Anti-cracking and anti-seepage concrete
The invention discloses anti-cracking and anti-seepage concrete. The anti-cracking and anti-seepage concrete is prepared from the following raw materials in parts by mass: 112 kilograms to 210 kilograms of Portland cement, 320 kilograms to 550 kilograms of an expanding agent, 0.15 kilogram to 0.85 kilogram of cellulose, 5 kilograms to 8 kilograms of a water reducing agent, 4 kilograms to 10 kilograms of triethanolamine, 20 kilograms to 40 kilograms of redispersible latex powder, 1.2 kilograms to 3.2 kilograms of quick-drying lithium carbonate and 50 kilograms to 80 kilograms of silica fume. According to the anti-cracking and anti-seepage concrete disclosed by the invention, by adding the redispersible latex powder, the quick-drying lithium carbonate and other components, the anti-cracking effect of the concrete can be effectively achieved, the generation and expansion of cracks can be delayed, the cracks can be reduced and refined, and the compactness of a concrete matrix is greatly improved; the impermeability, the freezing resistance and the harmful medium erosion resistance of the concrete are greatly improved.
本发明公开了防裂抗渗混凝土，所述防裂抗渗混凝土按照以下原料的质量份数进行配比：硅酸盐水泥112公斤‑210公斤、膨胀剂320公斤‑550公斤、纤维素0.15公斤‑0.85公斤、减水剂5公斤‑8公斤、三乙醇胺4公斤‑10公斤、可再分散性乳胶粉20公斤‑40公斤、快干碳酸锂1.2公斤‑3.2公斤、硅灰50公斤‑80公斤、粉煤灰16公斤‑20公斤，本发明防裂抗渗混凝土，通过添加的可再分散性乳胶粉、快干碳酸锂等成分，能够有效的达到混凝土的阻裂效应，能延缓裂缝的产生和扩展，减少及细化裂缝，极大地增加了混凝土基体的密实性，大大提高了混凝土的抗渗性、抗冻性及抵抗有害介质侵蚀能力。
