Impermeable concrete and preparation method thereof
The invention discloses impermeable concrete which is prepared from the following components in parts by weight: 100 to 200 parts of cement, 15 to 25 parts of coal ash, 2 to 5 parts of additive, 50 to100 parts of water, 300 to 500 parts of sand, 400 to 600 parts of gravels, 15 to 30 parts of mineral powder and 5 to 15 parts of expanding agent. The invention discloses anti-permeability concrete and a preparation method thereof. By means of the additive, disconnected bubbles are generated in the concrete, so that capillary channels are cut off, the pore structure is changed, and thereby the impermeability of the concrete is improved; in addition, the water cement ratio is reduced, cement of proper varieties and strength grades is selected, the construction quality is guaranteed, fine sand and gravels are selected as aggregates, gaps between the aggregates are reduced, and the impermeability is improved.
本发明公开了一种抗渗混凝土，所述抗渗混凝土由以下重分份组成，水泥100‑200份，粉煤灰15‑25份，外加剂2‑5份，水50‑100份，砂300‑500份，碎石400‑600份，矿粉15‑30份，膨胀剂5‑15份。该抗渗混凝土及其制备方法，添加外加剂，使混凝土内部产生不连通的气泡，截断毛细管通道，改变孔隙结构，从而提高混凝土的抗渗性，此外，减小水灰比，选用适当品种及强度等级的水泥，保证施工质量，而选择细小的砂和碎石充当骨料减少骨料之间的空隙，增加抗渗性。
