摘　　要：选取了水泥(Cement,C)、水泥-粉煤灰(Cement-Fly ash,C-FA)、水泥-硅灰(Cement-Silica fume,C-SF)和碱激发粉煤灰矿渣胶凝材料(Alkali-activated Fly ash-Slag,AA-FA-SL)四种胶凝材料体系制备了透水混凝土,并研究了不同胶凝材料体系对透水混凝土抗压强度、透水性能及耐酸雨侵蚀性能的影响。结果表明:C体系透水混凝土透水性能较好,但抗压强度和耐酸雨侵蚀性需进一步提高;C-FA体系透水混凝土具有较好的耐酸雨侵蚀性能,但抗压强度偏低;C-SF体系和AA-FA-SL体系透水混凝土均有合适的抗压强度和耐酸雨侵蚀性能,虽然透水性能略低于C体系透水混凝土但仍能满足工程排水需求;综合考虑使用性能、经济成本以及社会环境效益,制备高性能透水混凝土可优先选用AA-FA-SL胶凝体系。Pervious concrete was prepared respectively with cement(C)system,cement-fly ash(C-FA)system,cement-silica fume(C-SF)system,alkali-activated fly ash-slag(AA-FA-SL)system.The effects of cementitious material system on the compressive strength,permeability and acid rain erosion resistance of pervious concrete were investigated.The results show that cement system pervious concrete has better permeability,but the compressive strength and acid rain resistance to be further improved;C-FA system pervious concrete has very well acid rain resistance,but the compressive strength is poor;C-SF system and AA-FA-SL system pervious concrete have appropriate compressive strength and acid rain resistance,the permeability is slightly lower than that of C system pervious concrete,but still far satisfies the engineering drainage needs;Based on comprehensive consideration of pavement performances,economic costs and social environmental benefits,it is recommended that AA-FA-SL cementitious material system should be selected preferentially to prepare high performance pervious concrete.
