Although ACI 211 is considered the “Standard Practice” for proportioning concrete mixtures, there are other techniques also referred to in ACI 301, “Specifications for Structural Concrete” and ACI 318. In addition, there are techniques used in the industry for proportioning, evaluating and approving concrete mixture proportions. This presentation will include an overview and some examples.
