摘　　要：随着混凝土技术的快速发展,混凝土塑性收缩开裂加剧的问题同时也摆在研究者面前。对混凝土塑性收缩开裂影响因素(包括环境因素、水灰比、矿物掺合料、化学外加剂等)进行了研究,并提出了预防混凝土塑性收缩开裂的相关措施,如合理使用外加剂(如膨胀剂、纤维和减缩剂)、加强早期养护等,以便为提高混凝土施工质量提供帮助。With the rapid development of concrete technology,researchers are faced with the problems of intensified plastic shrinkage crack of concrete.This paper analyzes the main influence factors(including environmental factors,watercement ratio,mineral admixtures,chemical admixtures etc)of plastic shrinkage cracking of concrete,and it puts forward relevant measures for preventing concrete plastic shrinkage cracking,including the rational use of additives(such as expansion agent,shrinkage reducing agent and fiber),strengthening early maintenance etc.in order to improve the quality of concrete construction
