The Lightweight Aggregate Concrete is usually produced by using natural and artificial light weight aggregate together with mineral and chemical admixtures. In this study, artificially occurring lightweight expanded clay aggregate was used for the development of structural lightweight concrete to reduce both the high self weight and the negative environmental effects that are typically associated with the production of normal Light Weight Aggregate Concrete. The main purpose of this study is to investigate and compare the behavior of lightweight aggregate concrete and normal weight aggregate concrete and also the study focused on influence of the physical properties of the aggregates on strength development. In this research the investigation done about the use of light weight expanded clay aggregate as coarse aggregate in concrete by replacing normal weight aggregate up to 60% by volume along with the steel fibers to 3 produce a Lightweight Expanded Clay Aggregate Concrete (LECAC) and the unit weight in the range of 1600 kg/m to 1800 3 kg/m . The primary aim of the investigation was to reduce both the economic costs and the negative environmental effects that are typically associated with production of light weight concrete containing artificially produced aggregates by taking advantage of India abundant expanded clay resources. LECA is a lighter aggregate with a higher strength when compared to other artificial light weight aggregates, it allows producing high strength, lightweight concrete that can be used in structural systems of buildings. This study also includes the properties of lightweight expanded clay aggregate concrete such as workability of fresh concrete, compressive strength of cubes at 28 days and 90 days, compressive strength of cylinders, split tensile strength of cylinders, flexural strength of prisms at 28 days.
