Renewable lightweight pervious concrete and preparation process thereof
The invention discloses renewable lightweight pervious concrete. The renewable lightweight pervious concrete is prepared from the following raw materials in parts by weight: 15-30 parts of cement, 5-10 parts of fly ash, 30-40 parts of modified recycled aggregate, 2-4 parts of a water reducing agent, 10-15 parts of ceramsite, 10-20 parts of mixing water, 3-6 parts of a foaming agent and 2-5 parts of basalt fibers. According to the concrete, the modified recycled aggregate is acidized, so the compressive strength of the concrete is enhanced; meanwhile, the concrete is doped with the basalt fibers, the basalt fibers are resistant to higher temperature compared with carbon fibers, the tensile strength of the basalt fibers can be several times the tensile strength of steel fibers and 10 times the tensile strength of polypropylene fibers, and the basalt fibers are better resistant to corrosion compared with the steel fibers; the tensile strength, crack resistance and durability of the concrete are improved through the basalt fibers, and high-performance concrete can be prepared; and moreover, the price of the basalt fibers is only 1/10 of the price of the carbon fibers and is almost the same as the price of the steel fibers, but the doping amount of the steel fibers is several times the doping amount of the basalt fibers, so the cost of the basalt fibers is lower, and popularization of the concrete is more facilitated.
本发明公开了一种可再生轻质透水混凝土，由以下重量份的原料制备而成：水泥15‑30份、粉煤灰5‑10份，改性再生骨料30‑40份、减水剂2‑4份、陶粒10‑15份、拌合水10‑20份、发泡剂3‑6份、玄武岩纤维2‑5份。本发明中，改性再生骨料经过酸化处理，增强了抗压强度，同时该混凝土掺杂了玄武岩纤维，玄武岩纤维比碳纤维耐高温，抗拉强度可达钢纤维的数倍、聚丙烯纤维的10倍，且比钢纤维耐腐蚀，玄武岩纤维提高了混凝土的抗拉强度、抗裂性、耐久性，可制备出高性能混凝土，同时玄武岩纤维价格仅为碳纤维的1/10，和钢纤维相差无几，但是钢纤维掺量往往是玄武岩纤维的好几倍，所以，玄武岩纤维的成本更低，更加有利于该混凝土的推广。
