采用内掺氯化钠的方法,并借助X射线衍射仪和差式扫描量热仪,研究了碳化环境下粉煤灰和矿渣微粉对固化态氯离子稳定性的影响。结果表明:碳化环境下,固化态氯离子将失去稳定性,重新转变成游离态氯离子,而Friedel盐和水化硅酸钙(C-S-H)凝胶的分解是其失稳的主要原因;粉煤灰和矿渣微粉对固化态氯离子在碳化环境下的稳定性存在一定程度的负面影响,会加速其向游离态氯离子转变,尤以粉煤灰影响更甚;碳铝酸盐仅是Friedel盐碳化过程一个过渡性产物,其最终也将因为碳化而分解。
The effect of fly ash and ground granulated blast-furnace slag (GGBS)on the stability of bound chloride ion under carbonation condition was investigated via an inner-induced sodium chloride method.The samples were characterized by X-ray diffraction and differential scanning calorimeter,respectively.The results show that the bound chloride ion will lose its stability and become free under carbonation condition,resulting in the dissolution of the Friedel salt and C-S-H gel.The fly ash and GGBS both have a negative effect on the stability of bound chloride ions under such a condition,and their addition can accelerate the transformation of chloride ions from binding to free,especially for fly ash.It is also certified that calcium monocarboalumi-nate hydrate,which is a sole transitional product in the Friedel salt carbonated process,can be dissolved due to the carbonation reaction.
