Investigation of Mechanical and Impact Properties of High Performance Self-Compacting Composite Concrete
High performance self-compacting fiber reinforced composite concrete (HPFRSCC) are mighty and mighty materials that form a mixture of cement mortar and fiber. In this study, the mechanical and impact properties of these composite concrete have been empirically investigated. Various experiments were carried out on the samples, such as self-compacting concrete tests, compressive, splitting tensile and flexural strength tests, ultrasonic test and impact resistance test. The results of these experiments showed that steel fibers can have a negative effect on the self-compacting and cohesion properties of concrete, and have a positive effect on improving mechanical properties and impact strength of concrete, which has a significantly higher effect on impact resistance. In this study, the effect of two parameters of increasing the thickness of the slab and adding steel fibers to increase the impact strength of the slabs were surveyed and compared. The result of this study showed that steel fiber is a much more important parameter in increasing the impact strength of slabs .
