Full-Light-Aggregate Concrete for Structural and Thermal Insulating Wall

Abstract:

An optimal air-entraining agent was selected through a systematically experimental and theoretical study on air-entraining and full-light-aggregate concrete (AEFLC) for structural and thermal insulating wall. Among the three air-entraining agents: rosin acid sodium, Polycarboxylate-type agent, Lauric acid-based agent, Lauric acid-based (Huntsman) air entraining agent was considered the best for the air-entraining quantity and quality. As the result, a AEFLC with the apparent density of 1110kg/m3, compressive strength of 18.8MPa in 28 days, and thermal conductivity of 0.38w/(m.K) was obtained.
