What is the significance of interlocking in aggregates?

Interlocking in aggregates refers to the way individual particles fit together to create a more stable and cohesive mixture. This interlocking mechanism is crucial for enhancing load transfer and structural integrity in concrete. When aggregates interlock, they increase the mechanical interlocking among particles, which helps to distribute loads more evenly throughout the material. This results in a stronger and more durable concrete structure capable of withstanding various stresses and loads over its lifespan.

While uniform color distribution, overall cost reduction, and simplified curing processes are important aspects of concrete mixtures, they do not directly relate to the structural benefits provided by the interlocking of aggregates. The primary purpose of achieving interlocking is to ensure the mixture can support loads effectively and maintain stability under operational conditions, making it a key factor in concrete performance.
