Properties of Granite Powder Concrete

Abstract

Experimental Investigation on locally available granite powder as a replacement of sand and partial replacement of cement with admixtures in the production of concrete is presented in the paper. The intention of the research is to find the alternate source and fulfil the scarcity of river sand. To study the effect of Granite Powder (GP) on concrete properties, the percentage of granite powder added by weight was 0, 25, 50, 75 and 100% as a replacement of sand used in concrete and cement was replaced with 7.5 % silica fume, 10% fly ash, 10% slag and the dosage of superplasticiser added 1% by weight of cement. The investigation proved that granite powder of marginal quantity as partial sand replacement together with admixtures in concrete mixture has beneficial effect on concrete properties. Therefore, it can be concluded that the granite powder concrete will boon to the construction sector with strength augmentation.
