Effect of Limestone Waste as Partial Replacement Material for Sand and Silica Fume in Concrete
This paper presents the results of a study to compare the properties of concretes prepared with the use river sand, limestone waste (LSW), and silica fume (S.F). Two different types of concrete mixture were prepared, and tested in fresh and hardened states. Except for control concrete, quarry waste fine aggregate was used in all concretes as a partial replacement of natural sand. The effects of quarry waste fine aggregate on several fresh and hardened properties of the concretes were investigated. It was found that quarry waste fine aggregate enhanced the slump test of the fresh concretes. But the unit weight concretes were not affected. The investigation included testing of compressive strength, indirect tensile strength, flexural strength, modulus of elasticity, and permeability. However, the best performance was observed when quarry waste fine aggregate was used in presence of silica fume. The overall test results revealed that quarry waste fine aggregate can be utilized in concrete mixtures as a good substitute of natural sand
