Grandma's Concrete Recipe

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).

Aggregate size| Concrete Construction Magazine

2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller sizes. 3. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand.

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.
