ACI 224R-01 - Control of Cracking in Concrete Structures

Author: Reported by ACI Committee 224 | Size: 0.74 MB | Format: PDF | Quality: Original preprint | Publisher: American Concrete Institute | Year: May 16, 2001 | pages: 46

The principal causes of cracking and recommended crack-control procedures are presented. The current state of knowledge in microcracking and fracture of concrete is reviewed. The control of cracking due to drying shrinkage and crack control in flexural members, overlays, and mass concrete construction are covered in detail. Long-term effects on cracking are considered and crack-control procedures used in construction are presented.
Information is presented to assist in the development of practical and effective crack-control programs for concrete structures. Extensive references are provided.
