Preparation method of high-impermeability concrete
The invention discloses a preparation method of high-impermeability concrete. The preparation method comprises the following steps: 1, weighing 50-80 parts by weight of fly ash, 30-40 parts by weightof blast furnace slag powder, 15-20 parts by weight of silica fume, 10-15 parts by weight of a grinding aid, 20-30 parts by weight of a water reducing agent, 200-300 parts by weight of cement, 100-120parts by weight of sand, 60-80 parts by weight of broken stone and 110-150 parts by weight of water; 2, adding fly ash, blast furnace slag powder, silica fume and a grinding aid into ball milling equipment, and carrying out mixed grinding to obtain composite mineral ultrafine powder for later use; 3, mixing cement, sand and the composite mineral ultrafine powder to obtain a mixture, adding crushed stone, and stirring to obtain a raw material; 4, fully stirring a water reducing agent and water, adding the mixture into the raw materials, and stirring for 15-20 minutes to obtain a concrete mixture; and 5, loading the concrete mixture into a mold, standing, removing the mold after hardening, and curing according to a conventional curing mode to obtain the high-impermeability concrete.
本发明公开了一种高抗渗混凝土的制备方法，包括如下步骤：第一步：按重量份称取粉煤灰50‑80份、高炉矿渣粉30‑40份、硅灰15‑20份、助磨剂10‑15份、减水剂20‑30份、水泥200‑300份、砂100‑120份、碎石60‑80份和水110‑150份；第二步、取粉煤灰、高炉矿渣粉、硅灰和助磨剂，加入球磨设备中，混磨得到复合矿物超细粉体，备用；第三步、将水泥、砂及复合矿物超细粉体混合得到混合物加入碎石搅拌，得到原料；第四步、将减水剂与水充分搅拌、加入到原料中，搅拌15‑20min，得到混凝土拌合物；第五步、将混凝土拌合物装模静置，待硬化后拆模，按常规养护方式进行养护，得到高抗渗混凝土。
