通过测定化学结合水、Ｃａ（ＯＨ）２和ＡＦｔ生成量及观察浆体断面形貌，分别研究了同掺和后掺蔗糖对德国波特兰水泥ＰＺ３５Ｆ水化和凝结的影响，并探讨了蔗糖的调凝机理．蔗糖延缓了ＣＳＨ的形成，加速了（铁）铝酸钙水化产物的形成，浆体的凝结取决于水化产物的生成量，ＡＦｍ及其固溶体可引起浆体闪凝． By measuring the amounts of chemically bound water, Ca(OH)2 and AFt, and observing the cross-sectional morphology of the slurry, the effects of the same blended and post-admixed sucrose on the hydration and condensation of Portland cement PZ35F in Germany were studied, and sucrose was explored. Condensation mechanism. Sucrose delays the formation of CSH and accelerates the formation of (iron)calcium aluminate hydration products. The coagulation of the slurry depends on the amount of hydration product produced. AFm and its solid solution can cause flash condensation.
