Abstract
Many factors affect creep of concrete; this paper considers the adequacy of creep prediction models - B3 and Eurocode 2 (EC2) in formulating creep functions of CEM II made concrete. Existing predictive models employ different parameters in their approach to capturing the effect of binder types other than CEM I. Concretes formulated with CEM II at 0.5 w/b ratio were tested at three different ages for elastic modulus and compressive strength while complementary prisms were subjected to 1.0MPa compressive stress for creep monitoring. The experimental results were compared to predictions from models B3 and the EC2. Each of the models was modified by substituting the experimentally determined compressive strengths and secant moduli of elasticity at 3, 7 and 28 days into the relevant equations. Excellent correlations were found between the predicted basic creep and the experimentally derived total creep compliance functions. This confirms that, the coupled stress and shrinkage function behaves in a similar manner as the basic creep function.
