In the experiment, we add to NaOH, Ca(OH)2 and Calcium Hydroxide as the Slag stimulus also mixed the cement stimulus such as NaSCN, TEA and CaCl2 for improving compressive strenth of concrete which added the Blast Furnace Slag Powder at 1 and 3 days. In the result of strength test, It showed that 2percentage of activator 1 and 5percentage Ca(OH)2, 1percentage of activator 3 and 5percentage of Ca(OH)2 are higher than 100 percentage OPC.
