The invention relates to the technical field of building materials, and provides pervious concrete for a sponge city pavement and a preparation method. The pervious concrete is prepared by mixing heatshrinkable particles, cement, coarse aggregate, fly ash, a water reducing agent, a tackifier and water, wherein the heat shrinkable particles are prepared by coating a heat-shrinkable polymer with acoupling agent. When the pervious concrete is used as the sponge city pavement, the pervious concrete has high strength in winter with low requirements on pervious capacity, and has high strength andhigh water permeability in summer with high requirements on pervious capacity.
本发明涉及建筑材料的技术领域，提供了一种海绵城市路面用透水混凝土及制备方法。所述透水混凝土是由热收缩粒子、水泥、粗骨料、粉煤灰、减水剂、增粘剂、水拌和而制得。所述热收缩粒子是由偶联剂包覆热收缩聚合物而制得。所得透水混凝土用作海绵城市路面时，在对透水能力要求低的冬季具有高强度，在对透水能力要求高的夏季同时具有高强度和高透水性。
