ACI 224R-01 PDF

Cracks detract from the appearance of concrete structures, and may indicate major structural problems. ACI 224R-01, Control of Cracking in Concrete Structures, covers the principal causes of cracking and also recommends crack-control procedures. The document also discusses the long-term effects of cracking. ACI 224R-01 is a revision of 224R-90. The updates include:

Discussion of fracture mechanics;

More information on controlling cracking caused by drying shrinkage;

Revised information on crack-width predictive equations, cracking in partially prestressed members, anchoragezone cracking, and flexural cracking in deep beams;

Crack control for concrete overlays, including fiber reinforcement and polymer-modified concrete; and

More extensive information on the structural consequences of cracking in mass concrete.
