Strengthening of RC short column with partial replacement of GGBFS in cement

The manufacturing of cement causes the environmental pollution. In the present study the ground granulated blast furnace slag is used as partially with cement it will reduce the environmental pollution. The GGBFS is the by product from the iron industry, it’s a waste material. The dumping of GGBFS On ground also causes the environmental pollution. The utilization of GGBFS in concrete also reduces the pollution. In the study the cubes are casted to find out the optimum percentage replacement of GGBFS with cement. Based on the optimum percentage the columns are casted. They are tested under axial compression test. After testing the columns are strengthened by using GFRP sheets. The wrapped columns are again tested under axial compression test. From the test results the load carrying capacity of wrapped and unwrapped columns are compared. Finally the numerical analysis is carried out. More over the comparative study is made between the experimental and numerical results.
