| Summary: | The environment, natural resources, and waste recycling must all be preserved in today's world. One of the world's most serious environmental challenges is the toxic nature of electrical (E) waste. As a realistic means of disposing of E-waste and reducing the extraction of natural aggregate using E-waste as aggregate in concrete, hence reduces harm to the environment and aids in sustainable development. Therefore, in this study, the fresh and mechanical properties of mixtures with replacing coarse aggregate by nonmetallic printed circuit board (NMPCB) in volume ratios of 0%, 5%, 10%, 15%, 20%, 25%, and 30%. The experimental results indicated that the density, slump value, concrete compressive strength, flexural strength, split tensile strength, ultrasonic pulse velocity, and rebound number were reduced in various ratios by increasing the replacement ratio of NMPCB. These results may be attributed to the low strength, flakiness shape, and smooth surface of NMPCB particles compared to coarse aggregate. Moreover, the replacement of E-waste by up to about (10-20) % does not significantly reduce the mechanical properties. Therefore, it is a good alternative material for lowering aggregate usage, which lowers the cost of materials and is an eco-friendly way to dispose of E-waste. |
