Abstract

[Energy-efficient buildings are one of the very important issues recently, which consider both economic and environmental factors. In this paper, main focus was to develop cost effective and durable lightweight concrete having high thermal insulation properties using different grades of light expanded clay aggregate (LECA) as coarse aggregates. As a part of the study, optimization of LECA aggregates, ordinary Portland cement (OPC), and water/cement (w/c) ratio were done. The uniaxial compressive, flexural strength, and drying shrinkage of the developed lightweight aggregate concrete (LWAC) specimens have been determined along with thermal conductivity. The results revealed that compressive and flexural strength of the developed LWAC blocks was in the range of 16.7–23.9 MPa and 2.8–3.4 MPa, respectively. Thermal conductivity of the LWAC specimens were found in-between 0.23 and 0.30 W/m K. From the analysis, it was inferred that the LECA concrete shows good strength at lower density, lower thermal conductivity, and lower drying shrinkage that makes it a suitable material for building constructions.]
