Abstract：
Ｂlast furnace slag powder was extensively used into concrete. But the bleeding characteristic of blast furnace slag powder frequently results in serious bleeding and dusting of concrete. The various cement replacements by blast furnace slag powder affect on the bleeding characteristic and fresh properties of concrete. It is expected to find out the optimum cement replacement by blast furnace slag powder according to the related test results.
