This presentation addresses the proper application of empirical crack control measures into concrete masonry wall systems as presented in NCMA TEK 10-2C. 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).
C205– 61 slides – 1 hr. LU/HSW)
In this presentation you will learn:
• 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
