Lightweight recycled aggregate pervious concrete and preparation method thereof
The invention provides lightweight recycled aggregate pervious concrete and a preparation method thereof. The lightweight recycled aggregate pervious concrete is prepared from the following raw materials in parts by mass: 30-80 parts of rice hull ash, 200-400 parts of cement, 1100-1500 parts of recycled coarse aggregate, 150-250 parts of shale ceramsite, 0-5 parts of super absorbent resin, 100-150parts of water, 5-15 parts of an additive and 5-15 parts of a reinforcing agent. The rice hull ash, the recycled aggregate and the like are utilized to solve the problem of ceramsite concrete layering caused by low ceramsite density, the pervious concrete with the density smaller than 1600kg/m<3> is prepared, the strength discreteness is low, and meanwhile, the porosity and the water-retaining property of the pervious concrete are increased by utilizing volume shrinkage formed in the water release process of the super absorbent resin.
本发明提供了一种轻质再生骨料透水混凝土及其制备方法，所述轻质再生骨料透水混凝土包括以下质量份数比的原料：稻壳灰30‑80份、水泥200‑400份、再生粗骨料1100‑1500份、页岩陶粒150‑250份、高吸水树脂0‑5份、水100‑150份、外加剂5‑15份、增强剂5‑15份。本发明利用稻壳灰、再生骨料等，解决了由于陶粒密度小而导致的陶粒混凝土分层的问题，制备出密度小于1600kg/m3的透水混凝土，具有强度离散性小，同时利用高吸水树脂在释水过程中形成的体积收缩，增加透水混凝土的孔隙率和保水性。
