why concrete cracks-withpics

strength of concrete is less than its compressive strength, the concrete bends to its breaking point. Homeowners who place large recreational vehicles or dumpsters on their driveways are more likely to see this type of cracking (See Figure 11). Driving heavy vehicles off the edge of a slab creates a similar type of crack. (See Figure 12).

Evaluating Cracking in Concrete - Bluey Technologies

Evaluating Cracking In Concrete PROCEDURES WHY CRACKS FORM IN CONCRETE STRUCTURES 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.
