    Sep 17 2009 Nowadays limestone powder and blast furnace slag BFS are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete since the production of these two materials needs less energy and causes less CO2 emission than Portland cement. Moreover the use of limestone
