Optimizing concrete with custom polymer blends

The aim of this study is to develop a novel concrete composite using a mixture of low-cost rubber, Kevlar fibers, lightweight expanded polystyrene (EPS) and fire resistant nylon fibres. The goal is to create concrete that is stronger, lighter, fire-resistant and has insulating properties. A number of concrete blends were formulated using different percentages of the selected polymers. These blends were tested for compressive strength, split tensile strength, and density. Based on the findings, it can be concluded that incorporating those polymers would drastically improve the mechanical properties of concrete while reducing its weight. Some blend ratios achieved ensured optimal mechanical performance of the various polymer composite concrete and proved the feasibility of designing low-weight, resource-efficient concrete composites with varying applications in construction.
