Optimization design parameters and performance test of C25 pervious concrete

本文对C25透水混凝土的配合比设计及其性能进行研究,根据水胶比、成型方式、石子级配三个参数设计不同的配合比,分析强度及透水性能随参数的变化规律。结果表明水胶比对透水系数起主导作用,成型方式对抗压强度起决定作用,为透水混凝土的优化设计提供一定的借鉴。

This article studies the design and performance of the C25 pervious concrete, considering the water cement ratio, forming method, stone gradation to design different mix proportions, and analyses the influence of the change of parameters on compressive strength and permeability coefficient. The results show that the water cement ratio plays a leading role in the water permeability coefficient, and the forming method plays a decisive role in determining the degree of pressure, which can be used for reference for the optimal design of the pervious concrete.
