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.
found and the mix design requires adjustments to compensate for variations from the ideal conditions. The consistency of the mix, relative to the wetness or dryness, will affect the workability to a large degree. Do not increase the water content beyond the tolerance allowed in Specification 2461.3J without adjustment in the mi x design.
