摘要
透水混凝土是现代城市建设的新型材料之一,具有环境效应小、造价低廉等优点,对改善城市内涝、地下水位低等问题起到了重要作用。为提升其整体性能,借助透水混凝土材料试验,研究了不同骨料粒径和水灰比对其应力、抗压强度、透水系数等指标的影响,并对其抗压强度与透水系数之间的理论关系进行了关系曲线拟合和理论推导,得到了两者变化的一般性规律。
In order to improve the overall performance of permeable concrete, this paper studies the effects of different aggregate particle sizes and water-cement ratios on its stress, compressive strength, water permeability and other indicators with the help of pervious concrete material tests, and the relationship between its compressive strength and water permeability coefficient. The relationship curve fitting and theoretical derivation are carried out on the theoretical relationship between the two, and the general law of the two changes is obtained.
