초록

This research was performed to evaluate the longitudinal length change ratio of concrete used the expansive admixture. As the results of this study, the compressive strength was shown the highest value at the used 10% expansive admixture both of the dry and wet curing condition. And the length change ration was shown higher 0.0316% and 0.0529 % than that of control in wet and dry curing condition. But this value was not enough to recover the shrinkage occuring by dry shrinkage. According to this study , we have obtained 10% on normal portland cement concrete as the optimum replacement ration of expansive admixture.
