Analysis of Mechanical Properties of Concrete using Plastic Granules as Coarse Aggregates

This study presents the development and application of mathematical models to analyze the mechanical properties of concrete incorporating waste plastic granules. Specifically, the research focuses on compressive strength and split tensile strength of concrete mixtures where Low-Density Polyethylene (LDPE) granules are used as a partial replacement for natural coarse aggregates. LDPE waste, sourced from post-consumer plastic, was introduced in varying proportions of 0%, 20%, 30%, and 40% by volume. The study aims to evaluate the influence of these substitutions on the mechanical performance of concrete and to develop predictive models for strength characteristics. The results contribute to the sustainable management of plastic waste and provide insights into its potential for use in eco-friendly concrete production.
