알칼리자극제를 이용한 고로슬래그미분말 혼입 콘크리트의 초기재령 물성평가

Abstract

Based on previous research and existing literature, this study examines the development of admixture, which increases the early concrete strength(1 and 3 days) by mixing blast-furnace slag cement and concrete stimulant. 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 strength 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.
