Concrete antifreezing agent and preparation method thereof
The invention relates to the technical field of concrete anti-freezing agents, and discloses a concrete anti-freezing agent which comprises a water reducing component, a slump retaining component, an early strength component, an anti-freezing component, an air entraining component, a water retention component and water, the water reducing component, the slump retaining component, the early strength component, the anti-freezing component, the air entraining component and the water retaining component are prepared from the following components in parts by weight: 50 to 200 parts of the water reducing component, 0 to 150 parts of the slump retaining component, 300 to 400 parts of the early strength component, 250 parts of the anti-freezing component, 0.8 to 1 part of the air entraining component and 30 to 50 parts of the water retaining component; an inorganic-organic composite anti-freezing system is adopted as the anti-freezing component, calcium nitrate and sodium nitrate can promote early strength development of concrete while reducing the freezing point of an anti-freezing agent system, methanol and ethylene glycol components can further reduce the freezing point of the system, it is guaranteed that the anti-freezing agent cannot be frozen and frozen at the low temperature, and the anti-freezing effect is good. The anti-freezing performance of the anti-freezing agent and the performance of promoting the early strength development of the concrete are fully considered, so that the anti-freezing agent has a wider application range.
本发明涉及混凝土防冻剂技术领域，公开了一种混凝土防冻剂，包括减水组分、保坍组分、早强组分、防冻组分、引气组分、保水组分和水，所述减水组分、保坍组分、早强组分、防冻组分、引气组分和保水组分的重量份组成如下：50～200份减水组分、0～150份保坍组分、300～400份早强组分、250份防冻组分、0.8～1份引气组分和30～50份保水组分；本发明中的防冻组分采用无机有机复合的防冻体系，硝酸钙、硝酸钠组份在降低防冻剂体系冰点的同时，可以促进混凝土早期强度发展，甲醇、乙二醇类的组分，可以进一步降低体系的冰点，保证防冻剂在较低的温度时不会受冻结冰，充分考虑了防冻剂本身的抗冻性能及促进混凝土早期强度发展的性能，使其具有更广的应用范围。
