研究了添加0.0%、0.1%、0.5%和1.0%三乙醇胺对3CaO·SiO2和β 2CaO·SiO2水化特性的影响。在第1、3、7或28天发现的Ca（OH）2的量的顺序为C3S +0%TEA> C3S +0.1%TEA> C3S +0.5%TEA> C3S +1.0%TEA，无论石灰是否通过X射线、DTA、TGA或化学分析来估计。就3CaO·SiO2的消失而言，水合速率表明在TEA存在下1天后水合进行得更快。TEA的添加增加了诱导期，促进了具有较高CaO/SiO2比的C-S-H的形成，增加了非结晶Ca（OH）2的形成，并提高了水合硅酸盐产物的表面积。
The hydration characteristics of 3CaO.SiO2 or β2CaO.SiO2 are studied by an addition of 0.0, 0.1, 0.5 or 1.0% triethanolamine. The amount of Ca(OH)2 found at 1, 3, 7 or 28 days was in the order C3S + 0% TEA > C3S +0.1% TEA > C3S + 0.5% TEA > C3S+1.0% TEA, irrespective of whether lime was estimated by X-ray, DTA, TGA or chemical analysis. The rate of hydration, in terms of the disappearance of 3CaO.SiO2, showed that hydration proceeded faster in the presence of TEA after 1 day. Additions of TEA increase the induction period, promote the formation of a C-S-H with higher CaO/SiO2 ratio, increase the formation of non-crystalline Ca(OH)2 and enhance the surface area of the hydrated silicate product.
