    Mar 01, 2021  Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete Particle size divides aggregates into two categories: fine and coarse Most fine aggregates are sand and contain particles smaller than 3/8
