The invention relates to the field of concrete, in particular to high-permeability recycled aggregate concrete and a preparation method thereof. The high-permeability recycled aggregate concrete comprises the following components in parts by mass: 100 to 120 parts of cement; 20 to 40 parts of mineral powder; 500 to 650 parts of stone; 50 to 80 parts of water; 2 to 3 parts of a water reducing agent; 100 to 120 parts of recycled fine aggregate; 0.1 to 0.3 part of an air entraining component; and 4 to 8 parts of modified reinforced fibers. The surface of the modified reinforced fiber is coated with silane modified polyether. The high-water-permeability recycled aggregate concrete prepared in the invention has excellent water permeability, and can maintain high frost resistance at the same time.
本发明涉及混凝土领域，尤其是涉及一种高透水再生骨料混凝土及其制备方法。高透水再生骨料混凝土包括如下质量份的组分：水泥：100～120份；矿粉：20～40份；石子：500～650份；水：50～80份；减水剂：2～3份；再生细骨料：100～120份；引气组分：0.1～0.3份；改性增强纤维：4～8份；所述改性增强纤维为表面包覆有硅烷改性聚醚的增强纤维。本申请制备得到的高透水再生骨料混凝土具有优异的透水性能，同时能够保持较好的抗冻性能。
