고강도 시멘트 광물계 급결제를 사용한 숏크리트의 평가

This study is to evaluate the mechanical performance of shotcrete using high-strength cement mineral accelerator. This study has been designed to assess of performance when each 6% of high-strength cement mineral accelerator, and 5%를 of existing cement mineral accelerator are individually mixed to shotcrete. As a result of the study, increase of the shotcrete strength using high-strength cement mineral accelerator at the long-term is approved.
