Anti-crack waterproof mass concrete and preparation method thereof
The invention discloses anti-crack waterproof mass concrete and a preparation method thereof. The anti-crack waterproof mass concrete is prepared from the following raw materials in parts by weight: 1000 to 1300 parts of dolomite macadam coarse aggregate, 900 to 1100 parts of siliceous rock artificial sand fine aggregate, 150 to 250 parts of cement, 10 to 20 parts of admixture and 100 to 150 parts of water, the additive comprises zeolite, silane, cellulose ether and a complexing agent. The mass concrete provided by the invention not only can fundamentally solve the problem of mass concrete cracking caused by too high temperature due to hydration of a cementing material in the concrete, but also has the advantages of high strength, relatively strong durability, good impermeability and waterproofness and relatively low cost; the prepared mass concrete is suitable for high-rise building foundations, underground engineering, water conservancy dams and other projects, and can achieve long-term anti-cracking and waterproof effects.
本发明公开了一种抗裂防水型大体积混凝土及其制备方法，包括如下重量分数的原料：白云岩碎石粗骨料1000‑1300份、硅质岩人工砂细骨料900‑1100、水泥150‑250份、外加剂10‑20份和水100‑150份；所述外加剂包括沸石、硅烷、纤维素醚和络合剂。本发明提供的大体积混凝土不仅能从根本上解决混凝土内部由于胶凝材料水化引起温度过高而导致大体积混凝土开裂的问题，还具备高强度、耐久性较强、抗渗防水性好、成本较低的优点；制备的大体积混凝土适用于高层楼房基础、地下工程、水利大坝等工程，能够达到长期抗裂防水的效果。
