The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement the mix is a .50 water to cement ratio.

Calculate the surface area of your project in square feet. To calculate the square footage of a rectangular area, multiply the length times the width for the area. To find the area of a circle, multiply (pi) by the radius of the circle squared.

Concrete mix design may be defined as the art of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength durability as economically as possible.

The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of, which translates to 55 pounds of water for every 100 pounds of cement.

CONCRETE MIX DESIGN AND OPTIMIZATION Genadij Shakhmenko 1 and Juris Birsh 2 Riga Technical University, Department of Building Materials Azenes str. 16, LV 1658. SUMMARY Determination of ingredients of aggregate mixes is discussed as an important part of concrete mix design. Different types of "ideal" aggregate grading curves are presented in the work.
