This presentation addresses the proper application of empirical crack control measures into concrete masonry wall systems as presented in NCMA TEK 10-2D. It includes causes of cracking, use of control joints and horizontal reinforcement to minimize cracking, details and banding (mixing courses of clay and concrete masonry).
Learning Objectives:
- Causes of cracking in concrete masonry
- How to minimize cracking potential
- How to control cracking through the use of reinforcement and control joints
- How to maintain the fire resistance rating of a concrete masonry wall at a control joint
