硅酸盐水泥的凝結和硬化,与加水拌和后水化产物的高分散度有关。因此,研究硅酸盐水泥水化时的分散过程,有助于了解水泥的凝結和硬化。我們研究了两种不同細度的硅酸盐水泥在不同分散介质(蒸餾水和石灰飽和溶液)中水化时的分散度。为了比較分散度和液相CaO浓度之間的关系,采用的水灰比为40:1。此外,还进行了标准稠度水灰比試体的强度和結合水試驗。 The coagulation and hardening of Portland cement is related to the high degree of dispersion of hydration products after mixing with water. Therefore, studying the dispersion process of Portland cement hydration helps to understand the coagulation and hardening of cement. We studied the dispersion of two different fineness Portland cements when they were hydrated in different dispersion media (distilled water and saturated lime solution). In order to compare the relationship between the degree of dispersion and the concentration of liquid CaO, a water to cement ratio of 40:1 was used. In addition, strength and bonded water tests were conducted on standard consistency water-cement ratios.
