An Experimental study on concrete reinforced with Fibrillated Fiber

This research paper presents experimental study on the performance of polypropylene fibrillated fiber reinforced concrete. The properties of concrete with and without fibers have been compared in this paper. In this experimental work three different dosage of fibrillated fiber (0.05%, 0.10%, and 0.15% by volume) were used. Important concrete properties i.e. slump, bleeding, settlement, compressive strength, flexural behavior, drying shrinkage, abrasion resistance, and splitting tensile strength have been studied in this experimental work. The following important observations for the concrete containing fibrillated fiber were found: i) Drastic reduction in slump of concrete; ii) Reduction in settlement of concrete; iii) Insignificant effect on compressive and splitting tensile strength; iv) Drastic reduction in drying shrinkage; v) Increasing trend in flexural strength with increase in fiber dosage; indicating several technical benefits on addition of fibrillated fiber in concrete.
