Concrete is the cornerstone of buildings. The quality of concrete determines whether the finished building is stable. There are many factors that affect the quality of concrete. Among them, temperature and humidity are the biggest problems. In order to overcome this problem, the construction team usually uses steam to Concrete is cured and processed.
The main purpose of steam is to improve the hardening strength of concrete. Concrete maintenance is an extremely important part of the concrete construction process and is directly related to the construction quality of the entire project. The current economic development is getting faster and faster, construction projects are becoming more and more developed, and the demand for concrete is also increasing.
Therefore, concrete maintenance project is undoubtedly an urgent matter at present. After the concrete is poured, the reason why it can gradually solidify and harden is mainly due to the hydration of the cement. Hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has appropriate hardening conditions, its strength will continue to increase. , concrete must be cured.
Concrete curing in the cold season
The best temperature for concrete molding is 10℃-20℃. If the newly poured concrete is in an environment below 5℃, the concrete will be frozen. The freezing will stop its hydration and the concrete surface will become crispy. Loss of strength, severe cracks may occur, and the degree of deterioration will not be restored if the temperature rises.
Protection in high temperature and dry environments
Moisture is very easy to volatilize under dry and high-temperature conditions. If concrete loses too much water, the strength of the concrete on its surface is easily reduced. At this time, dry shrinkage cracks are prone to occur, which are mainly plastic cracks caused by premature setting of concrete. Especially during concrete construction in the summer, if the maintenance methods are not properly implemented, phenomena such as premature setting, plastic cracks, reduction in concrete strength and durability will occur frequently, which not only affects the construction progress, but also the important thing is to form the structure in this way. The overall quality of the object cannot be guaranteed.
Nobeth curing steam generator generates high-temperature steam in a short period of time to perform steam curing on prefabricated components, creating a suitable temperature and humidity environment to solidify and harden the concrete, improving the efficiency and progress of concrete construction.
