    Sep 17, 2009  Abstract. Nowadays line powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by line 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 CO 2 emission than Portland cement.
