This module is based on articles from Concrete International magazine. They are intended to provide design and construction professionals with basic information about curling in concrete slabs. The articles present information about moisture and temperature gradients, shrinkage and expansion mechanisms, recommendations to reduce or control curling, and much more.

1. Understand how subbase conditions affect curling;
2. Recognize how slabs respond to relative humidity;
3. Describe how slab construction can affect moisture-sensitive floor coverings; and
4. Explain why the method and duration of curing of concrete slabs is important.
