Embodiment 1

[0032] The curing film used for adding water-reducing agent to concrete includes a plastic film 1 and a transparent condensation film 2, and the condensation film 2 covers the surface of the plastic film 1. The material of the film 1 can be plastic, plastic or silica gel. In this embodiment, silica gel is selected. The material of the coagulation film 2 can be plastic film. The film 1 is opaque. After the film 1 is covered on the concrete surface, under the sunlight, because the condensation film 2 is transparent, it is equivalent to the direct exposure of the film 1 to sunlight, the temperature of the film 1 will rise, and the heat of the film 1 will be transferred to the concrete. This causes the temperature of the concrete to rise gradually.

[0033] The mulch 1 is evenly provided with a plurality of storage tanks containing quicklime, the openings of the storage tanks 12 are provided with airbags 13 that can seal the opening of the storage tank 12, and the mulch 1 is provi...

Embodiment 2

[0035] Basic as attached figure 1 Shown: the curing film used for adding water reducing agent to concrete, including transparent mulch 1, which is made of transparent silica gel material, and the mulch film 1 made of silica gel is convenient for processing and storage, and can be folded well.

[0036] The mulch 1 is evenly provided with accommodating chambers and storage tanks 12 containing quicklime. The accommodating cavities and the storage tanks 12 are arranged alternately.

[0037] The opening of the storage tank 12 is provided with an air bag 13 that can seal the opening of the storage tank 12. The air bag 13 is made of plastic material, which has better elasticity.

[0038] Convex lenses 14 are arranged in the accommodating cavities, and the convex lenses 14 here are made of glass. Of course, the material of the convex lens 14 can also be made of transparent plastic, but in consideration of cost, glass is used in this embodiment.

[0039] The mulch film 1 is provided ...

Embodiment 3

[0043] Compared with Example 1, the only difference is that there is an accommodation chamber for accommodating the light concentrator in the mulch film, the middle of the accommodation chamber is thick and the edge is thin, the accommodation chambers are connected to each other, and the accommodation chamber is filled with clean water. Transparent liquids such as chloroform and alcohol can also be used to fill the containing cavity, but in a comprehensive comparison, the cost of clear water is the lowest, so clear water is selected in this embodiment.

Abstract

The invention belongs to the field of concrete curing, and in particular, discloses a curing film for water reducing agent added concrete. The curing film comprises a ground film and a solidification film; multiple storage tanks for accommodating quicklime are uniformly formed in the ground film; airbags capable of sealing openings of the storage tanks are respectively arranged in the openings of the storage tanks; the ground film is provided with a through hole for vertically penetrating through the ground film; and the solidification film covers the whole ground film. Aiming at the technical problems of weak insulation effect at night and easy generation of lower humidity or higher humidity of the surface of the water reducing agent added concrete, the invention provides the curing film for the water reducing agent added concrete.

Description

technical field [0001] The invention relates to the field of concrete maintenance, in particular to a maintenance film for adding water-reducing agents to concrete. Background technique [0002] With the development of science and technology, it has become a common practice to add additives to concrete to change the properties of concrete. In road construction, in order to ensure the quality of the project, polycarboxylate-based high-performance water reducers are usually added to the concrete to ensure the quality of the project. This kind of concrete added with water reducer is called water reducer added concrete. [0003] In conventional concrete curing, for outdoor concrete, the usual curing method is film curing or natural curing. Film curing is to cover the concrete surface with a plastic film, and the water in the concrete evaporates and condenses on the plastic film. To achieve the purpose of ensuring humidity. Natural maintenance is to spread woven bags on the su...
