中文摘要:
      透水混凝土是一种绿色生态环保、改善城市生态环境的环保型建筑材料,具有很高的透水率及较高的强度。采用填充理论及体积法设计配合比,验证了改性界面区结构和浆体增强两项性能优化措施的效果,并创新设计综合性能评价方法,从而解决透水混凝土透水性能、密度与力学性能不能兼顾问题,为透水混凝土配合比评估确定提供了方法依据,填补了标准规范空白。
英文摘要:
      Permeable concrete is a kind of ecologically green and environment-protecting building material with good permeability and comparatively high strength,which helps improve the ecological environment of municipalities.In the light of the filling theory and designing the mix ratio by the volume method,the effects of the two performance-optimizing measures——modifying the structure of the interface area and intensifying the slurry body——are testified,with a comprehensive performance-evaluating method designed in a creative way,which helps solve the problems of the water permeavlitiy of concrete,and the contradiction between the density and the mechanical performance of the concrete.The paper provides scientific grounds and methods for evaluating the mix ratio of permeable concrete, filling a blank in the standards and technical specifications.
