High-pervious concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-pervious concrete and a preparation method thereof. The invention relates to high-permeability concrete, which is prepared from the following raw materials in parts by weight: 200 to 400 parts of cement, 80 to 130 parts of mineral powder, 40 to 60 parts of fly ash, 900 to 1200 parts of bluestone, 300 to 600 parts of cucurbitite, 45 to 72 parts of modified microcrystalline cellulose, 25 to 40 parts of modified polypropylene fiber, 80 to 110 parts of water and 20 to 23 parts of additives. The preparation method comprises the following steps: S1, uniformly mixing the cement, the mineral powder, the fly ash, the bluestone and the melon-like stone to obtain a mixed material; and S2, adding the modified microcrystalline cellulose, the modified polypropylene fiber, the additive and the water into the mixed material obtained in the step S1, and uniformly stirring and mixing to obtain the high-pervious concrete. The high-pervious concrete prepared by the invention is high in strength and excellent in pervious performance.
本申请涉及混凝土技术领域，具体公开了一种高透水混凝土及其制备方法。一种高透水混凝土，包括如下重量份原料：水泥200‑400份，矿粉80‑130份，粉煤灰40‑60份，青石900‑1200份，瓜米石300‑600份，改性微晶纤维素45‑72份，改性聚丙烯纤维25‑40份，水80‑110份，外加剂20‑23份。其制备方法，包括以下步骤：S1、将水泥、矿粉、粉煤灰、青石、瓜米石混合均匀，得到混合物料；S2、将步骤S1所得混合物料中加入改性微晶纤维素、改性聚丙烯纤维、外加剂和水，搅拌混合均匀，制得所述高透水混凝土。本申请制得的高透水混凝土强度高，透水性能佳。
