当前多数观点认为,混凝土热养护过程的强度损失是属物理原因,即液相与气相热膨胀所造成.而长期以来所采用的混凝土湿热养护方法,在升温阶段热质传输却导致了剩余压力等不利因素的增加,从而加剧了对混凝土结构的破坏作用.因此,这种多从传热学的角度来考虑加速结构形成的湿热养护方法,很难得到品质优良的混凝土.这样一来,就促使人们不断寻求和探索新的养护途径.干湿热养护就是在这种情况下为人们所注目的.
At present, most viewpoints hold that the strength loss of the concrete heat curing process is a physical cause, that is, the thermal expansion of the liquid phase and the gas phase. However, the long-term use of the concrete heat and humidity curing method has caused the remaining pressure and other disadvantages in the heat transfer during the heating stage. The increase of factors has exacerbated the destructive effect on the concrete structure. Therefore, considering the method of heat and heat curing that accelerates the formation of the structure from the perspective of heat transfer, it is difficult to obtain high-quality concrete. As a result, people are encouraged. Continuously seek and explore new ways of conservation. Wet and dry heat conservation is what people pay attention to in this situation.
