%X 采用非接触式电涡流位移传感器设计了自密实混凝土自收缩试验方法，进行自密实混凝土自收缩试验，考察粉煤灰单掺、粉煤灰与矿渣复掺、胶结料用量、水胶比对自密实混凝土自收缩的影响规律，并在试验的基础上提出自密实混凝土的自收缩计算模型. 研究表明，该模型能够准确地对自密实混凝土的自收缩进行有效预测，可供相关研究人员进行参考.<br>On the basis of the past autogenous shrinkage test methods and existing experimental conditions and objective factors，the test method of self-compacting concrete autogenous shrinkage is improved. Through the autogenous shrinkage experiment，the autogenous shrinkage rule of self-compacting concrete on single-doped ash，fly ash and slag re-mixed，cementitious material consumption，water cement ratio，is obtained，and an autogenous shrinkage calculation model of self-compacting concrete is put forward. The study shows that the autogenous shrinkage of self-compacting concrete can be effectively predicted by the model to reference for research personnel
