Session: Cold Weather Concreting

July 22, 2026 from 11:00am to 12:00pm Central Standard Time

Without special planning, cold weather concreting can cause delayed concrete setting, finishing, and strength gain. If not properly protected, early-age freezing of freshly placed concrete can seriously damage concrete resulting in costly repairs and tear-outs. Learn how cold weather conditions affect both fresh and hardened concrete properties. Hear about cold weather specifications, protection, CFA’s research findings for casting walls in cold weather, and how to avoid cold weather concreting problems.

Learning Objectives: 

1. Identify how cold weather conditions affect fresh & hardened concrete properties.
2. Adjust mix designs & order concrete to minimize risks associated with cold weather concreting.
3. Evaluate delayed setting, concrete hardening, finishability & strength gain.
4. Design a cold weather placement plan to avoid problems & costly repairs.
