Finite Element Method
Earth is becoming more and more polluted as a result of the unrelenting growth of plastic garbage in land surface. Also, plastic wastes are regarded as the most hazardous of the wastes produced in today's society because they take a long time to biodegrade and account for 85% of all garbage produced globally. However, the use of these plastic waste products in the building sector can help to alleviate the strength of the concrete structures while lowering the current environmental issues. Hence, in this research aggregate waste plastics were added to the concrete mixture to increase the strength of the concrete. In which aggregate waste plastics are added to the concrete mix in three different types of structures like cube, cylinder and beam which are then checked for its mechanical properties using compressive test, split tensile test, and flexural test respectively. Finally, the strength of concrete at various plastic proportions with three different structures under varying loading conditions is investigated using Finite Element Method (FEM) in Abaqus software and the results are discussed and the optimal specimen of the concrete mixture are determined. The result obtained showed high compressive, splitting tensile, and flexural strength values of concrete since coarse particles are replaced with plastic in amounts of 10%, 20%, 30 % and 40% which outperforms traditional mix that have higher percentages of more than 40% plastic waste, indicating the worst-case scenario in mechanical properties.
