Abstract: The properties of UHPFRC mainly depend on the selection of ingredients with special curing and pre-compression techniques. In this project report, various proportions of materials, curing regimes and materials adopted by many researchers are discussed with special emphasis to the selection of materials as this forms the basis for proportioning of UHPFRC mixtures. The significance of this concrete is that the compressive and flexural strength is 5-10 times greater than the conventional concrete which is an indication of the improved performance of cement matrix interface achieved by various authors. In India very few works have been reported in this field and mass application of these special concretes to practice can be brought about only after rigorous R and D works. Studies were already been done by Advanced Materials Laboratory, CSIR-Structural Engineering Centre(CSIR-SERC), Chennai, to develop various UHPFRC mixture proportions by using indigenously available materials and study the properties of these concretes for their application in practice. Currently Concrete with grade 200MPa has already been developed. In this research work the focus has been given to replace the sand with copper slag in the UHPFRC mix. Other ingredients include cement, silica fume, quartz powder, and micro steel fibers.
