The basic composition of
concrete matrix is concrete,
sand, and gravel. Additional
components for the concrete
matrix are called concrete
admixtures which help alter the
chemistry for the concrete for
applications of strength, cold
weather, and concrete shrinkage. Calcium chloride has been one of concrete admixtures for a long time to lower the freezing point of concrete.
