Factors to consider when selecting aggregate including size, shape and color considerations.
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.
Answer: This all comes from ASTM C 33, “Standard Specification for Concrete Aggregates.” First, there's really no difference in this context between stone and gravel and aggregate. In C 33 there's a chart showing the grading requirements for different sizes of coarse aggregate from #1 to #8.
