Abstract-The light-weight concrete is a concrete which has a density of 300 to 1850 kg/m3.There are many advantages of having low density. It helps in reduction of dead load, increases the progress of building. The weight of a building on the foundation is an important factor, in case of weak soil. This research focus on reducing the density of concrete by replacing coarse aggregates with bamboo aggregates at different proportion with 10%,20%,30% and 40% respectively. Nowadays,research focus on reducing the self weight of structures, this paper contributes in that area to evaluate the density and workability properties of geopolymer concrete by reducing its density by replacing coarse aggregate with bamboo aggregates. Geopolymer concrete is one of the sustainable concrete in future for developing greener environment by reducing the emission of carbondioxide. This study emphasis to reduce the weight of geopolymer concrete which will help to develop more precast products. Sodium hydroxide of 12M is used in this research. Superplasticizer conplast SP430-Fosroc is used in this study to improve its workability. Low calcium based flyash is used as source material and M-Sand is used as fine aggregate. Density and fresh properties of geopolymer concrete by adding 0.25%,0.5%,0.75% and 1% of superplasticizer by volume of concrete replacing bamboo aggregates are tested.
