Jul 11, 2016  4 Concrete Mixing Proportions: Concrete is a mixture of Cement, Coarse Aggregate, Fine Aggregate, and Water. Concrete sets in as few as 10 hours and continues to harden and cure as long as moisture and unhydrated cement are present. However, most of the increase in strength occurs within a few weeks. Usually the concrete mixture is cast with a steel reinforcing, forming a composite
