Shrinkage, Creep and Other Concrete Properties
This chapter considers the shrinkage and creep formulae in MC2010 and its potential modification in accordance with the conclusions of the test results. The drying shrinkage defined in MC2010 is modified to avoid a discontinuity at higher levels of humidity, using a percentage humidity measured at a stabilized stage. The relations for creep and shrinkage predict the time dependent mean cross‐section behavior of a concrete member moist cured at normal temperatures for no longer than 14 days. When evaluating delayed strains to a greater level of accuracy, it may be necessary to modify the model parameters for creep and shrinkage by using experimental measurements. When considering temperature effects on delayed deformations, three aspects should be considered which includes an acceleration of the drying kinetic related to associated strains, an increase of the range of basic creep and potential effects on the maturity of autogenous shrinkage.
