Precautions for Concrete Conservation and Prevention

Maintenance of concrete

After the concrete pouring is completed, the method of covering and watering is used to maintain the shoulder effect to realize the curing of the concrete. In addition, arrange relevant personnel to take care of the concrete to ensure that the concrete is in a wet state. In summer, the maintenance should not be less than 7 days by covering wet grass or watering.

Prevention of concrete cracks

In order to effectively prevent cracks in concrete, the following preventive measures should be taken:

①. Reasonable design of distribution ratio

In the process of concrete proportioning, it is necessary to carry out scientific and reasonable proportioning of various materials so that all aspects can meet the requirements of relevant specifications, effectively reduce the phenomenon of hydrothermalization, and then reduce the amount of water and cement.

②. Select the appropriate concrete pouring method

Several common concrete pouring methods have been introduced above. Selecting an appropriate concrete pouring method in the construction process of a construction project has an important impact on improving the utilization rate of concrete and giving full play to the role of concrete. Therefore, the construction personnel on the project site are required to choose the appropriate concrete pouring method according to the construction situation of the project site and combined with rich construction experience.

③ Pay attention to the maintenance of concrete

Use scientific and reasonable maintenance methods to maintain the concrete, thereby effectively reducing the temperature inside and on the surface of the concrete and slowing down the cooling rate of the concrete to finally achieve the purpose of concrete crack resistance.

All in all, the concrete pouring technology in construction projects has the characteristics of comprehensiveness, systematicness and rigor. It is a rigorous and orderly work, and as an important content in the construction process, it is very important to the overall quality of construction projects Impact. Therefore, the construction personnel of construction projects are required to master the concrete pouring technology and enrich the construction experience of the pouring technology, flexibly choose the corresponding pouring technology plan according to the actual construction situation of the project, and finally give full play to the role of the concrete pouring technology, and promote the construction industry in my country. Good and fast development.

Concrete admixtures for concrete maintenance

Concrete curing compound:

Concrete curing agent, also known as concrete protective agent and concrete curing fluid, is a new type of polymer preparation prepared by modern high technology. It is a liquid film-forming compound with a wide range of adaptability. The product is water-based, non-toxic and non-flammable, and is easy to use. Spray this curing agent on the surface of concrete or mortar. When the water evaporates to a certain extent, it can quickly form a non-toxic layer. Color, impermeable film, can prevent the evaporation of water in concrete or mortar, reduce shrinkage and cracking of concrete. One ton of curing agent can save 2000 tons of water.

Concrete sealer/hardner:

This is a non-toxic, non-combustible, colorless and transparent liquid material with strong penetrating power, which can make the concrete surface sealed and dust-proof, hardened and wear-resistant, and present a permanent luster. It is often used on indoor and outdoor corundum wear-resistant floors, terrazzo floors, raw pulp finishing floors, super-flat floors, ordinary cement floors, stone and other base surfaces. It is suitable for factory workshops, warehouses, shopping malls, supermarkets, docks, and airport runways. , bridges, roads and other cement-based places.
