本文主要研究了海洋环境下对磨细矿渣混凝土的影响。本次试验将磨细矿渣混凝土分别放在标准养护条件和海水养护条件下养护，通过改变外加剂用量、水胶比以及用水量，研究影响磨细矿渣混凝土强度的因素。实验分别对两种养护条件下12组磨细矿渣混凝土进行了冻融试验，并在3d、28d、90 d、180 d、360d时进行抗压强度试验，对于混凝土的吸水率、剥落率、相对抗压强度和动弹性模量等参数进行分析。本文以磨细矿渣为混凝土的独立组分。试验结果表明：磨细矿渣微粉能够改善水泥浆体的和易性，增强混凝土的抗渗性能，掺入磨细矿渣的混凝土海水养护条件下强度要高于标养养护强度，海养磨细矿渣混凝土早期强度增加较快，但到后期强度开始下降，但是磨细矿渣的2次水化作用延缓了强度的下降趋势。
