Committee Mission: Develop and report information on the proportioning of concrete mixtures.

Goals: 1) Revise and ballot ACI SPEC-211.1, "Selecting Proportions for Normalweight Concrete"; 2) Revise documents to include heavyweight concrete, submittal of concrete proportions, laboratory tests, and assessing aggregate gradation for proportioning.

Chair: Ezgi Wilson
