Abstract
Concrete is a fundamental construction material that is continually evolving to enhance its performance and sustainability. This research explores the potential of incorporating natural pumice powder and polypropylene as partial substitutes for cement in M20-grade concrete. The aim is to assess how these alternative materials influence concrete properties and sustainability. Through a comprehensive evaluation, the study provides valuable insights into improving the characteristics and environmental impact of concrete structures. This experimental study examines properties such as split tensile strength, compressive strength, and flexural strength of concrete specimens after curing periods of 7, 14, and 28 days. Concrete mixes with varying proportions of pumice powder (5%, 10%) and polypropylene (5%, 10%), as well as their combinations, are meticulously prepared and tested. The results indicate that adding pumice powder and polypropylene positively affects the strength properties of concrete, with some mixtures performing better than conventional concrete. The analysis reveals the underlying mechanisms contributing to enhanced strength, emphasizing the potential of these materials to boost the durability and long-term sustainability of concrete structures. These findings contribute to ongoing efforts to develop eco-friendly and highly durable concrete, promoting advancements in construction engineering.
