中文摘要：较大的干燥收缩是引起混凝土开裂的主要原因之一,防治混凝土开裂是保证混凝土质量的重要举措,当前常用的主要技术措施为在优化配合比时掺入有益的矿物掺合料。本文对四种主要的水泥基材料干燥收缩理论及其适用范围进行总结,在此基础上,综述了矿物掺合料的种类、掺量、细度和掺入形式对水泥基材料干燥收缩的影响及其作用机理,指出了当前研究中存在的不足,并对未来研究方向进行了展望。

外文摘要：High drying shrinkage is one of the important causes of concrete cracking.Preventing concrete cracking is an important measure to ensure its quality.The main technical measure currently used is to add beneficial mineral admixtures when optimizing mix proportions.Four prominent mechanisms of drying shrinkage and their application ranges were summarized.Based on this,the effects of different types,amounts,fineness and mixing ways of mineral admixtures on the drying shrinkage of cement-based materials and their corresponding mechanisms were reviewed.The deficiencies of the current research were pointed out,and the future research direction was also expected.
