properties of concrete using pebbles as coarse aggregate

  • Aggregate in Concrete The Concrete Network

    But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. . Both gravel and crushed stone produce quality concrete.
