| 摘 要： | 自密实混凝土具有降耗、环保、密实等优点，在工程结构中的应用日趋广泛，但自密实混凝土的收缩是影响其应用的主要因素。根据对36根自密实混凝土棱柱体进行的试验，对膨胀剂掺量等因素对自密实混凝土收缩性能进行分析研究，结果表明自密实混凝土掺人膨胀剂将延迟收缩变形的发展，膨胀剂掺入量会影响自密实混凝土的收缩性能。

| Abstract: | Self-compacting concrete has advantages such as lower consumption,protecting environment and compacting,which is getting more and more widespread application in the engineering structure.However,the shrinkage is the main factor for the application of self-compacting concrete.Expansive agent and other factors with regard to the shrinkage performance of self-compacting concrete were analyzed and investigated based on the 36 self-compacting concrete prism tests.The results show that the development of shrinkag... |
