摘要：
The influence of addition of fibrillated and monofilament polypropylene fibers to a cementitious composite mix on the tensile strength, flexural strength and ductility characteristics of the sample are being probed in this study. The study demonstrates that addition of fibrillated variety improves the strength of the samples both in tension and flexure in comparison to that of monofilament variety, whereas the addition of monofilament variety improves the tensile and flexural ductility characteristics of the sample. A combination of both these type of fibers improves the tensile strength and ductility characteristics along with improvement in flexural ductility with no significant improvement in flexural capacity.
