Abstract

The invention discloses a method for cutting concrete. The method comprises the following steps of spraying water on the surface of the concrete; and sticking a plastic film on the surface of the concrete by using an adhesive. According to the technical scheme provided by the invention, the plastic film is bonded and adsorbed on the surface of the concrete by using the adhesive; a curing mode is simple in operation and is particularly suitable for curing a concrete facade; the curing process has no adverse influence on concrete materials; the quality of the concrete can be greatly improved, and water for curing the concrete is reduced; timing sprinkling by specially-assigned persons is not needed, so that water resources are saved, and labor force is saved; and the method has important significance for improving an urban environment and fills up a technical blank in the field of concrete construction.

Description

technical field [0001] The invention relates to the technical field of concrete maintenance, in particular to a concrete maintenance method. Background technique [0002] Moisturizing and curing after concrete pouring is a key link to ensure quality, and it is a technical problem that needs to be solved. Current common practices include: [0003] Sprinkling method: Special personnel regularly and quantitatively water to keep the concrete surface moist; [0004] Brushing curing agent: brushing liquid curing agent on the concrete surface, the curing agent forms a dense film, which is used to prevent the evaporation of moisture inside the concrete, so as to achieve the purpose of moisturizing; [0005] Covering method: Cover the concrete surface with a layer of moisturizing material (plastic film, grass curtain, etc.). [0006] However, these methods all have some disadvantages, such as the watering method wastes water, needs regular watering, and wastes manpower; the coveri...
