Technical Field
The invention relates to a concrete curing technology in a strong wind arid area.
Background
In the process of road construction, for concrete structures with large surface areas, such as concrete pavements, cement stabilizing layers and the like, maintenance after construction is very critical and necessary. If the curing conditions do not meet the standard requirements, for example, the humidity of the concrete surface is low during curing, or the curing time is short, the strength of the concrete does not meet the design requirements, even cracks are generated on the concrete surface, and the durability and the mechanical property of the concrete are reduced. Particularly, in the northwest of China in windy and arid areas, the problem of performance reduction of concrete caused by inadequate maintenance is more prominent.
In the present stage, in the windy and arid areas in northwest China, in order to ensure the maintenance quality of the concrete structure with large surface area, more measures are also taken on site, and certain effect is achieved. However, the following problems are mainly involved in curing: (1) by adopting the modes of covering canvas and geotextile on the surface, adding a dropper below and the like, the maintenance of concrete can be effectively ensured, but the surface covering is easily blown away under the strong wind condition. Even if the weight is pressed around the cover, the air inlet phenomenon appears under the cover due to the fact that the weight cannot be tightly arranged around the cover, and the maintenance effect is poor. (2) And covering a health preserving film on the surface of the concrete for curing. However, in northwest China, because the water content in the concrete mixing proportion is often controlled to be relatively low, when the concrete is maintained in the mode, the water content in the concrete cannot meet the maintenance requirement, and the maintenance effect is also not ideal. Therefore, a maintenance device which can be applied to concrete with large surface area in a strong wind and dry area is urgently needed in the road construction at the present stage.
