Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and in particular to an intelligent temperature control curing system and method for concrete under low temperature conditions. Background Art

[0002] Concrete curing is a vital link in concrete engineering construction. It directly affects the quality and durability of concrete. The purpose of curing is to provide suitable temperature and humidity conditions for concrete so that it can be fully hydrated, develop strength, reduce cracks, and ensure the overall performance of concrete. Normally, newly poured concrete will begin curing after initial setting. The curing time varies according to the strength grade of the concrete and environmental conditions, and is generally not less than 7 days. The temperature of the concrete needs to be controlled during the curing process.

[0003] In a low temperature environment, the cement hydration reaction slows down, which prolongs the setting time of concrete and affects the early strength development. Moreover, if the concrete suffers low temperature frost damage before reaching sufficient strength, it will lose strength. In addition, the freezing and expansion of water will also cause internal cracks, reducing durability and impermeability.

[0004] At present, there are deficiencies in the maintenance technology of concrete in low-temperature environments. Traditional methods are difficult to ensure the early strength development of concrete under low-temperature conditions, which can easily lead to freezing of concrete, leakage and reduced strength. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide an intelligent temperature control curing system and method for concrete under low temperature conditions, which can ensure the curing quality of concrete under low temperature conditions and ensure the early strength development of concrete under low temperature conditions.
