Coarse aggregate testing is essential to evaluate the quality and suitability of aggregates used in concrete and construction projects. The tests typically include assessments of particle size distribution (gradation), specific gravity, water absorption, crushing value, impact value, los Angeles abrasion value, and aggregate impact value. These tests determine the strength, durability, and resistance to wear and tear of the aggregates, ensuring they meet industry standards for use in concrete mixes. Proper testing of coarse aggregates helps prevent issues such as excessive porosity, segregation, or failure under load, ultimately contributing to the longevity and safety of the structures.
