# Concrete Mix designs?

Could anybody give me a math theorem used to mix generic concrete designs.

I.E Length x breadth x height type theorems

Thanks

When you are refering to the mix design you are talking about the ratio of , and type of materials used to batch the concrete.

Concrete is a mixture of:

Portland Cement, or some other sort of cementitious material

Sand

Aggregate

Water.

When you mix these components together the cement reacts with the water to form a crystalline structure that bonds the aggregate together.

Your formula is similar to the one used to figure out the volume of the concrete so that you can order the proper amount of material.

The primary design parameter for concrete is the strength. This is measured, in the United States, in pounds per square inch (PSI). Depending on what the concrete is going to be used for you can order concrete with a strength as high as 9,000 PSI. There is even stronger concrete.

Different additives can add to the workability and strength of the concrete.
