3 MIX DESIGN PROPORTIONING

An example of proportioning a mix design through use of this form is detailed in Table 3.1. The contractor establishes the initial parameters for a mix design and serves as the starting point for subsequent proportioning calculations. The initial step in proportioning the mix design is to calculate the water content per cubic yard of concrete.

Concrete Mix Design Just Got Easier Giatec Scientific

Feb 25, 2020  Concrete Mix Design. Concrete mix design is often mistakenly referred to as “cement mix design.” However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design.
