In spite of their excellent material properties, the use of UHPCs is hindered by limited suppliers of this material and proprietary mixture designs. The lack of a systematic methodology to proportion the ingredients, including fibers, to achieve target mechanical properties is a major impediment for widespread application of UHPCs. The main goal of this research is to develop a systematic framework for mixture proportioning of strain-hardening UHPC (SH-UHPC) that explicitly applies the fundamental principles for achieving high compressive strength and tensile ductility. An innovative combination of experimental design and particle packing model is proposed to develop this framework. Experimental investigations were performed to understand the effect of the UHPC ingredients and their proportions on the mechanical and rheological properties of UHPC. These experimental investigations led to the discovery of key mechanisms, significance of ‘q’ in particular, which govern the material properties. An efficient and accurate method to determine the fiber-matrix bond properties is also proposed in this research. An innovative method to enhance the bond between the steel fibers and the cementitious matrix of UHPC is developed. The influence of mechanical properties of UHPC on the structural response of concrete-filled steel tube was also investigated.
