Testing the early-age shrinkage deformation of cement-based materials is the basis to estimate the risk of cracking correctly. In fact, there exists no uniform on the autogenous shrinkage test in China. This review analyzed the articles testing autogenous shrinkage with corrugated tubes based on the volume-to-length conversion coefficient, the time-zero of autogenous shrinkage, the characteristics of early micro-expansion, the friction between corrugated tube and ground, the sealing property of the end corrugated tube, the control of testing temperature and the testing apparatus. Some vague concepts in the existing research were discriminated when the corrugated tubes method was compared with other methods, giving some suggestions for the future application of the corrugated tubes method in China.
