Abstract: Use of high performance concrete (HPC) is extensively made in infrastructure projects world over for improved life expectancy, which in turn helps in sustainability of developments by delaying its replacement in future. It has been observed that many pre-stress concrete structures have shown distress in their early life due to lack of understanding of long term response which in turn is a function of creep and shrinkage properties of concrete used. This paper presents appropriate creep and shrinkage model for HPC on the basis of review of selected models from international codes/practice against the published experimental test results. Test data of creep and shrinkage for five different HPC grade have been used for this study. Four different existing creep and shrinkage prediction models, taht is, the ACI 209 R-92 model, the CEB FIP 2010 model, GL 2000 model and B3 model have been chosen for comparison with the test results. Seven different statistical criteria namely residual method, B3 coefficient of variation, CEB coefficient of variation, CEB mean square error, CEB mean deviation and Brook's error coefficient and deviation coefficient criteria have been used for comparison of the chosen models for error estimates, at different maturity periods of concrete ranging from early days to 1000 days. ¬© 2014, Universities Press (India) Private Limited.
