Impermeable concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to impervious concrete and a preparation method thereof.The impervious concrete is prepared from, by weight, 200-300 parts of cement, 900-1000 parts of pebbles, 800-900 parts of sand, 90-110 parts of fly ash, 0.5-1 part of a nano-particle material, 5-10 parts of a phase change expansion anti-cracking agent, 1.5-3 parts of an additive and 150 parts of water; the preparation method of the phase change expansion anti-cracking agent comprises the following steps: uniformly mixing dodecanol and a mixed expansion agent, then adding acidified graphite, uniformly mixing to form a mixture, and carrying out vacuum adsorption on the mixture, so that the dodecanol and the mixed expansion agent are adsorbed in the porous structure of the acidified graphite; the mass ratio of the dodecanol to the mixed expanding agent to the acidified graphite is (35-50): (50-60): (1-5). Under the combined action of the phase-change expansion anti-cracking agent and the nano-particle material, the risk of cracking of the concrete is reduced, and the anti-seepage performance of the prepared concrete is improved.
本申请涉及建筑材料技术领域，尤其是涉及一种防渗混凝土及其制备方法,防渗混凝土，包括由以下重量份的原料制成：水泥200‑300份、石子900‑1000份、砂800‑900份、粉煤灰90‑110份、纳米颗粒材料0.5‑1份、相变膨胀抗裂剂5‑10份、外加剂1.5‑3份和水150份；所述相变膨胀抗裂剂的制备方法为：将十二醇与混合膨胀剂混合均匀，再加入酸化石墨混合均匀形成混合料，将混合料进行真空吸附，使得十二醇及混合膨胀剂吸附于酸化石墨的多孔结构中；所述十二醇、混合膨胀剂和酸化石墨的质量比为（35‑50）：（50‑60）：（1‑5）。本申请在相变膨胀抗裂剂和纳米颗粒材料共同作用下，降低混凝土发生裂缝的风险，提高了所制混凝土的防渗性能。
