Recycled aggregate pervious concrete with porosity capable of being increased and preparation method thereof
The invention relates to the technical field of concrete, in particular to recycled aggregate pervious concrete with the porosity capable of being increased and a preparation method thereof. The recycled aggregate pervious concrete with the porosity capable of being increased is prepared from the following components in parts by weight: 1090-1178 parts of recycled aggregate, 400-500 parts of 425 Portland cement, 130-155 parts of water, 2-6 parts of a water reducing agent and 42-100 parts of water-absorbing saturated resin balls. The recycled aggregate pervious concrete with the porosity capable of being increased solves the problems that in the pervious concrete forming process, the porosity is low, and communicating pores are prone to blockage. According to the record of the embodiment, the porosity of the pervious concrete can be increased by 3%-8.1% in the later maintenance process. The invention further provides a preparation method of the pervious concrete, the preparation methodis simple and convenient, easy to operate and low in cost, industrial production can be achieved, and sustainable utilization of natural resources is facilitated by using the recycled aggregate.
本发明涉及混凝土技术领域，尤其涉及一种孔隙率可增大的再生骨料透水混凝土及其制备方法。本发明提供的孔隙率可增大的再生骨料透水混凝土，按照重量份数计，包括以下组分：再生骨料1090～1178份，425硅酸盐水泥400～500份，水130～155份，减水剂2～6份和吸水饱和树脂球42～100份。所述孔隙率可增大的再生骨料透水混凝土解决了透水混凝土成型过程中孔隙率低且连通孔隙易堵塞的问题。根据实施例的记载，本发明所述的透水混凝土孔隙率可在后期养护过程中增大3％～8.1％。本发明还提供了所述透水混凝土的制备方法，所述制备方法简便，操作简易，成本低，可工业化生产，使用再生骨料有利于自然资源的可持续利用。
