Anti-freezing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-freezing concrete and a preparation method thereof. The anti-freezing concrete comprises the following components in parts by weight: 30-35 parts of cement; 10 to 15 parts of fly ash; 60 to 70 parts of sand; 80 to 100 parts of fine stone; 20 to 25 parts of water; 0.4 to 0.6 part of a water reducing agent; 1-2 parts of an air entraining agent; 5-10 parts of an auxiliary agent; 10 to 20 parts of an anti-freezing additive; the anti-freezing additive is formed by mixing hollow glass beads and waste rubber particles according to the weight ratio of 1: (1.2-2). The anti-freezing concrete has good anti-freezing performance, and the problems of concrete compressive strength loss and poor durability caused by repeated freezing and thawing can be further relieved.
本申请涉及混凝土领域，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，包括如下重量份数的组分：水泥30‑35份；粉煤灰10‑15份；砂子60‑70份；细石80‑100份；水20‑25份；减水剂0.4‑0.6份；引气剂1‑2份；助剂5‑10份；抗冻添加剂10‑20份；所述抗冻添加剂由中空玻璃微珠和废旧橡胶颗粒按重量比1:(1.2‑2)混合组成。本申请的抗冻混凝土具有较好的抗冻性能，能进一步缓解由于反复冻融导致混凝土抗压强度损失，耐久性差的问题。
