SCMs are used as replacement for cement, and since they have a very small particle size, they reduce the permeability of concrete, which is good. Fly ash is the most common SCM and it improves finishability, although it tends to slow the set time, especially in cold weather. SCMs can be used to replace as much as 40 of the cement in a mix.

Aggregates Cement

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.
