Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. ... Generally, flat and elongated particles are avoided or are limited to about 15 percent by weight of the total aggregate. Unit-weight measures the volume that graded aggregate and ...

At a ready mixed concrete plant aggregates are typically stored in a bin or a stockpile. The process of taking a sample of aggregate that is truly representative of the nature and condition of the aggregate in the stockpile, bin or transfer point is called aggregate sampling. ASTM D75 is the standard practice for sampling aggregates.

2.3 Aggregate Types. Aggregates can be classified based on several criteria. They can be separated into light, heavy, or normal aggregates if their unit weights are taken into account. Aggregates are also classified in fine aggregate (sand) or coarse aggregate (gravel) when particle size is considered.
