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。
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 resuits indicate that the absorptivity and permeability coefficient increases when the w/e ratio is high, and reduces as time developed; the relativity about the strength and the permeability is very good.
