Study and experimental investigation on performance self-compacting concrete using different type of fibers

Nowadays, the construction industry over the entire world is looking for more economical construction materials. In addition, the existence of self-compacting concrete is facing brittleness problems due to their high binder content and low aggregate amount. On the other hand, the fiber is widely known to enhance the properties of concrete by bridging the crack width and hence, overcoming the brittleness problem in concrete. The goal of this paper is to evaluate the effect of different fibers on the properties of self-compacting concrete such as stand chopped basalt (SCB) and polyvinyl alcohol (PVA) fibers. The experimental work conducted were fresh tests, such as slump flow, slump T₅₀ and V-funnel, while the hardened properties were compressive, flexural and bond strength. The results gathered from the empirical work showed that the fibers had a slight effect on the fresh properties and the compressive strength. While the flexural and bond strengths increased with the addition of the fiber content.
