Abstract

The levels of natural sand, a construction material, are depleting and at the same time, demand for new construction is increasing. In this paper, an attempt has been made to replace natural sand with granite fines by adopting M20 grade concrete with a mix design of 1:1.73:3.1 of cement:natural sand and granite powder:gravel at proportions of 0, 10%, 20%, 30% and 40% with a water cement ratio of 0.5. Acid durability test was conducted on concrete cube specimen after 28 days water curing and 62 days soaking in hydrochloric acid. After completion of this procedure, concrete cubes are tested for compressive strength and compared with compressive strength of cubes which are not soaked in HCl after 90 days. The cost analysis is done to ensure usage of granite fines as replacement of natural sand does not vary the cost of project significantly. XRD analysis was done to find out the reasons for the improvement of durability for different proportions of granite fines in concrete.
