Abstract

Traditional mortar is a brittle material that functions well in compression but can undergo brittle failure under tensile pressure. The rise in mortar strength promotes mortars brittleness. Introducing fibers into cement-based composites is so popular to boost the tensile performance and mechanical qualities. The polypropylene fibers are typically utilized in cement-based composites, although much attention is not made on usage in cement mortar. The goal of this investigation was to evaluate the benefits of using polypropylene fibers in cement mortar. The utilisation of polypropylene fibers in cement mortar fits with the requirement for economic resources in building. The influence of polypropylene fibers (PPF)on cement mortar was studied with a focus on the impact of PPF content on the physicomechnical properties include workability, bulk density, compression and flexural strength of polypropylene fiber cement mortar, polypropylene fibers with 12 mm length were added in proportions between 0.5-1.25% at 0.25% interval .The 30 specimens were manufactured, poured into cubic shaped moulds for compressive strength test and prismatic moulds for flexural testing, and treated at 28 days before the tests. The outcomes reveal that the usage of polypropylene fiber provides an unmistakable enhancement in these attributes and hence the perfect amounts for this fiber have been taken into account. The outcomes demonstrate an improve in mechanical strength with increasing amounts of fibers in the cement mortar, The maximum compressive strength reached 42.96%, whereas the maximum flexural strength attained 51.85% following the incorporation of the highest fiber content, which is 1.25% volume fraction.
