Effect of Steel Slag as Partial Replacement of Coarse Aggregate in M35 Grade of Concrete

Aggregates are the important constituents in concrete. In India, annual outcome of Steel Slag is about 10 Million Tone . The utilization of waste materials from the industries has been continuously emphasized in the research work. The present work is to use steel Slag as partial replacement for coarse aggregate. The M35 concrete with steel slag partial replacement for coarse aggregate are examined in the present study. According to material properties studied are 7days and 28days compressive strength, flexural strength and split tensile strength were found experimentally. The results were compared with conventional concrete property. The results showed that partially replacing about 0%, 15 % , 30 %, 45%, and 60% of steel slag aggregates by weight for natural aggregates From these results of the study we can say that as the percentage of steel slag as replacement is increased (0% to 45%) the strength of concrete increases. After 45% replacement of Coarse aggregate as steel slag slight decrease in strength is observe, but still it is higher than 0% replacement without any adverse effect on the strength of concrete.
