摘　　要：采用普通硅酸盐水泥、矿粉、粉煤灰为胶凝材料,制备了C25、C30、C40普通水泥混凝土试件,研究了该混凝土的劈裂抗拉强度、抗压强度、弹性模量、碳化深度以及氯离子扩散系数,并与以海工水泥为胶凝材料制备的海工混凝土相关性能进行了对比。结果表明:当胶凝材料用量相同时,所制备的普通水泥混凝土基本达到海工混凝土的相关性能要求,可用于海洋围垦环境下相关混凝土工程。The C25,C30,C40 ordinary cement concrete specimens were prepared by using ordinary Portland cement,mineral powder and fly ash as cementitious materials.The splitting tensile strength,compressive strength,elastic modulus,carbonization depth and chloride ion diffusion coefficient were studied.The relative properties of marine concrete prepared with marine cement as cementitious material were compared.The results show that when the amount of cementitious materials is the same,the prepared ordinary cement concrete basically achieves the relevant properties requirements of marine concrete,and can be used for relevant concrete projects in the marine reclamation environment.
