The High-Strengthing of Concrete with Admixture -On the Crushed Stone Concrete

혼화재에 의한 콘크리트의 고강도화에 관한 실험 연구(I) -쇄석 콘크리트를 대상으로-

The purpose of this study is to raise the strength of concrete with admixture. The natural zeolites and mud stone, abundant in this country, were used as admixture for high-strengthening of concrete. Proper workability was gained by using the superplasticizer. The optimum replacement ratio of zeolite mud stone was 10% on unit -cement amount. At these optimum replacement ratio, the strength development over the plain concrete was 34% for zeolite and 16% for mud stone. Through this study, we concluded the natural zeolite and mud stone were adequate admixture for the high-strengthening of concrete.
