Anti-freezing concrete and preparation method thereof
The invention provides an anti-freezing concrete and a preparation method thereof. The anti-freezing concrete is prepared from, by weight, 1 part of cement, 0.38 to 0.57 part of water, 0.24 to 0.44 part of a mineral admixture, 0.80 to 3.25 parts of iron tailings and waste rock machine-made sand, 2.90 to 4.13 parts of iron tailings and waste rock broken gravels and 0.017 to 0.04 part of a functional anti-freezing admixture, wherein the functional anti-freezing admixture comprises a water reducing agent, an air entraining agent and an anti-freezing agent; and the blending ratio of the water reducing agent to the air entraining agent to the anti-freezing agent is 1: (0.05-0.09): (0.001-0.008). According to the anti-freezing concrete and the preparation method thereof, the concrete with better anti-freezing performance can be obtained.
本发明提供了一种抗冻混凝土及其制备方法。其中的抗冻混凝土以重量份数计，其原料包括：1份水泥、0.38～0.57份水、0.24～0.44份矿物掺合料、0.80～3.25份铁尾矿废石机制砂、2.90～4.13份铁尾矿废石破碎碎石、0.017～0.04份功能性抗冻外加剂；其中，所述功能性抗冻外加剂包括：减水剂、引气剂和防冻剂；所述减水剂、引气剂和防冻剂的掺配比例为1：0.05～0.09：0.001～0.008。通过本发明中的抗冻混凝土及其制备方法，可以得到具有更好的抗冻性能的混凝土。
