Abstract

polystyrene is consumed, and is disposed as a waste. On purpose to utilize packing tare waste of expanded polystyrene,
composite material is created. The matrix in this composite material is porous concrete and insertion – crushed tare
waste. The properties of composite matrix are analyzed comprehensively in this article. As it is known, porous concrete
is one of types of lightweight concrete. One of ways to get porous concrete is the usage of surfactants in the formative
mixtures. It has been widely used to decrease the density of concrete and to improve its thermal properties. The
surfactant molecules help entrain air bubbles and stabilize them in the fresh cement paste. Researches with
6 different types of surfactants were made. The Ufapore TCO surfactant was chosen for the further research as the most
suitable for production of composite material.
