It is shown that the early hydration of C_3S in pure water can be divided into four periods, the second of which corresponds to the so-called induction period and during that period C_3S has a constant dissolution rate.The chemical admixtures do not change the nature of C_3S hydration, but rather, shorten the duration of its induction period. The effect of a chemical admixture on C_3S hydration ra...             本文研究了C_3S在纯水和化学外加剂溶液中水化时,液相成分的变化规律。发现C_3S在纯水中水化可分为4个阶段,其中第Ⅱ阶段相当于水化诱导期,此阶段中C_3S的溶解速度R_0为常数。化学外加剂的存在并不改变C_3S的水化本质,但能缩短水化诱导期。化学外加剂对C_3S水化速度的影响主要取决于组成该外加剂的阴、阳离子的本质。本研究还通过实验证明了硅酸盐离子对Ca(OH)_2核晶过程的“毒化”作用,为C_3S延迟核晶水化理论提供了直接证据。 文摘来源          Hydrogenation was carried out in a "dead-end" type of batch reactor for Chinese rapeseed oil high in erucic acid and sulfur.
