Anti-freezing concrete and preparation method thereof
The invention discloses anti-freezing concrete and a preparation method thereof, and the anti-freezing concrete comprises the following components in parts by weight: 767-829 parts of cement; 875 to 922 parts of coarse aggregate; 250 to 336 parts of fine aggregate; 20-25 parts of an antifreezing agent; 0.2 to 0.26 part of an air entraining agent; 11-13 parts of a water reducing agent; 536 to 666 parts of water; wherein the anti-freezing agent comprises a metal organic framework composite material, and the metal organic framework composite material is obtained by loading nano silicon dioxide on a metal organic framework. The anti-freezing concrete prepared by the invention does not crack at a low temperature, keeps relatively good mechanical strength, and also has good effects of resisting bacteria, resisting corrosion and the like.
本申请公开了一种防冻混凝土及其制备方法，防冻混凝土，按照重量份计，包括如下重量份的组分：767‑829份水泥；875‑922份粗骨料；250‑336份细骨料；20‑25份防冻剂；0.2‑0.26份引气剂；11‑13份减水剂；536‑666份水；其中，防冻剂包括金属有机框架复合材料，所述金属有机框架复合材料采用金属有机框架负载纳米二氧化硅得到。本申请制备的防冻混凝土在低温下不开裂，并保持较好的机械强度，同时还具备抗菌，抗腐蚀等良好的效果。
