Committee Mission: Develop and report information for the aggregates (except lightweight) used in concrete.
Goals: 1) Revise "Guide for Use of Normal Weight and Heavyweight Aggregates in Concrete" (ACI 221R); 2) Revise "Report on Alkali-Aggregate Reactivity" (ACI 221.1R); 3) Develop document on freeze-thaw durability of normal weight aggregates for use in concrete.
Documents Under Development:
• 221.1R (future): Report on Alkali-Aggregate Reactivity
• 221.XR: Freeze / Thaw Durability of Normal Weight Aggregate
• 221R: Guide for Use of Normal Weight and Heavyweight Aggregates in Concrete
