Concrete Cracking – Best Practices – Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete. Cracking of concrete flatwork is natural, expected, and accepted. However, cracks may affect appearance, performance, and maintenance costs. This presentation will discuss the various types of concrete cracks and how to best minimize their occurrence. Learning Objectives: 1. Understand the different types of cracking in concrete. 2. Understand what causes concrete to crack. 3. Understand how to evaluate the difference between structural cracks and cosmetic cracks 4. At the conclusion of the presentation, participants will know how to minimize concrete cracks.
