Drying shrinkage and Pore Structure of Blast Furnace Slag Concrete Mixed Alkaline Stimulation

알칼리 자극제 혼입 고로슬래그 콘크리트의 건조수축과 공극구조

This purpose of this study is to find the properties of pore structure and length change of blast furnace slag cement added alkali powder stimulant on shrinkage reducing agent presence. In length change, the specimen added alkaline stimulant was smaller than normal blast furnace slag concrete. And the specimen added shrinkage reduction agent was confirmed to show smaller rate of length change than the length. In MIP analysis of 1day-age, 0.1㎛ subsequent pore amount of the specimen added alkaline stimulant was significantly smaller value the normal blast furnace slag concrete specimen.
