High-strength impermeable anti-freezing concrete and preparation method thereof
The invention discloses high-strength impermeable anti-freezing concrete and a preparation method thereof. The high-strength impermeable anti-freezing concrete is prepared from the following raw materials: cement, water, sand, stones, fly ash, an anti-freezing agent, a rust-inhibiting anti-corrosion waterproof agent, waste concrete particles and waste rubber particles. The anti-freezing agent is prepared from the following components in parts by weight: 3.4 to 6.8 parts of modified coal gangue; 1.2 to 2.0 parts of rice hull ash, 1.5 to 3 parts of vinyl acetate-ethylene copolymer latex powder;0.8 to 1.6 parts of silicon powder; 2.4 to 3.8 parts of polypropylene reticular fiber; 0.8 to 1.6 parts of seaweed extract; 0.9 to 1.8 parts of urea; 1.4 to 2.2 parts of calcium nitrite and 10 to 20 parts of water. The high-strength impermeable anti-freezing concrete has the advantages of effective utilization of waste materials, strong freeze-thaw resistance and mechanical properties, reduction of freeze-thaw diseases of concrete in cold regions, and purification of automobile exhaust.
本发明公开了一种高强抗渗抗冻混凝土及其制备方法。高强抗渗抗冻混凝土包括以下原料：水泥、水、砂子、石子、粉煤灰、防冻剂、阻锈防腐型防水剂、废旧混凝土颗粒、废旧橡胶颗粒；防冻剂包括以下重量份的组分：3.4‑6.8份改性煤矸石、1.2‑2.0份稻壳灰、1.5‑3份醋酸乙烯酯‑乙烯共聚物乳胶粉、0.8‑1.6份硅粉、2.4‑3.8份聚丙烯网状纤维、0.8‑1.6份海藻提取物、0.9‑1.8份尿素、1.4‑2.2份亚硝酸钙、10‑20份水。本发明的高强抗渗抗冻混凝土具有有效利用废旧材料，且具有较强的抗冻融性和力学性能，能减少混凝土在寒冷地区冻融病害，且能净化汽车尾气的优点。
