WEBGeneral Guidelines. Use no more cement than necessary for strength/durability. Minimize water/cement ratio. Maximize coarse aggregate size and content. Use mid-range or HRWR for slumps higher than 5 inches. Avoid entrained air for interior flatwork. Use normal set, retarders, accelerators as needed for set. How do we proportion a “good” mix design?

Factors Affecting Concrete Mix Design Strength
WEBThe mixing of concrete constituent materials i.e. cement, water, aggregates and admixtures in specified proportions will produce a concrete of adequate strength. The mix design strength developed for a given type of cement is dependent on the following factors: Water/Cement Ratio; Cement Content; Relative proportion of fine and coarse aggregates
