Análise da influência da variação do formato dos agregados graúdos nas propriedades físicas e mecânicas do concreto

Abstract

Concrete is a widely used and well-understood material in the construction sector across the country. Its properties in both fresh and hardened states are key reasons this construction method has remained prevalent over the years. Therefore, studying the characteristics of the concrete mixture is of great importance, as it allows for maximizing the strength and durability of structures. This study aims to determine the influence of the shape of coarse aggregates on the physical and mechanical properties of concrete. The development of this research will be crucial for identifying the most suitable shape to enhance the characteristics of structural concrete. The shapes chosen for this study were cubic and lamellar, as they show the greatest discrepancy in results according to existing literature. The methodology to obtain results involved performing physical and mechanical tests on concrete specimens made with coarse aggregates previously sorted by shape. The results of this study show that the ideal aggregate for concrete mixtures is the cubic shape, as it positively impacts the test results, particularly in compressive strength for hardened concrete.
