Studies on Portland cement with large amount of slag

It is necessary to make some technological measures to improve the characteristics of the cement in which a large amount of granulated blast furnace slag (BFS) is added. A few kinds of activators were adopted to develop activity of the cement in this paper. The influence of the additives on the high amount slag cement has been studied. The effect of the compound activators being better than that of an individual one was confirmed by a lot of test data. The optimum ingredient of this blended cement and its powder fineness had been found. (C) 2000 Elsevier Science Ltd. All rights reserved.
