When designing concrete floors, one of the major issues discussed in Portland Cement Association and American Concrete Institute publication guides is the shrinkage potential of the concrete mixture. The shrinkage of the concrete is a deciding factor in an effective slab design. As it is dependent on the materials available, concrete shrinkage can vary throughout the world. A slab design that performs well using a low-shrinkage mixture may not work if a high-mixture is used. Therefore, a single design for high-performance floors is not possible. This session will discuss the influence of shrinkage and how it can be useful in determining the right design for each concrete project.
- Describe what concrete shrinkage is and why it is so influential to floor slabs.
- List causes for the wide range of concrete shrinkage
- Discuss ways to minimize concrete shrinkage in conventional concrete mixes
- Evaluate potential design solutions for when you cannot get low shrinkage concrete
