文摘
Non-structural lightweight concrete (NSLWC) with scoria aggregates was characterized. Its behavior was compared to that of common NSLWC with expanded clay and EPS aggregates. NSLWC with scoria could show, at least, similar compressive and tensile strength. Also had less shrinkage, higher punching strength and better behavior at high temperatures. However, presented greater density and slightly higher thermal conductivity.
