“…The increase in the compressive strength of RPC specimens has been obtained due to the use of nanoparticles and fibers, which also leads to a tensile strength increase. The development of tensile strength of cementitious matrix by incorporation of nanoparticles has been noticed by several researchers [48][49].…”

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.

“…In the 19th century, asbestos strands were used as a piece of cement and by the 1960s, many sorts of fiber, like steel fiber, and glass fiber, built strands, for example, polypropylene filaments were used for concrete fabrication. Fiberreinforced cement (FRC) has started making its place or noteworthiness in various domains of normal advancement applications, especially where the requirement for repairing, increments facilitated strength is more [4], [5].…”

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.

“…However, RPC concrete is relatively new in Indonesia and the strength achieved is around 60-75 MPa without heat curing. Moreover, research with regard to green-substitution materials for RPC components has been performed and demonstrated favourable results in improving mechanical properties of concrete [6][7][8]. Therefore, the objective in this study is to gain knowledge about the impact of ferronickel slag as replacement for quartz sand in RPC.…”

This paper aims to evaluate mechanical behavior (compressive and flexural strength) of reactive powder concrete (RPC) with ferronickel slag (FNS) as quartz sand replacement. Standard laboratory tests were performed i.e. sieve analysis to determine the particle size distribution of the FNS, slump and density tests as well as compressive and flexural tests on the RPC. Promising results were obtained in this study. An increased consistency and density were observed upon increasing the FNS content. The utilization of FNS could lead to a compressive strength value of 86 MPa at 28 days. A higher strength enhancement in the early curing days (7 days) was observed than in the longer curing days (28 days), when FNS mixes were compared to reference mixes. The flexural strength result demonstrated two different phenomena at two different ages, where there was a slight rise at 7 days and relatively no increment at 28 days when FNS mixes were compared to the reference mixture.
