Study on Properties of Lightweight Aggregate Concrete Characterized by Environment Protection

Abstract:

To prepare concrete by applying industrial or agricultural wastes (energy saving materials) and natural lightweight aggregates, is a new pathway to develop lightweight aggregate concrete. The waste cornstalk, rubber particles made with industrial wastes, polyphenyl granules and natural pumice, as lightweight aggregates, are organically mixed with cement according to certain of proportion, so a kind of new multiphase composite lightweight aggregate concrete was prepared. The research results indicate that the raw materials after pretreatment can form good interfacial bonding with cements, improve further the performances of hardened concrete. The good workability, certain strength and low apparent density of concrete could be guaranteed.
