Use of granite waste in high strength concrete made from silica fume

Abstract

The purpose of this research is to study the effects of using granite waste for making high strength concrete. The granite waste was used as natural sand replacement. The granite waste content was 0%, 50% and 100% in mass basis. Also, silica fume was used to produce high strength concrete.  The silica fume was used at the levels of 0%, 3%, 6% and 9% by mass of cement. The concrete properties testing consisted of workability, unit weight, and compressive strength. The results showed that the granite waste can be used to produce high strength concrete. The compressive strength of concrete made with granite waste ranged from 48.4 to 61.2 MPa. It can be concluded that the optimum content of silica fume content was 6%.
