Recycled pervious concrete and preparation method thereof
The invention discloses a recycled pervious concrete. The recycled pervious concrete comprises 220-300 parts of cement, 100-150 parts of superfine waste concrete powder, 120 parts of water, 1330-1480parts of coarse aggregate, 80-100 parts of fine aggregate, 8 parts of a pervious concrete synergist and 0.5 part of a polypropylene fiber; and the coarse aggregate is waste concrete particles with theparticle size of 5-20 mm. A preparation method of the recycled pervious concrete comprises the following steps: sorting, crushing and screening the waste concrete; grinding the waste concrete particles with the particle size of 20-40 mm through a ball mill to obtain the superfine waste concrete powder; adding the cement, the prepared superfine waste concrete powder, the fine aggregate and the polypropylene fiber into a stirrer, and fully and uniformly stirring; adding water and the pervious concrete synergist, and stirring to form a uniform slurry; and adding the waste concrete particles withthe particle size of 5-20 mm into the slurry, and fully stirring. The recycled pervious concrete has the advantages of good compressive strength, low cost, environmental friendliness and energy saving. The invention belongs to the technical field of pervious concretes.
本发明公开了一种再生透水混凝土，包括以下组分：水泥220~300份、废弃混凝土超微粉100~150份、水120份、粗集料1330~1480份、细集料80~100份、透水混凝土增效剂8份、聚丙烯纤维0.5份；所述粗集料为粒径5~20mm的废弃混凝土颗粒；制备方法包括以下步骤：将废弃混凝土进行分拣、破碎和筛分；将粒径为20~40mm的废弃混凝土颗粒通过球磨机进行粉磨，得到废弃混凝土超微粉；将水泥、制备好的废弃混凝土超微粉、细集料和聚丙烯纤维加入搅拌机内充分搅拌均匀；加入水和透水混凝土增效剂搅拌成均匀的浆体；将粒径为5~20mm的废弃混凝土颗粒加入浆体中充分搅拌即可；本发明制备出的再生透水混凝土抗压强度好、成本低且环保节能；属于透水混凝土的技术领域。
