Concrete antifreezing agent and preparation method thereof
The invention relates to a concrete antifreezing agent and a preparation method thereof. The concrete antifreezing agent comprises, by weight, 30-50 parts of dimethyl sulfoxide; 20-30 parts of a reinforcing agent; 10 to 20 parts of a water reducing agent; 0.5 to 1.0 part of an air entraining agent; 20-30 parts of an early strength agent and water. The concrete antifreezing agent can adjust the workability of concrete and improve the antifreezing performance of the concrete, so that the problems of slow hardening and low strength during negative temperature construction of the concrete are solved.
本发明涉及一种混凝土防冻剂及其制备方法，所述的混凝土防冻剂以重量份数计，包括：二甲基亚砜30‑50份；加强剂20‑30份；减水剂10‑20份；引气剂0.5‑1.0份；早强剂20‑30份和水。本发明所述的混凝土防冻剂可以调节混凝土的和易性，提高混凝土的抗冻性能，从而解决混凝土负温施工时硬化慢、强度低的问题。
