Impermeable high-strength concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses impermeable high-strength concrete and a preparation method thereof. The impermeable high-strength concrete comprises the following raw materials in parts by weight: 30-50 parts of cement, 18-30 parts of water, 60-100 parts of river sand, 90-120 parts of stones, 9-20 parts of coal ash powder, 2-5 parts of gypsum, 2-5 parts of calcium oxide, 1-5 parts of rubber particles, 2-6 parts of quartz sand, 3-8 parts of a fiber material and 1-4 parts of an additive. The preparation method comprises the following steps: uniformly stirring the river sand and the stones, adding the cement, the coal ash powder, the gypsum, the calcium oxide, the rubber particles, the quartz sand and the fiber material, performing uniform stirring, adding the water and the additive which are uniformly mixed and stirred, and performing uniform mixing and stirring to obtain the concrete. The components of the impermeable high-strength concrete cooperate with one another and have a synergistic effect, the density of the concrete is improved, the porosity is reduced, pores are cut off, and therefore the anti-permeability and strength of the concrete are improved.
本申请涉及混凝土领域，具体公开了一种抗渗高强的混凝土及其制备方法。一种抗渗高强度混凝土，包括以下重量份数的原料：水泥30‑50份、水18‑30份、河砂60‑100份、石子90‑120份、煤灰粉9‑20份、石膏2‑5份、氧化钙2‑5份、橡胶颗粒1‑5份、石英砂2‑6份、纤维材料3‑8份、外加剂1‑4份；其制备方法为：将河砂、石子进行搅拌均匀后，加入水泥、煤灰粉、石膏、氧化钙、橡胶颗粒、石英砂、纤维材料搅拌均匀，再加入经混合搅拌均匀的水和外加剂，混合搅拌均匀后得到混凝土。本申请的抗渗高强的混凝土各个成份相互配合，协同作用，提高混凝土的密度、降低孔隙率、切断孔隙，从而提升混凝土的抗渗性和强度。
