The Investigation for the Possibility to Utility on the Natural Zeolite and Mud Stone as Admisxture

혼화재로서 천연제올라이트 및 이암의 활용성 검토에 관한 연구

In domestic, there are not adequate admixtures for concrete now, so the study on that is required deeply, Accordingly the purpose of this study is to analyze the application possibilities of Natural Zeolite and Mud Stone as admixtures for concrete through comparing the compressive strength prorerties of mortar mixed with imported Silica Fume those mixed with domestic Zeolite and Mud Stone. As the results from this study, the optimum displacement rate of Silica Fume, Zeolite and Mud Stone is 15%, 5~10%, 15% respectively. In Zeolite and Mud Stone, the compressive strength is higher in proportion as the powder is fine. Consequentely, the application possibility the application possibility of Zeolite and Mud Stone is very sufficient as admixtures for concrete.
