摘　　要：针对现行规范中混凝土收缩试验方法存在歧义的问题,分析了试验测试参数的相互关系及影响因素,提出了测量标距、测量长度等涵义准确的规范化术语以及混凝土干缩率计算公式,细化了混凝土收缩仪的操作使用方法.In view of the ambiguity existed in test methods for concrete shrinkage in current standards, the relationships and factors of measuring parameters are analyzed, the normalized terms and their definitions such as the measuring scale distance and the measuring length coincided with the formula for the shrinkage ratio of concrete are suggested. Meanwhile, the operation method of concrete cantractometer is refined.

关 键 词：混凝土 收缩 试验方法 测量标距 测量长度
