Lightweight concrete in hot coastal areas

Abstract An experimental study was carried out to examine different mixtures made with selected lightweight aggregates for the purpose of producing lightweight concrete. A relatively suitable product is sought in order to provide good quality building materials that can satisfy the conditions of hot coastal environments. Three ways of producing lightweight concrete were used, i.e., lightweight crushed bricks, lightweight expanded clay aggregate (LECA), and no-fines concrete. Physical and mechanical properties of the mixtures were examined to ascertain the suitability and applicability of the three concretes. The results of this pilot study suggest that there are possibilities of producing structural lightweight concrete using crushed bricks with the condition of further refinements in the mixture design.
