摘要：研究了粉煤灰、矿粉和硅灰对透水混凝土力学性能、渗透性能和抗冻性能的影响。结果表明：粉煤灰具有的“形态效应”和“微集料效应”，可以有效改善透水混凝土的工作性能，提高透水混凝土的致密度，从而改善透水混凝土的力学性能、渗透性能和抗冻性能；矿粉可以显著提高透水混凝土的力学性能、渗透性能和抗冻性能，当矿粉掺量小于15%时，提高矿粉掺量可以有效提高透水混凝土的综合性能；硅灰能够大幅度提高透水混凝土的力学性能和抗冻性能，对渗透性能也有一定程度的改善，但提高硅灰掺量对提高透水混凝土力学性能和抗冻性能作用有限，且掺量过高时会对透水混凝土的渗透性能有一定影响。 Abstract: The mechanical property, permeability and frost resistance of pervious concrete with fly ash, slag, and silica fume were investigated. The results show the morpha effect and micro aggregate effect of the fly ash can improve working performance and density of pervious concrete, then contribute to the mechanical property, permeability and frost resistance. Slag can significantly improve the mechanical property, permeability and frost resistance of pervious concrete, when content of slag is less than 15%, increasing content of slag can also improve the properties of pervious concrete. The mechanical property and frost resistance of pervious concrete is drastically improved, the permeability is partly aslo improved, but the admixture has no significant effect on the mechanical property and frost resistance, and the permeability is decreased when the content of silica fume is too high.
