| 摘 要： | 论述了混凝土的渗透性对耐久性能的影响，研究了不同水灰比混凝土各龄期的渗水、吸水性能；并且探讨了混凝土强度与吸水性能、渗水性能的相关关系。试验结果表明：水灰比越大，龄期越短，混凝土的吸水性系数和渗水性系数越大；混凝土强度与吸水性能、渗透性能的相关性较好。

| Abstract: | This paper describes the influence of the concrete's permeability to structural durability;and studies the water absorptivity and permeability of concrete for different water-cement ratio at different curing age;then discusses the relativity about the strength and the absorptivity,as well as the permeability.The results indicate that the absorptivity and permeability coefficient increases when the w/c ratio is high,and reduces as time developed;the relativity about the strength and the permeability is very ... |
