Abstract
The past researches has brought down the various construction challenges such as robust design, practical difficulties, availability of materials and huge cost etc. looks for the possible solution. In the meanwhile, light weight concrete has several potential advantages like reduction of dead load, thermal and acoustic insulation. Consequently the above said challenges will be more suitably addressed in to the light weight concrete which is produced from the various light weight aggregates. Hence, an attempt is made to investigate the performance of light weight concrete using LECA material as a partial replacement for conventional aggregates in the replacement levels of 0%, 5%, 10%, 15%, 20% and 30%. For the casted specimens, mechanical (compressive strength, flexural strength and split tensile strength) and water absorption tests were conducted. In the study, 10% of the LECA material replacement is found to be the optimal percentage in all aspects.
