Some Properties of Fiber Reinforced Foamed Concrete

Foam concrete is either a cement paste or mortar classified as lightweight concrete in which air-voids are entrapped in mortar by suitable foaming agent. It possesses high flow-ability low weight minimal consumption of aggregate controlled low strength and excellent thermal insulation properties. By proper control in dosage of foam a wide range of densities (1600– 400 kg/m3). Foamed concrete is a material with a lot of practical aspects a low weight and good thermal conductibility. Due to these good properties the foamed concrete has been used so far mainly as a filling material. The applications in which the foamed concrete would be used as a load bearing material are until now scarce. The reason for that are the fairly low strength parameters.
