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.
