Abstract

In order to analyze alternative materials in concrete, looking for sustainability in civil construction, cylindrical specimens of lightweight concrete were molded with partial substitutions, in mass, of 30% and 70% of the coarse aggregate by expanded clay (AE), also making additions of 20% of silica from rice husk ash (SCCA) in relation to the mass of the binder. From this, the objective is to evaluate the technical viability of lightweight concrete with AE with and without SCCA additions obtaining the specific mass and compressive strength through laboratory tests. As for compression, lightweight concretes that used SCCA obtained better results, however, still lower than the reference.
