混凝土及其构筑物的破损、变形,最终丧失其完整性而不能正常使用,原因是多方面的。本文主要讨论天然骨料及环境条件对混凝土耐久性的影响。同时根据国内外有关研究成果,以及我们对混凝土腐蚀的调查资料,对有关工程地质水文地质条件予以归纳和讨论,提出一些初浅的意见。 Concrete and its structures damaged, deformed, eventually losing its integrity and can not be used normally, for many reasons. This article focuses on the natural aggregate and environmental conditions on the durability of concrete. At the same time, based on the relevant research results both at home and abroad, as well as our survey data on concrete corrosion, some preliminary opinions are put forward by inducing and discussing the hydrogeological conditions of engineering geology.
