Anti-freezing concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses anti-freezing concrete and a preparation method thereof. The anti-freezing concrete comprises the following raw materials in parts by weight: 150-180 parts of water; 340 to 400 parts of a cementing material; 550 to 650 parts of fine aggregate; 1200 to 1400 parts of coarse aggregate; 2-4 parts of a water reducing agent; 0.01 to 0.03 part of an air entraining agent; the air entraining agent is prepared by heating, cooling and concentrating raw materials including an initiator, a catalyst, ethylene oxide, phosphoric acid and o-xylene. The method has the advantage of improving the frost resistance of the concrete.
本申请涉及建筑材料技术领域，具体公开了一种抗冻混凝土及其制备方法。一种抗冻混凝土包括如下重量分数的原料：水150‑180份；胶凝材料340‑400份；细骨料550‑650份；粗骨料1200‑1400份；减水剂2‑4份；引气剂0.01‑0.03份；所述引气剂由包括引发剂、催化剂、环氧乙烷、磷酸和邻二甲苯的原料经过加热、冷却、浓缩制得。本申请具有提高混凝土抗冻性能的优点。
