### GRADE OF CONCRETE And their type of Grade - …

GRADE OF CONCRETE. Concrete of Grade is a mixture of Portland cement, water, and coarse and fine aggregates. It consolidates into a hard mas because of a stone reaction called hydration between cement and water. Proportioning a concrete mix for a given purpose is thus the art of obtaining a suitable ratio of the various ingredients of concrete with the required properties at the lowest cost.
