This paper shows the results obtained from an experimental study to evaluate a basic creep model. In this study, four different mixture proportions were placed, and tests on the specimens for autogenous shrinkage and basic creep were conducted with respect to age and stress level. The primary test variable was the water/cement ratio (w/c). From this research, it was found that for low w/c concrete, as well as at an early age of normal-strength concrete, a significant difference exists between apparent basic creep (including autogenous shrinkage) and real basic creep (excluding autogenous shrinkage). Furthermore, creep strain was not directly proportional to the applied stress level after one day. It was also discovered that when the current basic creep model that includes autogenous shrinkage is used in creep analysis, considerable errors as well as some computational problems may result. We therefore recommend modifying the equations of the current basic creep model with respect to autogenous shrinkage. (C) 2006 Elsevier Ltd. All rights reserved.
