Concrete Cracking – Theory

There are numerous causes of cracking in concrete, but most instances
are related more to concrete specification and construction practices
than by stresses due to induced forces.
The four primary causes of cracking that the designer can help to
prevent are:
• Flexural Cracking
• Early Thermal Contraction Cracking
• Long Term Drying Shrinkage Cracking
• Seasonal Thermal Contraction Cracking
This presentation is aimed primarily at thin suspended slabs, but the
basic principles can be applied to other forms of construction.
