High-impermeability concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses high-impermeability concrete and a preparation method thereof. The high-impermeability concrete is prepared from the following raw materials in parts by weight: 200 to 400 parts of cement, 80 to 200 parts of water, 70 to 90 parts of fly ash, 850 to 920 parts of gravel, 0.3 to 5 parts of silane coupling agent, 30 to 60 parts of ethylene-vinyl acetate copolymer and 4 to 12 parts of nano aluminum oxide. The preparation method comprises the following steps: S1, carrying out melt blending on the silane coupling agent, the ethylene-vinyl acetate copolymer and the nano aluminum oxide according to the formula ratio to obtain a blend; s2, uniformly mixing the blend with the cement, the water, the fly ash and the gravels according to the formula ratio to obtain the anti-permeability concrete. According to the high-impermeability concrete disclosed by the invention, the impermeability of the concrete is improved while the strength of the concrete is ensured.
本申请涉及建筑材料领域，具体公开了一种高抗渗混凝土及其制备方法。高抗渗混凝土的制备原料按重量份计，包括水泥200‑400份、水80‑200份、粉煤灰70‑90份、碎石850‑920份、硅烷偶联剂0.3‑5份、乙烯‑醋酸乙烯酯共聚物30‑60份、纳米氧化铝4‑12份；其制备方法为：S1、将配方量的硅烷偶联剂、乙烯‑醋酸乙烯酯共聚物、纳米氧化铝熔融共混制得共混料；S2、将共混料和配方量的水泥、水、粉煤灰、碎石混合均匀制得抗渗混凝土。本申请的高抗渗混凝土在保证混凝土强度的同时提高混凝土的抗渗性能。
