The Effect of Expanded Glass and Crushed Expanded Polystyrene on the Performance Characteristics of Lightweight Concrete

This paper describes the production and performance characteristics of lightweight concrete (LWC) made from porous aggregates, such as expanded glass (EG), waste, crushed polystyrene waste (CEPW), obtained by crushing packaging household appliances ordinary Portland cement (OPC). During study, LWC density, thermal conductivity, compressive strength, bending water absorption, deformations, composite structure, freeze–thaw resistance were evaluated. By changing amount OPC replacing part EG with CEPW, it was possible to reduce conductivity 0.0977 0.0720 W/(mK). The presence CEPW did not degrade strength or long-term absorption LWC. influence aggregates on freezing thawing investigated two methods. In one case, studied method one-sided structural indicators and, in other determined decrease after 25, 100, 200 cycles. modifying structure aggregate durability products increased deformations decreased.
