Objectives:The intent of the study is to assess the strength and durability behavior of concrete specimens attaining micro fillers such as alccofine and zeolite and micro reinforcement in the form of polypropylene fibres. Methods: Polypropylene fibres were added in volume fractions of 0%,0.1%, 0.2%, 0.3% and 0.4%. The mechanical properties of concrete such as compressive strength, modulus of elasticity and flexural strength were obtained for concrete mixes with and without PP fibres through standard testing procedure. Some durability properties such as water absorption, porosity, sorptivity, acid resistance were also examined. Appropriating instrumentation has been adopted for making the measurements pertaining to the above parameters. Findings: Introduction of micro fillers and polypropylene fibres caused a significant effect on as compressive strength, modulus of elasticity, flexural strength, water absorption, porosity, sorptivity, and acid resistance. The results indicated that inclusion of polypropylene fibers exhibit maximum increase of 15.15% and 14.87% has been realized in the compressive strength of cube and cylinder, a maximum increase of 10.47% in flexural strength and 14.35% in elasticity modulus through the inclusion of polypropylene fibre. Novelty: The article reveals that inclusion of micro fillers and polypropylene fibre reinforced concrete in public spaces is a promising practice, since they are impacted by adverse environmental conditions, suffer surface degradation, and are the target of vandalism. It is clear that using concrete with improved characteristics will be advantageous.
