耐久性对于混凝土来讲意味着安全、经济、持久。由耐久性失效带来的灾难是巨大的,损失是严重的。在一定意义上讲,耐久性有时要比强度更为重要。渗透性作为耐久性的一个重要方面,直接影响混凝土的破坏。因此,研究混凝土的渗透性显得尤为重要。文章通过研究不同掺量粉煤灰混凝土的渗透性,得出混凝土渗透性测试结果(用渗透系数表示),并作与粉煤灰掺量的回归分析,从而得出粉煤灰掺量与混凝土渗透性的关系,得出相应结论。
Durability means safe, economical and long lasting for concrete. The disaster caused by durability failure is enormous and the loss is serious. In a sense, durability is sometimes more important than strength. Permeability, as an important aspect of durability, directly affects the destruction of concrete. Therefore, it is particularly important to study the permeability of concrete. In this paper, the permeability of concrete with different contents of fly ash is studied, the permeability test results of the concrete (represented by the permeability coefficient) are obtained, and a regression analysis with the amount of fly ash is performed to obtain the amount of fly ash and concrete. The relationship of permeability, draw the corresponding conclusion.
