The major challenge in the recent construction sector is to design the building with the cost effective manner. In order to address this issue, self weight of the structural member has to be reduced considerably, and then simultaneously the dimensions will be minimized. This will be only by means of introducing light weight concrete (LWC). Different light weight aggregates are used by the past researches to reduce the density. This study is planned to achieve the properties of LWC in considering the importance to enhance the strength factors. Hence, in this experimental investigation, the influence of the silica and pumice stone is studied on the various partial and full replacement levels. The specimens are casted based on the arrived mix proportion and tested against compression, split tension and flexure. The test result shows 0.6 to 0.7 times the strength achieved of the conventional concrete for this developed LWC mix proportion. A considerable improvement is seen in the strength parameters by the presence of 5 % silica fume.
