a study had been made for the development of High Performance Concrete using mineral admixtures such as Flyash, Silica-fume and Metakoalin along with steel and Polypropylene fibers. In this connection series of concrete cubes,
cylinders and beams. were casted with various mix proportions were tested as per IS 516-1959, IS 5816-1976 for getting
Strength Characteristic of Concrete The compressive strength, strength of the plain concrete specimens without any mineral
admixture & fibers have been compared with that of compressive-strength of composite concrete made up of mineral
admixtures & fibers The addition of fly-ash, silica-fume & Metakoalin influences the overall behavior of this concrete, while
the post-cracking residual strength is increased by the addition of steel fibers into the mix of 6 sets of concrete specimens
were carried out, the main parameters that are varied are mineral admixtures additions, fiber-volume, water-binder ratio
etc. Due to the addition of mineral admixtures & fiber volume into the mix, it gives very good performance & improves the
strength characteristic of concrete.
