摘要
总结了近些年来在水泥基材料裂缝自愈合领域的研究进展,重点论述了两种普通类型的水泥基材料裂缝自愈合的机理、愈合过程、影响因素及评价。普通水泥基材料裂缝愈合机理包括结晶沉淀、结晶渗透,对聚合物水泥基材料,主要包括空气固化愈合、热聚合愈合和温致愈合机理。并提出了进一步的研究方向。
Advances in research on crack self-healing in cementitious materials in the past years are summarized systematically. Crack self-healing mechanisms,healing process,influencing factors and evaluation of two types of cementitious materials are discussed. The healing mechanism involves crystalline-deposition and capillary-crystalline for normal cementitious materials, and air-curing healing, thermal-polymerization healing and temperature-induced healing for polymer-cementitious materials. Future research direction is also suggested.
