폐석탄회를 이용한 고성능 숏크리트의 염소이온 침투 저항성 평가

Abstract

Resently, Underground and tunnel works shotcrete is getting widely applied especially for a large scale project. With incresed significance of durability of concrete structure, intensive studies on numerical analysis for deterioration of the concrete structure due to the chloride attack have been carried out. Thus, this study aims to find an optimum mix proportions for low permeability shotcrete using industrial by-product from power plants. Chloride ion penetration resistance test with fly-ash and silica fume performed to determined the high durability and low permeability mix proportions.
