Impermeable waterproof concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to impervious waterproof concrete and a preparation method thereof.The impervious waterproof concrete is prepared from, by weight, 100-120 parts of cement, 30-50 parts of fly ash, 20-30 parts of mineral powder, 100-150 parts of fine stone, 2-20 parts of polyurethane phase change fibers, 2-5 parts of a water reducing agent and 30-60 parts of water. The polyurethane phase change fibers are added into the concrete, the elasticity and phase change temperature regulation performance of the polyurethane phase change fibers are utilized, the bonding strength of the fibers and the concrete and the temperature stability of the concrete are improved, impermeability and water resistance of the concrete are finally achieved, and the concrete has the effects of a small amount and high efficiency. Meanwhile, the concrete is added in a fiber form, so that the concrete strength is not reduced, and a certain reinforcing effect is achieved.
本发明涉及混凝土技术领域，具体为一种抗渗防水混凝土及其制备方法，按重量份包括：水泥100‑120份、粉煤灰30‑50份、矿粉20‑30份、细石100‑150份、聚氨酯相变纤维2‑20份、减水剂2‑5份和水30‑60份。本发明通过在混凝土中添加聚氨酯相变纤维，利用聚氨酯相变纤维的弹性和相变调温性能，提高纤维与混凝土的结合强度以及混凝土的温度稳定性，最终实现混凝土的抗渗防水，且具有少量高效的作用。与此同时，以纤维形式添加，不仅不会降低混凝土强度，还有一定增强作用。
