Abstract |
In this study, to improve the early-age compressive strength of mortar, the compressive strength tests of mortar mixed smart BFS powder added powder of rapid setting additives milled by processing, using functional grinding aid, the power-typed rapid setting cement clinker developed by sintering industrial waste and by-products with much CaO-SiO2-Al2O3 to cement were performed. From the tests, the followings are found that (1) for BFS early-age strength improvement test (Series I): early-age strength improvement of BFS mixed rapid setting additive milled after adding functional grinding aid, when the clinker is milled, is superior and (2) for OPC early-age strength improvement test (Series II): case of additive mixed rapid setting powder typed activator milled after adding functional grinding aid to Clinker-C showed the higher compressive strength.
