Aggregates for Concrete

For adequate consolidation of concrete, the desirable amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass). Rounded aggre- gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values.
