By using these materials they follow these steps.
Concrete mix ratio for driveway.
A standard concrete mix is 2 500 psi.
In areas with cold winters concrete mix should have a 6 percent.
General purpose concrete mix ratio 1 part cement 2 and a half parts of sand and 3 parts gravel.
That is because it is among the most versatile mix ratios regardless of what scale it is being used at.

3 parts stone or aggregates 3 parts sand.
To withstand the weight of vehicle traffic choose a concrete with a strength of 4 000 pounds per square inch for your driveway.
An overly wet mix can lead to finishing problems and a weak surface.
You can use this type of concrete mixture for most kinds of concrete works like paving driveways creating pathways and sidewalks and other general landscaping works.
Alter the materials as the strength properties of the concrete are inversely proportional to the water cement ratio.
What is the concrete mix ratio of 20mpa concrete.
Sand 882 3 kg.
517 pounds of cement or 234kg 1560 pounds of sand or 707kg 1600 pounds of stone or 725kg 32 34 gallons of water or 132l.

Mix water with the cement sand and stone which will form a paste that will bind the substances together until the mix.
Because concrete is permeable it will draw moisture from the ground that it rests on.
As such it can productively be used in a wide variety of weight bearing projects.
