Abstract

The invention provides a concrete curing compound. The concrete curing compound is prepared from the following raw materials in parts by weight: 8-12 parts of paraffin, 5-20 parts of nano-sized calcium carbonate, 1-7 parts of a coalescing agent, 1-3 parts of sorbitan fatty acid ester, 1-3 parts of triethanolamine, 0.2-1 part of a dispersing agent and 85-100 parts of water. The concrete curing compound has the beneficial effects that the concrete curing compound provided by the invention is high in film-forming speed, high in water-retention rate, long in curing time and convenient to construct, can be normally used under the condition of relatively low external environment temperature; the water-retention rate can reach over 90%; and the concrete curing compound can be directly used without dilution, can be sprayed, brushed and rolled, and is high in compressive strength rate, non-toxic, tasteless, non-inflammable, and free of corrosivity on concrete.

Description

technical field [0001] The invention relates to the technical field of building material additives, in particular to a concrete curing agent and a preparation method thereof. Background technique [0002] Concrete needs a lot of water in the hydration process, and the lack of water will delay or even stop the hydration process. There is a certain amount of water in the concrete mixture, and the mixing water is even greater than the water required for cement hydration. However, due to the There are a large number of capillary channels in the concrete, and the water is easy to lose. At the same time, the evaporation of water and the water absorption of the base layer also make the water in the concrete lose quickly. Therefore, to ensure the smooth progress of the concrete hydration process, it must be moisturized and maintained. [0003] Concrete curing agent, also known as concrete curing liquid, is a kind of coating material. When it is sprayed on the concrete surface, it ca...
