What is a Concrete Aggregate? (with pictures)

Feb 24, 2021  Sand is a common example of a fine aggregate in concrete. In order for aggregate to be effective, it must be strong. Weak aggregate materials will weaken the resulting concrete, which is not desirable. Aggregate must also be hard, so that it keeps its shape without deforming in the concrete.
