Foam concrete is modern building material which combines satisfactory mechanical and heat insulating properties. The developed technology of foam concrete allows obtaining material, which is characterised by wide range of density, without additional thermal treatment. The aim of this research is to elaborate foam concrete compositions with the best rate between mechanical strength and volume weight by controlling technological parameters of producing process as well as adding non-metallic fibers and using pozzolanic admixtures, such as silica fume. In the framework of research basic properties of foam concrete, such as water absorption, compressive strength, density, have been investigated for different mix compositions. The obtained properties of foam concrete have been compared with properties of traditionally used autoclaved aerated gas silicate concrete. Experimental results showed that use of intensive mixers makes it possible to achieve stable mix and high performance properties of hardened material. Density of the material ranged from 400 to 1100 kg/m3 and compressive strength 1 – 10 MPa. Use of pozzolanic micro fillers allows to improve mix stability, compressive strength and decrease value of water absorption of foam concrete.
