Concrete soaking curing refers to pouring water into the concrete surface after pouring concrete, so that it can be fully soaked in water and keep the concrete moist. The main purpose of this curing method is to prevent the water on the surface of concrete from evaporating too fast, maintain the early water content of concrete after curing, and promote the hydration reaction and strength development of concrete. During the curing period, it is usually necessary to keep a certain water layer on the concrete surface, and replenish water regularly to keep it moist.
Sprinkling curing refers to sprinkling curing on the surface of concrete after pouring concrete, but it is not required to soak the concrete in water. This maintenance method mainly reduces the surface temperature of concrete by spraying water, reduces the humidity difference between concrete and the external environment, and prevents the concrete surface from cracking. Sprinkling curing is generally carried out for many times, each time maintaining a certain water humidity, but it is not necessary to form a water layer.
The choice of two curing methods usually depends on the specific conditions and requirements. According to different construction conditions, concrete types and strength grades, as well as environmental factors such as temperature and humidity, choosing appropriate curing methods can better ensure the quality and performance development of concrete.
