Summary on Grant Application Form |
|
Initially, three standard HSC mixes (Fcu=80, 100 and 120 N/mm2 will be developed and for each mix the optimum/maximum practical fibre (steel and polypropylene) contents will be determined. In parallel with this development in the material area, the final arrangements for a new fracture/relaxation test (which is an indirect tensile test) will be confirmed. Thereafter a detailed study of the fracture/relaxation characteristics of the standard HSC mixes will be carried out, including specifically determining strength, fracture toughness, and post-cracking toughness. Finally a two-stage analysis of the experimental data will be carried out. One area of analysis will focus on developing suitable equations to represent the three material properties of E, strength and fracture toughness which can be used directly in FEA. The second area of analysis will concentrate on developing a method of determining the true long-term fracture toughness of concrete via the data gathered in the relaxation tests. The proposed programme is timely and brings together a number of current international research developments with applications in the analysis of failure (including shear failure) of dams, fixings in concrete, and high performance concrete.
