混凝土普通泌水与滞后泌水机理上的区别普通泌水:是由于混凝土组分中较重的固体组分沉降时,组成材料的保水性能差,以致部分拌合水处于分散状态所引起,一般发生在混凝土浇筑后短时间内。严格意义上,泌水是离析现象的一种表现。滞后泌水:是新拌混凝土的初始状态很好,本身具有良好的流动性、粘聚性、保塑性,但浇筑后1~2小时(或较长时间)内,混凝土出现明显的泌水现象,这种现象称之“滞后泌水”。普通泌水与滞后泌水形成机理主要是时间上有明显差异,
Ordinary general bleeding and lagging behind the difference between the bleeding mechanism Ordinary bleeding: is due to the heavier solid components of concrete components settlement, the poor water retention properties of the composition, resulting in part of the mixing water in the dispersion caused by the general Occurred shortly after pouring of concrete. Strictly speaking, bleeding is a manifestation of segregation. Hysteresis bleeding: the initial state of fresh concrete is good, itself has good fluidity, cohesion, plasticity, but after pouring 1 to 2 hours (or longer), the concrete clear bleeding phenomenon , This phenomenon is called “lag bleeding ”. Ordinary bleeding and lagging behind the formation of bleeding mechanism is mainly a significant difference in time,
