地下工程自密实自防水混凝土应用研究
Application Research of Self-compact and Self-waterproofing Concrete in Underground Engineering
摘要
Abstract
Against the problems of crack and water penetration during underground construction using pump concrete,with the admixture of fly ash,expansion agent and retarded high range water-reducing agent,the proportion design is optimized and self-compact concrete is prepared in order to control the crack and meet the requirement of self-waterproofing.Through the laboratory test and engineering practice,it is proven that compound mixed agent effectively improved the fluidity and compactness of concrete,and thus improved the impermeability of concrete,which satisfied the design requirement of self-waterproofing of underground structure.关键词
