High-water-permeability concrete and preparation method thereof
The invention relates to high-water-permeability concrete and a preparation method thereof. The invention belongs to the technical field of concrete materials. The concrete is prepared from the following components in parts by weight: 230 to 350 parts of a cementing material, 80 to 104 parts of water, 82 to 102 parts of industrial solid waste, 650 to 730 parts of a coarse aggregate, 8 to 10.4 parts of triethanolamine, 10 to 17.6 parts of calcium sulfate whisker, 10 to 13 parts of nano silicon dioxide and 2 to 5 parts of a polycarboxylate superplasticizer. The cementing material is prepared from 180 to 280 parts of cement and 50 to 70 parts of slag, the industrial solid waste comprises 42-50 parts of silica fume and 40-52 parts of fly ash, and the concrete provided by the invention has highwater permeability and strong compressive strength.
本申请涉及一种高透水性混凝土及其制备方法，属于混凝土材料技术领域，混凝土包括以下重量份的组分：胶凝材料230‑350份，水80‑104份，工业固体废弃物82‑102份，粗骨料650‑730份，三乙醇胺8‑10.4份，硫酸钙晶须10‑17.6份，纳米二氧化硅10‑13份，聚羧酸减水剂2‑5份；其中胶凝材料包括水泥180‑280份，矿渣50‑70份；工业固体废弃物包括硅灰42‑50份，粉煤灰40‑52份，本申请的混凝土具有高透水性的同时，具有较强的抗压强度。
