一、水泥浆中水泥的水化程度在干燥介质中进行热养护,是加速混凝土硬化的一种有前途的方法。研究表明,在非饱和介质中加热混凝土,可使其后期强度提高10～20%。根据有关文献的论述,水泥浆硬化时的物理化学过程的特征是水泥的水化程度和它的动力学,以及新生成物的相组成和它的微观结构。但在以往的文献中,对于干热养护方法对上述这些特征影响如何,则探索较少。基于这样的原因,作者完成了一项试验,目的在于确定水灰比、温度以及热养护时间等因素对在低湿度((?)=5—10%)介质中养护的
First, the degree of hydration of cement in cement paste Thermal curing in drying media is a promising method to accelerate the hardening of concrete. Studies have shown that heating concrete in an unsaturated medium can increase its subsequent strength by 10 to 20%. According to the discussion of the relevant literature, the characteristics of the physicochemical process when the cement is hardened are the degree of hydration of the cement and its kinetics, as well as the phase composition of the new product and its microstructure. However, in the previous literature, there is less exploration on how the dry heat curing method affects these characteristics. For this reason, the authors completed a test to determine the factors such as water-cement ratio, temperature, and heat-curing time for the maintenance of medium with low humidity ((?) = 5-10%).
