Problems solved by technology

[0002] After the cement concrete is poured, it is necessary to have the necessary temperature and humidity during the initial setting process to ensure sufficient moisture for the hydration reaction to proceed completely. The traditional maintenance methods include laying grass bags, plastic films and watering. These methods are time-consuming , It takes a lot of work, it can’t effectively block the evaporation of water, and the curing effect is not good. The concrete curing agent currently used has brush marks, discoloration or peeling after brushing. After spraying and curing, it affects the appearance quality of concrete, and it is not Concentrated curing agent, the transportation cost is relatively high

Abstract

The concrete curing agent consists of 30-50 wt% concentration styrene-acrylic emulsion in 30-70 weight and 2-10 wt% concentration acrylamide in 30-70 weight, and is prepared through low speed stirring for mixing. The concrete curing agent is sprayed to the surface of concrete to form film avoiding water evaporation and ensuring the fluent hydration reaction in the curing period. The film does not alter the original color of concrete and facilitates the cleaning of concrete surface. During use, the concrete curing agent may be diluted with water.

Description

technical field [0001] The invention relates to a water-based building material, in particular to a concrete curing agent. Background technique [0002] After the cement concrete is poured, it is necessary to have the necessary temperature and humidity during the initial setting process to ensure sufficient moisture for the hydration reaction to proceed completely. The traditional maintenance methods include laying grass bags, plastic films and watering. These methods are time-consuming , It takes a lot of work, it can’t effectively block the evaporation of water, and the curing effect is not good. The concrete curing agent currently used has brush marks, discoloration or peeling after brushing. After spraying and curing, it affects the appearance quality of concrete, and it is not Concentrated curing agent, the transportation cost is relatively high. Contents of the invention [0003] The object of the present invention is to provide a concrete curing agent with good cur...
