Stochastic theory for fracture of concrete materials is applied. The fracture process can be described not only under monotonically increasing load but also under time-dependent loading conditions. Theoretical predictions are compared with earlier published data. Special accent is placed on the effect of rate of loading on the mean strength and corresponding variability. Specimens of high strength mortar, low strength mortar, lightweight and normal concrete were tested under compressive and bending load. The experimental results materially verify the theoretical concept.
