Strength of Concrete with Partial Replacement of Aggregate with Granite

Concrete demand and consumption are increasing rapidly. On the other hand, the depletion of natural resources and the degradation of the environment is also major concern. The depletion of natural materials can be reduced with the help of recycling and the reuse of the structural members. This paper presents the feasibility of using granite powder (GP) as a partial replacement of the fine aggregate. In a concrete mix of M40 grade, the quality of fine aggregate is replaced by three different percentage (20%, 25%, and 30%) by weight of fine aggregate. The fresh concrete test showed similar results when compared to conventional mix farther cube of size 150 × 150 × 150 mm and cylinder of size 150 × 300 mm is casted for all proportion and cured at normal atmospheric temperature. The test results showed that the normalized compressive strength of cube with 25% replacement of granite powder showed significant increase in strength than the conventional concrete.
