The Effect of Ground Granulated Blast Furnace Slag Replacement on Alkali -Silica Reaction
- 발행 : 2005.11.01
초록
The effect of ground granulated blast furnace slag to prevent detrimental expansion due to alkali-silica reaction was investigated through the ASTM C 1260 method. This method is one of the most commonly used method because results can be obtained within 16 days. Reactive aggregate used is a metamorphic rock. The replacement ratios of portland cement by ground granulated blast furnace slag were 0, 15, 25, 35 and 55 percent, respectively. The results indicate that 35 percent replacement of portland cement by ground granulated blast furnace slag seems to be effective to reduce alkali-silica reaction expansion under this experimental conditions.
