Designing a Lightweight Structural Concrete Mix| Concrete

Concrete Mix Design - The Best Concrete Mix - The Concrete

Sep 17,  · Using the ACI 211.1 method, here is an abbreviated run-through on how to design a mix: Choose the target slump. Choose the maximum aggregate size—remember that the larger the better for reducing shrinkage and curling. Estimate the water and air content using ACI 211.1 Table 6.3.3. Select the water-cement ratio.
