What is the most common type of concrete?
Standard ready-mix concrete
is the most common form of concrete. It is prepared for delivery at a concrete plant instead of mixed on the construction site, which guarantees the quality of the concrete. This type of concrete can provide a structural function, as well as an aesthetic or decorative finish.
