混凝土的抗渗性能是混凝土耐久性能的一个重要体现，渗透性能的好坏直接决定着建筑物寿命的长短。本文对混凝土耐久性能的一个重要方面抗渗透能力进行研究，试验组采用的是强度等级为C40的再生混凝土，其再生粗骨料的取代率为80%；对比组是强度等级为C40的天然混凝土。在水压恒定在1.2MPa下24h将试件取出，测定试件的渗水高度。通过实验数据发现，再生混凝土的渗水高度比天然混凝土渗水高度大，但两者相差不是太大。

The permeability of concrete performance is an important embodiment of concrete durability performance,The stand or fall of permeability directly determines the length of the building life.In this paper,an important aspect of the durability of concrete performance is penetration resistance were studied.Experiment group use Recycled Concrete of C40 strength grade,which recycled coarse aggregate replace rate is 80%;Control group use Natural Concrete of C40 strength grade.In the constant water pressure under 1.2 remove the sample after 24 h, then determinate water penetration height of the sample.Through the experimental date ,finding that water penetrating height of Recycled Concrete is bigger than Natural Concrete ,but the different between them is not big.
