“…Nevertheless, after this initial period, the presence of polypropylene fibers leads to an improvement in the bending tensile strength of concrete, particularly when added at a concentration of 2.5 kg/m 3 . This improvement in bending tensile strength has been observed in comparison to reference concrete without fiber reinforcement [38,39]. Furthermore, concrete modified with the addition of polypropylene fibers has been found to exhibit better brittleness properties compared to reference concrete and even concrete modified with steel fibers.…”

We have fabricated the concrete reinforced polypropylene fiber with styrene-butadiene rubber latex bonding agent of concrete in different ratio. The prepared concrete employed with structural studies using FTIR and XRD spectra. An FTIR spectrum shows the important characteristics peaks of polypropylene fiber and styrene-butadiene rubber along with silica peaks. XRD pattern indicates that concrete crystal structure of three polymorphs such orthorhombic, triclinic and monoclinic phase. SEM image indicates that the above 10 wt % of polypropylene fiber causes small hairline cracks on its surface. It is found that the tensile strength increases with increase in different weight percentage of polypropylene fiber up to 10 wt %. This is may be due to the high compactness and reduction in porosity of the concrete block. It is also important to note that the water reduce admixture such as Polycarboxylates in required ratio’s significantly effects on capillary threshold by reducing 8-12 % of water results higher density of the concrete.

The scientific community is currently confronted with critical problems in providing a healthy world for future generations. The study for sustainable plastic recycling methods is difficult for a variety of purposes. Indeed, during the previous century, the widespread usage of plastic materials has resulted in vast amounts of long‐lasting waste that has remained largely unaddressed by effective collection and disposal policies. Packaging materials are responsible for the majority of this waste which also includes polypropylene materials. However, environmental concerns imposed a new trend in the previous decade that brought this research under focus, as seen by the growing number of linked publications. For the recycling of polymeric plastic materials, several chemical and mechanical methodologies have been proposed. Due to the low ultimate tensile strain of concrete, plastic waste fiber materials have been used in concrete in recent times as the reinforced concrete components often function with cracks during the serviceability phase. The bonding strength and stress variation during flexure, toughening effect of a hybrid combination of steel and recycled polypropylene fibers on high‐strength concrete are investigated. Polypropylene's compressive and tensile strength, good dielectric characteristics, and acid and alkali resistance have all been observed in various studies. Hence the current review focus on the past researches on utilization of recycled polypropylene in concrete for the enhancement of its physical and mechanical properties.

“…In addition, Cui et al 129–131 found that the pore structure of concrete was optimized by adding steel fiber, nano calcium carbonate, and multilayer graphene. Therefore, the selection of different aggregate gradations or the incorporation of different admixtures, such as steel fibers and polypropylene fibers, can affect the permeability of concrete, resulting in different depths of water penetration 132–135 . Although scholars have carried out permeability tests on concrete with different aggregate gradations, the effect of different water pressure magnitudes on its permeability has not been studied.…”

Compared with the ground service environment, the evolution of concrete performance under a water pressure service environment is quite complex with variable conditions. Because of the coupling effect of load and pressure, water has a special impact on the strength and deformation of concrete. Meanwhile, harmful ions usually react with the cement matrix as pressure water seepages into concrete, resulting in the reduction of concrete durability. Based on this, this study provides a comprehensive review of the strength, deformation, and durability of concrete under water pressure environment. It is found that microcracks in concrete tend to propagate and connect after exposure to water pressure, leading to a decrease in strength and deformation performance. The average loss rate of strength and elastic modulus increased by 12.15% and 10.97%, respectively, when water pressure increased by 1 MPa. However, the loading process of water‐confining pressure makes concrete more compact, where the static and dynamic mechanical performance can be improved. Besides, due to the enhancement of excess pore water pressure, concrete strength under a high strain rate increases by 61.79% compared to static load. The effect of water pressure increases the ability of the liquid to penetrate concrete, and corrosive ions trapped within the liquid and freeze–thaw caused by external temperature changes would further reduce the concrete durability. This study points out that static and dynamic loading characteristics and durability of concrete under multi‐factor coupling in a water pressure environment will be the future research direction. The summarized contents can provide guidance for construction and research of concrete engineering under a water pressure environment.
