coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ- ence the concrete’s freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.). Coarse aggregates (Fig. 5-2) consist of one or a com
