Abstract In contradiction to the proposition of Nicoleau and Nonat, it is shown that the rate of hydration of anhydrous tricalcium silicate (C3S) cannot be controlled by the rate of dissolution of the anhydrous phase in typical C3S pastes except at extremely early ages. The strongest evidence for this is the observation that the hydration of C3S in pastes is strongly accelerated by the addition of afwillite seeds, to the extent that it hydrates almost completely by 7 days. It is suggested that the hydration rate at later ages is primarily controlled by the porosity and permeability of the hydration products.

摘要 与 Nicoleau 和 Nonat 的命题相反，研究表明无水硅酸三钙 (C3S) 的水合速率不能通过典型 C3S 糊状物中无水相的溶解速率来控制，除非在极早的年龄。对此最有力的证据是观察到糊状物中 C3S 的水合通过添加粉晶种子而大大加速，以至于它在 7 天时几乎完全水合。表明后期水化速率主要受水化产物的孔隙率和渗透率控制。
