The Effect of Ethylene Vinyl Acetate Replacement as a Fine Aggregate on C-25 Concrete Properties

Abstract

As construction engineering evolves throughout time, so does the requirement for raw material manufacture. Each year, around 25 billion tons of concrete are produced worldwide. The modern construction industries require enormous amounts of natural raw resources used to make concrete. As a result, the widespread use of these raw resources will result in the release of greenhouse gases, which may contribute to the acceleration of global warming. Another significant issue is the disposal of plastic waste, which has become a major environmental issue. This research examines the use of EVA plastic waste as a partial replacement for fine aggregate in C-25 concrete. Furthermore, the primary goal of this research is to analyze the properties of concrete, such as workability, compressive strength, and durability, in the partial replacement of fine aggregate. Portland Pozzolana cement, fine aggregate, ethylene vinyl acetate waste, and coarse aggregate were used in this study. Slump tests, compressive strength tests, water absorption tests, and permeability tests have all been accomplished. The overall sample size for the slump test was ten cubes, while the total sample size for the compressive strength and durability tests was fifty cubes, yielding the average. The percentages of replacement were 5%, 10%, 15%, and 20%, with a mix ratio of 1:2.17:2.68 cement, fine aggregate and coarse aggregate respectively. According to the findings, workability increased as the percentage of Ethylene Vinyl Acetate replacement increased, and compressive strength increased up to 10% Ethylene Vinyl Acetate replacement and decreased beyond that. Durability tests such as water absorption and permeability, in contrast to strength and workability, decline as the EVA replacement percentage increases. The study suggests more investigation into the influence of Ethylene Vinyl Acetate on reinforcement rebar in reinforced concrete
