Ultra High Performance Fiber Reinforced Concrete (UHPFRC) is a concrete type with superior mechanical properties and of a relatively high tensile strength. The tensile stressstrain characteristics of UHPFRC are highly affected by the mixture design and the curing regime. In the present study, an extensive experimental investigation has been conducted with direct tensile tests on a number of specimens that contained different percentages of steel fibers and different cement types were applied. Also, various curing regimes were investigated. Different models depending on the steel fiber amount were proposed for the simulation of the stress-strain and the stress-crack opening response of UHPFRC, while the fracture energy was also calculated for the different fiber contents. Finally, the effect of fiber content and curing time on the variation of the experimental results are discussed.

Undoubtedly concrete is the most versatile and widely used construction material. It is the material of choice with strength, performance and durability. This study aims at utilization and to ascertain the suitability of saw dust ash as a partial replacement of cement, glass powder as a partial replacement of fine aggregate and rubber tyre pieces as a partial replacement of coarse aggregate in normal M30 grade concrete. Initially, all trial combinations were casted by replacing binder, fine aggregate and coarse aggregate at a varying rate of 2 to 10 %. The replacement percentage of binder giving maximum strength is chosen and is fixed accordingly for further studies. Thereafter, the percentage of coarse aggregate and fine aggregate were changed from 2 to 8% to arrive at an optimum mix having maximum compressive strength. The strength performance of these concrete with normal concrete mix is investigated and findings are reported.
