ТЕХНОЛОГИЧЕСКИЕ ВОЗМОЖНОСТИ ИСПОЛЬЗОВАНИЯОТХОДОВ ТЕПЛОЭНЕРГЕТИКИ В СЕЛЬСКОМ СТРОИТЕЛЬСТВЕ

The technology of production of wall materials from wastes of heat power engineering - fuel slags with a directionally variable porous structure, is proposed, which creates conditions for light concrete with increased thermal protection and sound absorption capacity. This technology is based on the principle of changing the size of large pores from 5-10 mm on the periphery to 20-40 mm in the center. Slag filler was pretreated with dry waste of chrysotile cement and a polymer-silicate composition to reduce open porosity and reduce the consumption of cement binder. Waste of chrysotile cement positively affects the sound-absorbing characteristics of large-pored lightweight concrete on combined aggregates. Area of application of lightweight large-porous concrete on slag aggregate in the form of wall blocks or monolithic housing construction.
