete is compared with normal weight concrete and the results are reported.
