摘要：

This paper aims to characterize the mechanical and physical behavior of non-structural lightweight concrete (NSLWC) produced with volcanic scoria, regarding its application in building's floors. The density, thermal conductivity, capillary absorption, compressive, tensile and punching strength, elasticity modulus, shrinkage, abrasion resistance and behavior at high temperatures of different NSLWC fill solutions were analyzed. For comparison purposes, conventional NSLWC with expanded clay and expanded polystyrene aggregates were also studied. Despite its greater density and slightly lower abrasion resistance and thermal conductivity, NSLWC with scoria showed similar mechanical strength, less shrinkage, higher punching strength and better behavior at high temperatures than conventional NSLWC.
