The world is facing a major challenge on ways to manage the waste synthetic materials that are potentially polluting the environment. So, by 2040 it is estimated from the total synthetic textile products that will be produced, the accumulated synthetic textile waste will be more than 73.77 %, if recycling of waste may not be managed by novel technology in different sectors. Hence, this is a great challenge coming to the world if it is not effectively recycled mainly to be used in the construction sector which covers a broad area. However, detailed critical review is needed to gather different authors result on waste synthetic fiber effectively utilized in construction materials like in a concrete. So, the present study reviewed, the effects of waste synthetic fibers specifically, which are covering many numbers of synthetic materials; polyester, nylon, and polyethylene replacement on the physical, mechanical, durability, and microstructural properties of concrete. As the review of most researchers indicates, reinforcing the waste synthetic fibers in the concrete by 0.1–1% to the weight of cement reduces workability, improves compressive, flexural, splitting tensile strength, and enhances durability. Specifically, adding around 0.5 % doses to the volume of the concrete makes good resistance to water absorption, chloride ion penetration, acidic attack, elevated temperature resistance below 600°C, and lessen concrete content hence, cost effective compared to the control concrete mixture. Besides these, the employment of waste synthetic fibers makes dense microstructure, consequently minimizes the crack occurrence and propagation.
