The main focus of this research is the composite comparison of steel fiber, polypropylene fiber and basalt fiber as it is a new category of hybrid fiber reinforcement in high performance high volume flyash concrete. Also many other researchers have studied incorporating individual fibers in high volume flyash concrete to improve the mechanical properties.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.
