Abstract

The invention relates to a high water retention concrete curing agent. The high water retention concrete curing agent is prepared by the following components in weight percentage: 77 to 92 percent of high molecular polymer emulsion, 1 to 7 percent of film forming auxiliary agent, 5 to 20 percent of powder filler and 0.2 to 0.7 percent of dispersing agent; the high water retention concrete curing agent penetrates concrete by the high penetration action of nano materials to block concrete pores, so that the concrete has the high water retention capability, and the aim of curing the concrete is achieved; when the invention is sprayed on the concrete surface, a dense closing film is formed on the surface and can prevent moisture in the concrete from evaporation.

Description

【Technical field】 [0001] The invention relates to a high water-retaining concrete curing agent, which can be used for airport runways, highways, road bridge tunnels, dams, slope protection and complex-shaped construction projects, and is especially suitable for concrete road maintenance in high temperature seasons, belonging to the technical field of concrete admixtures. 【Background technique】 [0002] Cement needs a lot of water in the hydration process. If there is a lack of water, the hydration process will be delayed or even stopped. 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 existence of a large number of capillary channels in the concrete, the water is easy to lose. At the same time, the evaporation of water and the water absorption of the base layer will also quickly lose the water in the concrete. Therefore, to ensure the process of cement hydration,...
