摘　　要：探讨了混凝土早期自由收缩和约束收缩的实验方法,分别对自由收缩、环形约束收缩、轴向约束收缩、板式约束收缩的试验原理、试验方法、实验装置、适用性等方面做了较详细的分析和评价,对促进相关标准的制定,以及为结构早期裂缝控制和耐久性研究提供参考。The test methods for measuring shrinkage of concrete at early age are discussed, especially on mechanism, procedure, equipment and applicability for each type of shrinkage, such as non - restraied, ring restrained, uniaxial restrained and two - dimensional restrained. That will supply the references for compiling the related standards, controling the early cracking of structures and carrying out the research on the durability of concrete.
