One of the highest quality materials is called polystyrene concrete. This composite material consists of Silicaucratic Assembly (ash-union with CHP, quartz sand), porous aggregate, many varieties of Portland cement, as well as a large number of modifying additives. The main competitors of polystyrene concrete, aerated concrete and pyno concrete, can only envy its simple manufacturing technology and a wide range of densities (from 150 kgsm3). Small density will allow polystyrene concrete to be used as a heat insulator, and high will give it the opportunity to be involved as a structural material. The material is distinguished by its strength, low thermal conductivity and frost resistance.
