“…The concrete mix lost about 50% of its strength only after replacing 5% of coarse aggregate with waste plastic (the strength dropped from 29.5 to 14.5 MPa) while increasing the replacement to 25% led to over 85% loss in the compressive strength (4.2 MPa with 25% replacement). These results agree with what other researchers reported [35,36,41,55,56]. This decrease could be due to the weak pond between the plastic aggregate and the cement paste since the plastic has a smooth surface which weakens the interfacial transition zone [37,39].…”

Flooding is one of the climatic change consequences that has become a dangerous threat to many coastal cities. Pervious concrete is considered a solution to decrease rainwater runoff and mitigate flood effects, as it allows water to percolate through the ground and prevent possible damage. Using waste products as aggregates in pervious concrete not only exploits waste materials and makes it valuable but also reduces the amount of this waste ending in the landfill or harming the environment, and it decreases the demand for natural resources. Infiltration rate test and compressive strength tests were conducted to investigate the effect of using waste plastic and/or recycled rubber as concrete coarse aggregates with different ratios (5%, 10%, 15%, 20%, and 25%) on the pervious concrete. The results showed that increasing the waste materials in concrete decreased the compressive strength for all ratios while increased the infiltration rate values.

“…Factors such as particle size grading, the shape of particles, the water-cement ratio, and the amount of plasticizer in the mix are directly related to the concrete workability. Various researchers have investigated and reported the influence of recycled and waste plastics as fine and coarse aggregates (recycled and waste plastic aggregates-RWPA) on the workability of concrete [21,[30][31][32][33]. Research findings have shown conflicting performances of concrete workability under the influence of RWPA, as demonstrated in Figure 3.…”

The abundance of waste plastic is a major issue for the sustainability of the environment as plastic pollutes rivers, land, and oceans. However, the versatile behavior of plastic (it is lightweight, flexible, strong, moisture-resistant, and cheap) can make it a replacement for or alternative to many existing composite materials like concrete. Over the past few decades, many researchers have used waste plastic as a replacement for aggregates in concrete. This paper presents a comprehensive review of the engineering properties of waste recycled plastic. It is divided into three sections, along with an introduction and conclusion. The influence of recycled waste plastics on the fresh properties of concrete is discussed first, followed by its influence on the mechanical and durability properties of concrete. Current experimental results have shown that the mechanical and durability properties of concrete are altered due to the inclusion of plastic. However, such concrete still fulfills the requirements of many engineering applications. This review also advocates further study of possible pre-treatment of waste plastic properties for the modification of its surface, shape, and size in order to improve the quality of the composite product and make its use more widespread.

“…However, the study showed that uneven incorporation of steel fiber would affect the fluidity and uniformity of concrete mixing and even result in fiber bonding, which eventually affects the reinforcement effect of mechanical properties" [7][8][9]." "Steel fibers efficiently increase the load carrying capability of slab & also allows the structure to behave more flexible.…”

Concrete is weak in tension and strong in compression which results in brittle failure. This is obviously unacceptable for any construction materials. Thus, concrete requires some type of tensile reinforcement to balance its brittle behavior and improves its tensile strength. Adding of fibers is one of the most prevalent techniques to enhance the tensile behavior of concrete. Fiber slows cracking phenomena and increases energy absorption capacity of the structure. Majority researchers focus on mechanical performance of fiber reinforced concrete. In this research, the influence of various dosages of steel fibers (0%, 1.0%, 2.0%, 3.0%, and 4.0% by weight of cement) is investigated on the mechanical and durability properties of concrete. Mechanical properties such as compressive strength and split tensile strength are studied at 7-and 28-days curing. To evaluate the durability aspects of each mix, various parameters such as water absorption, acid attack resistance, and permeability are investigated. Results indicate that strength was increased up to 2% addition of steel fiber and then reduced gradually. It also indicates that, durability parameter of concrete for example water absorption, permeability, and acid attack resistance considerably improved with incorporation of steel fibers at 2.0% incorporation of steel fibers. Therefore, it is recommended to mix steel fibers up 2.0% by weight of cement to achieved maximum benefits.
