摘要
碱激发水泥力学性能优异,化学耐久性强,是新型胶凝材料。本文综合评述了国内外关于纤维增强碱激发水泥基材料的研究进展,总结了各种纤维对碱激发水泥基材料性能的影响,重点介绍了钢纤维、聚丙烯纤维和玄武岩纤维对碱激发水泥基材料的力学性能、收缩开裂及耐久性的影响,并提出了当前纤维增强碱激发水泥基材料研究中存在的问题和今后的研究方向。
Alkali-activated cement(AAC)is a kind of cementitious material with good mechanical properties and excellent chemical durability.Both domestic and foreign studies on fiber reinforced alkali activated cement-based composites were reviewed in this paper.The influence of fiber categories on the properties of the alkali activated cement based composites was summarized,and the emphasis was placed on the effects of steel fiber,polypropylene fiber and basalt fiber on the mechanical properties,shrinkage,cracking and durability of the alkali activated cement based composites.Some suggestions for future investigation were presented.
