Grandma's Concrete Recipe HowStuffWorks

In modern concrete, a variety of materials help make up aggregates, including sand and various sizes of gravel and crushed stone. Aggregates are divided into two categories based on particle size: fine aggregate, which is 0.2 inches (5 millimeters) or smaller, and coarse aggregate as large as 1.5 inches (38.1 millimeters).

2014-7-31  Coarse aggregates, less than 50 mm (2 in.) in size, cost about half as much as the cement in concrete. The larger aggregates leave less room that must be filled with cement paste so they reduce the total water required in the mix. To avoid pop-outs in exterior concrete, the designer should specify crushed limestone aggregate where it is available.
