메타카올린 치환에 따른 알칼리-실리카 반응 팽창 저감효과
The Effect of Meta-Kaolin Replacement on Alkali-Silica Reaction
- 발행 : 2004.05.01
초록
The effectiveness of Meta-Kaolin to prevent detrimental expansion due to alkali-silica reaction was investigated through the ASTM C 1260 method. Reactive aggregate used is a metamorphic rock. The replacement proportions of portland cement by Meta-Kaolin were 0, 5, 10, 15, 25 and 35 percent, respectively. The results indicate that 25 percent replacement of portland cement by Meta-Kaolin seems to be most effective to reduce alkali-silica reaction expansion under this experimental conditions.
