Sie Of Fine Aggregate For Concrete

Aggregates for Concrete. The proper selection of aggregates for use in concrete mixtures is critical to long term concrete performance. Aggregates generally occupy 60% to 75% of the concrete volume and strongly influence the concrete’s fresh and hardened properties, mixture proportions, and economy.
