Abstract

The invention belongs to the technical field of concrete, and particularly relates to a chloride-free ammonia-free environment-friendly concrete antifreezing agent and a preparation method thereof. The concrete anti-freezing agent provided by the invention comprises the materials of an early strength component, a plasticizing component, a rapid hardening component, an air entraining component, a water reducing component and a coupling component, and has the characteristics of no chlorine, no ammonia and outstanding anti-freezing performance. The invention also provides a preparation method of the anti-freezing agent, which sequentially comprises the following steps: mixing and preparing the anti-freezing agent precursor, and adding the air entraining component while injecting air, thereby ensuring the effective preparation of the concrete anti-freezing agent.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a chlorine-free and ammonia-free environment-friendly concrete antifreeze and a preparation method thereof. Background technique [0002] Concrete antifreeze can effectively reduce the freezing point of concrete and greatly improve the antifreeze performance of concrete under negative temperature conditions. [0003] Existing concrete antifreeze formulations mainly include early-strength agents, air-entraining agents and water-reducing agents. For example, the Chinese invention patent with the patent publication number of CN 113666660A and the publication date of 2021.11.19 discloses a concrete antifreeze, which includes, in parts by mass, 1-3 parts of early strength agent, 1-2 parts of air-entraining agent, 8-12 parts of polycarboxylate water reducing agent, 6-10 parts of potassium carbonate, 15-25 parts of antifreeze microcapsules. [0004] However, the concrete ...
