The Forms of Concrete. measurement is detailed in the CCAA Data Sheet Tolerances for Concrete Surfaces. Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water.When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid structure. Classes of Concrete 4.
