摘　　要：硫铝酸盐水泥作为我国第三系列水泥,既是一种低碳绿色水泥,又是一种海工修补加固水泥。铝凝胶(AH_(3))是其最重要的水化产物之一,可有效提升该系列水泥石的宏观力学性能。本文结合化工中AH_(3)的基础研究,阐述了硫铝酸盐水泥石中AH_(3)的形成过程,归纳了AH_(3)的一般性特征,对比了化工中AH_(3)与硫铝酸盐水泥石中AH_(3)的异同点,具体分析了各类因素对AH_(3)微纳结构及含量的影响,总结了目前AH_(3)研究的不足之处,提出了未来研究的方向和思路。Calcium sulfoaluminate(CSA)cement,as the third cement series in China,is not only a kind of low-CO_(2)cement,but also a kind of repairing cement in offshore and coastal structure engineering.Aluminum hydroxide gel(AH_(3))is one of the most important hydration products in CSA cement,which significantly contributes to the macro-properties.Based on the theoretical research of AH_(3)in chemical engineering,a review on AH_(3)in CSA cement is comprehensively represented,including the formation process of AH_(3),the general characteristics of AH_(3),the similarities and differences between AH_(3)in chemical engineering and that in CSA cement,and the influence of various factors on the microstructure and content of AH_(3).Furthermore,the current shortcomings and the future opportunities regarding AH_(3)in CSA cement are discussed.
