In our market, most of the mixes involve adding more Portland cement which affects the strength of the concrete. We typically use a 6 Â½ bag (of Portland) mix that has a compressive strength rating of 3500 psi for sidewalks and 4000 psi for driveways.
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 materials together until the mix hardens. The strength properties of the concrete are inversely proportional to the water/cement ratio.
