Abstract The accuracy of the equivalent age method on property prediction of mass concrete was evaluated for five mixture proportions and two kinds of curing conditions. The concrete specimens were cured using standard curing or matching curing based on adiabatic temperature rise test results. The results show that the calculated concrete properties predicted by the equivalent age method were much higher than the measured data for concrete prepared using matching curing. Thus, the equivalent age method cannot accurately predict the properties of mass concrete.
