Concrete retarder and preparation method thereof
The invention belongs to the technical field of concrete retarder, and particularly relates to a concrete retarder and a preparation method thereof. The invention provides a concrete retarder on the first hand. The concrete retarder comprises a first retarding component, a second retarding component and zinc sulfate, wherein the weight ratio of the first retarding component to the second retarding component to the zinc sulfate is 10: (1-4) : (0.1-1); the particle size ratio of the first retarding component to the second retarding component is (3-10): 1. The invention further provides a preparation method of the concrete retarder. The preparation method comprises the following steps: S1, treating the second retarding component in water at normal temperature for 2-5 minutes; and S2, uniformly mixing the treated first retarding component, second retarding component and zinc sulfate in proportion to obtain the concrete retarder.
本发明属于混凝土外加剂技术领域，具体涉及一种混凝土缓凝剂及其制备方法。本发明第一个方面提供了一种混凝土缓凝剂，所述混凝土缓凝剂包括第一缓凝组分、第二缓凝组分、硫酸锌；其中，所述第一缓凝组分、第二缓凝组分、硫酸锌的重量比为10：(1‑4)：(0.1‑1)；所述第一缓凝组分和所述第二缓凝组分的粒径比为(3‑10)：1。本发明第二个方面提供了上述混凝土缓凝剂的制备方法，包括以下步骤：S1：将第二缓凝组分在常温下放置在水中处理2‑5分钟；S2：将处理后的第一缓凝组分、第二缓凝组分以及硫酸锌按比例混合均匀，得到混凝土缓凝剂。
