Abstract

The objective of this study is to improve the quality of concrete, which has been getting worse with high amount of unit water, by using Expansive Additives. 6% of addition ratios of expansive additives with the combination of 45%, 55% of W/B are selected under various amount unit water for this experiment. According to the experimental results, less than 180kg/$\textrm{m}^3$ of unit water has little influence on compressive strength and less length-change has been fond in 45% of W/B.
