Concrete Mix Ratio | What Is Concrete Mix Ratio | Types of

This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.. Mixing water with this cement, sand, and aggregate will form a paste that will bind the materials together until the mix hardens. This strength properties of the concrete are inversely proportional to the water-cement ratio.
