WHAT is Ready Mixed Concrete?
Concrete is a mixture of cementitious materials, water, aggregate, usually sand and gravel or crushed stone. There is a common misunderstanding that cement and concrete are one and the same. Cement is a powdered ingredient that provides the glue that binds the aggregates together in a mass called concrete.
