目前我国正在混凝土养护工艺上以干热养护代替传统的普通蒸汽养护。干热养护采用热空气,改变混凝土的热养护条件,在生产实践中显示许多优点:制品表面平整、生产周期缩短及热耗降低。水是水泥水化反应的必要组分,在水泥粒子周围需要充足的水量才能完成反应过程及水化产物的成核、结晶过程。干热养护不可避免地使混凝土失去部分水分,在水泥浆体
At present, China is replacing the traditional ordinary steam curing with dry heat conservation on the concrete curing process. The use of hot air for dry heat maintenance changes the thermal curing conditions of concrete. It shows many advantages in production practice: the product surface is smooth, the production cycle is shortened, and the heat consumption is reduced. Water is an essential component of the hydration reaction of cement. A sufficient amount of water around the cement particles is required to complete the reaction process and the nucleation and crystallization processes of the hydration products. Dry heat curing inevitably causes the concrete to lose some moisture, in the cement slurry
