Title: Sensitivity of the Models for Predicting Shrinkage of Concrete

Keywords: relative humidity; sensitivity; shrinkage; strength; type of cement; type of curing
Abstract:The purpose of this study was to conduct a sensitivity study on shrinkage prediction of concrete utilizing the ACI 209 (1), GL 2000 (2), B3 (3), and CEB MC 90-99 (4) models. The sensitivity of a prediction model is function of different parameters utilized in the equations describing the model. The influence of changing input parameters on shrinkage prediction was investigated. The study reveals that the change of relative humidity will result in similar sensitivity for different shrinkage models. The autogenous shrinkage component in the CEB MC 90-99 was found to be most sensitive to strength change at 28 days. The GL 2000 was found most sensitive to cement type while the B3 model was found to be most sensitive to specimen size and type of curing. In general the B3 was the most sensitive model while the ACI was the least sensitive.
