Effect of date palm and polypropylene fibers on the characteristics of self-compacting concretes: comparative study

This article presents the results of a comparative experimental study on influence date palm fibers to replace polypropylene used as reinforcement in self-compacting concrete (SCC). Indeed, use makes it possible reduce plastic shrinkage concrete. Date have mechanical characteristics (tensile strength and elasticity modulus) largely sufficient fibers. The natural has several advantages, they are natural, renewable, no affect environment require little energy for their transformation, unlike synthetic In this study, fiber is control material material. obtained show that two types decrease fluidity compressive but increase flexural shrinkage. delay appearance cracks more than guarantee best SCCs fresh hardened state
