再生骨料透水混凝土孔分布及成型均质性试验

再生骨料透水混凝土内部孔分布表征成型均质性,从强度和透水性方面影响应用效果。通过体积法配制不同设计孔隙率、不同浆体流动度的RAPC试件,采用自行设计的分层测试方式,对RAPC的孔隙分布特点进行测试试验,揭示不同配合比设计RAPC材料的孔分布特征,为深入了解成型的均质性提供手段,为性能研究提供新视角,对工程中准确设计和应用有指导作用。

The internal pore distribution of recycled aggregate permeable concrete characterizes the forming homogeneity and affects the application effect in terms of strength and water permeability.RAPC specimens with different designed porosities and different slurry flowability were prepared by volume method,and the pore distribution characteristics of RAPC were tested by using a self-designed layered test method,revealing the pore distribution characteristics of RAPC materials with different mix ratios.This study provides a means to deepen the understanding of formation homogeneity and offers a new perspective for performance research,thus guiding the accurate design and application of RAPC in engineering.
