Effect of Early Compressive Strength Development with Blast Furnace Slag Using Various stimulants Mortar.

각종자극제가 고로슬래그 미분말 혼입 모르타르의 초기재령 압축강도 발현에 미치는 영향

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.
