    摘要:

    在2种类型石膏（无水石膏和半水石膏）情况下，研究了三乙醇胺（TEA）对掺偏高岭土水泥（MKC）水化进程及其硫酸盐平衡的影响，并与自配硅酸盐水泥（APC）进行对比.结果表明：无TEA加入时，MKC中偏高岭土（MK）的存在可延长水泥的水化诱导期并加快硫酸盐的消耗，2种类型石膏表现基本一致；TEA的加入能够显著促进水泥中铝相矿物的水化，增加硫酸盐平衡所需石膏掺量，同时石膏类型对水泥水化进程与硫酸盐平衡影响显著；对于APC与MKC，在TEA作用下能有效维持其硫酸盐平衡的石膏类型分别为无水石膏与半水石膏，这与水泥中硫酸根离子溶出-吸附-沉淀的动态平衡密切相关.

    Abstract:

    Compared with artificial Portland cement （APC）， the effect of triethanolamine （TEA） on the hydration process and sulfate balance of metakaolin blended cement （MKC） with two types of sulfate carriers （anhydrite and hemihydrate） was investigated. The results show that without the addition of TEA， the incorporation of MK in APC retards the hydration process and stimulates the depletion of sulfate carriers. Different sulfate carriers show similar effects. However， TEA can significantly accelerate the hydration of the aluminate phase and increase the needed amount of sulfate carriers to keep the sulfate balance. Meanwhile， the types of sulfate carriers significantly affect the hydration and sulfate balance. The most suitable sulfate carrier for maintaining the sulfate balance of APC and MKC is anhydrite and hemihydrate， respectively. This phenomenon is related to the dynamic balance of sulfate ions in dissolution-adsorption-precipitation.
