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.

“…The incorporation of SIF into concrete can be contributed to providing the same level of flexural strength as synthetic fibers such as polypropylene fibers as well as gaining ductility and flexural toughness to cement-based composite [52]. Besides, the inclusion of human hair fibers can contribute to enhancing the flexural strength of concrete slightly and decrease its production cost [20,53]. On the other hand, the incorporation of 2%MSF into RPC gave an increased rate in the flexural strength higher than that of containing1.5%MSF+0.5%SIF, 1.5%MSF+0.5%HHF, or 1.5%MSF+0.25%SIF+0.25%HHF.…”

The new production ofReactive Powder Concrete (RPC) has become an interesting topic due to the dramatic properties that such materials can give. Thus, this study has been prepared to observe the properties of RPC mixes reinforced with micro steel fibers (MSF) by the order of 2% volumetric fractions (vol.). As well, hybrid fibers from MSF, sisal fiber (SIF), and also human hair fibers (HHF) have been included in the RPC mix in the order of 1.5% MSF plus 0.5% SIF, 1.5% MSF plus 0.5% HHF, and 1.5% MSF plus 0.25% SIF plus 0.25% HHF, respectively. Besides, the inclusion of two different nanomaterials combination by 2.5% Nano glass powder (NG) and 2.5% Nano Iron slag powder (NS) was performed into that reinforced RPC. The preparation of these different RPC mixes was followed by testing them to investigate the performance of such RPC based on the properties of flowability, compressive strength, tensile strength, flexural strength, flexural toughness, and static modulus of elasticity. The results showed that the incorporation of 2%MSF increases the compressive strength, tensile strength, and flexural strength by 6.76%, 12.45%, and 14.34%, respectively, at 90 days. Whereas, the reinforcing of RPC by 1.5% micro steel fibers (MSF) with 0.25% sisal fibers (SIF) and 0.25% human hair fibers (HHF) rises the values of compressive strength, tensile strength, and flexural strength by 5.38%, 11.59%, and 14.05%, respectively, at age of 90 days. Moreover, the uses of nanoparticles as 2.5%NG with 2.5%NS in addition to 2%MSF increase the compressive strength, tensile strength, and flexural strength by 33.09%, 36.05%, and 43.68% at age of 90 days, respectively. The use of 1.5% MSF plus 0.25% SIF plus 0.25% HHF with the mentioned nanoparticles (2.5%NG and 2.5% NS) boosts the best performance by converting such concrete from brittle material to ductile material.

“…(3.09, 9.04%), tensile stress increased by (1.92, 6.57%), and (1.82, 2.73%), and elongation at break increased by (1.34, 5.13%) and (0.91, 5.19%), respectively [16], [17]. Hair and wave polypropylene fiber were used by [18], and it has been seen that hair fiber proves better strength characteristics than wave polypropylene fibers.…”

For a long period, materials like steel, jute, wood, etc. are been taken into practice for concrete fabrication. The reinforcement of concrete structures provides good stability and improves the mechanical properties of the material. The overgrowing population results in demand for infrastructures, which in proportion increases the production of concrete. To reduce the after effect of concrete production and prevent the use of raw materials, the utilization of waste elements as a substitution for concrete constituents is exercised by researchers to decrease the chance of degradation by construction pollution and landfilling of waste. The use of waste Human Hair Fiber (HHF) as concrete fabrication is a step forward toward sustainable construction. The current study has been performed to examine the effect of HHF reinforcement on concrete by determining the strength features of the concrete with human hair of lengths 20, 50, and 80 mm at 1%, 1.5%, and 2% addition of HHF by the weight of cement on. However, it was found that a 1.5% addition of human hair of lengths 50 mm and 80 mm shows the maximum compressive and flexural quality whereas, a 1% addition of human hair with 50 mm length as given the maximum 28 days tensile strength.
