What is the Aggregate Crushing Value (ACV) test used for?

The Aggregate Crushing Value (ACV) test is primarily utilized to evaluate the resistance of an aggregate to crushing under a gradually applied load. This property is crucial because it helps predict how the aggregate will perform in various construction applications, particularly in road pavement and concrete. A lower ACV indicates a stronger aggregate that can withstand significant pressure without breaking, which is essential for ensuring the structural integrity and longevity of built projects.

Understanding the performance of aggregates under load provides insight into their potential durability and suitability for specific applications, supporting engineers and builders in material selection to ensure safety and reliability in construction projects. This test emphasizes the importance of aggregate strength and its direct impact on the quality of manufactured concrete and road surfaces.
