Performance Studies of Lightweight Concrete Mixtures Made with Rigid Polyurethane Foam Wastes

Abstract:

This paper describes the results of some studies on the properties of lightweight expanded concrete mixtures made with rigid polyurethane foam waste. Experimental study on the mechanical properties of polyurethane foam waste mixed with concrete shrinkage performance and the relationship between packing density and absolute density. The results showed that: Polyurethane foam plastic waste can be used in the preparation of lightweight concrete, the strength with the state standards, and packing density and concrete absolute density with reference line between sex. Drying shrinkage comply with Selih and Bremner lightweight concrete water content to evolution.
