Concrete Mix Ratio With Grade and Usage Area

The ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture. A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the
