“…This behavior can be confidently predicted as a result of the enhanced concrete surface and higher compressive strength. This result agrees perfectly with what has been found in the literature [11][12][13]…”

“…However, when pressure is applied to inclined surfaces, the force is split into two vehicles, with only the normal exerting a significant influence on the surface. This is consistent with the findings of Rawaa H. Ismaeil et al [13] and [15], which used the horizon and pg.92 four degrees of flow inclination (0, 30, 45, and 60). For all investigations, the seven-days age of concrete was used.…”

Significant volumes of non-biodegradable solid waste are related to industrial activity in Iraq, with waste plastic being one of the most notable. 24 samples were used in this study to test the effectiveness of recycling waste plastic to make concrete. Four different ratios of waste plastic from both green and conventional concrete were used as a partial replacement for gravel: 0%, 30%, 60%, and 100%. All of the concrete combinations were tested at room temperature. These tests include compressive strength and abrasion resistance. The compressive strength was determined by molding 36 cubes. In this study, concrete mixes were cured for 3, 7, and 28 days. The apparatus created in the Construction Laboratory of the Civil Engineering department at Wasit University was used to measure the rate of concrete erosion by directing a high-velocity jet of a water and sand combination at concrete samples. A determination was also made on the impact of the impingement angle. Using two distinct angles (45 and 90) with the horizon, experimental estimations were performed. The results of the experimental studies showed that the flow inclination angle of 45 with the horizon can achieve the highest rate of erosion, while the flow inclination angle of 90 with the horizon can achieve the lowest rate. Additionally, the results showed that erosion decreased as the plastic percentage increased with age. This study confirms that recycling waste plastic as a gravel substitute in concrete offers a promising solution to lower material costs and address some of the issues with solid waste that plastic presents.
