This paper presents the mechanical response of concrete composites subject to extreme loadings including blast. In general, the dynamic strength of the concrete was greater than the static strength of the concerete so the dynamic increase factor (DIF) was defined as a ratio of the dynamic strength to the static strength and greater than one. Since the DIF was a function of strain rate, it was hard to apply the DIF to the analysis and/or design of concrete. Therefore, the new
