中文摘要：
碱矿渣水泥是具有高强、高耐久性的胶凝材料,但其收缩大,易开裂,是阻碍其广泛应用的主要原因。通过与通用硅酸盐水泥对比,综合评述碱矿渣水泥的收缩与开裂特点及碱矿渣水泥的减缩与增韧的研究现状与存在问题,分析碱矿渣水泥收缩大,易开裂的主要原因,提出了通过掺入膨胀剂、纤维、矿物颗粒和喷洒减缩剂对碱矿渣水泥进行减缩与增韧的建议。
英文摘要：
Alkali-activated slag cement（AASC） is distinguished due to its high strength and high durability.However,its great shrinkage and easy-cracking have restricted the application.Some previous studies on the characteristics of the shrinkage and crack-ing of AASC and the developments on shrinkage-reducing and toughening of the AASC,were reviewed.The issues on the great shrinkage and easy-cracking were discussed.It was proposed that some approaches,i.e.,additions of expansive agent,fibers,mineral particle and spray shring kage-reducing agent,could reduce the shrinkage and increase the toughness to prevent the cracking of AASC.
