Concrete Cracking Theory

Introduction

  • Flexural Cracking
  • Early Thermal Contraction Cracking
  • Long Term Drying Shrinkage Cracking
  • Seasonal Thermal Contraction Cracking

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:

This presentation is aimed primarily at thin suspended slabs, but the basic principles can be applied to other forms of construction.
