CEMENTITIOUS COMPOSITIONS HAVING COARSE GROUND BLAST FURNACE SLAG AND METHODS OF MAKING AND USING THE SAME |
摘要 |
A cementitious composition capable of forming a high, early-phase strength cement may comprise construction grade cement and ground blast furnace slag, the ground blast furnace slag having a Blaine fineness less than about 250 m2/kg. The cementitious composition may comprise, for each 100% by weight, greater than about 50% by weight construction grade portland cement and less than about 50% by weight ground blast furnace slag, and the cementitious composition may have a Blaine fineness less than about 300 m2/kg. Methods of making and using such a cementitious composition to cement a structure are also described.
