摘 要:介绍了一种利用X-CT技术表征透水混凝土试件内部孔结构并获得连通孔隙的方法,研究了水灰比、骨灰比和骨料粒径对试件透水系数、孔结构的影响,分析了有效孔隙率与总孔隙率之间的关系,并建立了透水混凝土透水系数的经验模型。结果表明:增加水灰比会降低试件的透水系数和连通孔隙率;随着骨灰比和骨料粒径的增加,试件的连通孔隙率和透水系数呈上升趋势。
Abstract: A method was introduced to characterize the internal pore structure of pervious concrete specimens and obtain connected pores using X-CT technology. The effects of water-cement ratio, aggregate-cement ratio, and aggregate particle size on the pervious coefficient and pore structure of specimens were studied. The relationship between effective porosity and total porosity was analyzed, and an empirical model for the pervious coefficient of pervious concrete was established. The results indicate that increasing the water-cement ratio will reduce the pervious coefficient and connectivity porosity of the specimens. As the aggregate-cement ratio and aggregate size increase, the connectivity porosity and pervious coefficient of the specimen show an upward trend.
