Summary on Grant Application Form |

The research involves a series of experimental and theoretical studies. The experimental studies are designed to (i) express the workability of HPFRCC mixes in terms of the fracture toughness of the mix; (ii) quantify the evolution of damage during strain hardening using a special tensile specimen geome3try that has a large area where the tensile stress is uniform and well defined; (iii) study how the distribution of steel fibres is affected by the mixing and compaction procedures using the CT imaging technique; (iv) check whether the optimum HPFRCC mixes (point (b) below) reach the predicted mechanical properties; and (v) investigate the potential of two HPFRCCs for the retrofitting of damaged RC beams. The theoretical studies are aimed at (a) refining the constitutive relations of HPFRCC in the light of the experimental studies (i) - (iii); (b) formulating and solving mathematical optimisation problem of maximising the t4ensile strength and toughness simultaneously using the constitutive relations as constraints; (c) producing a software package that allows optimum HPFRCC mixes to be tailored to the requirements of the user; (d) developing design guidelines for the retrofitting of damaged RC beams with HPFRCCs that ensure the beams are made durable and strengthened and that in the event of failure the response will be ductile.
