A study of intergrinding and separate grinding of blast

01/03/2000 Grinding-related parameters of blast furnace slag cements (BFC), such as Bond grindability, specific rate of breakage and breakage distributions were determined employing separate and intergrinding modes. Strength tests were performed on mortar specimens made by BFC prepared by these modes of grinding to the same fineness.
