The Concrete Foundations Association has expanded its program offerings for the 2012 Summer Convention by adding another day (Thursday, July 26) on slabs.  We recognize that many of you are involved in the installation of slabs-on-ground whether it is basement slabs, driveways, sidewalks or commercial slabs and parking lots.  Constructing a quality concrete slab is a lot more complicated than simply putting concrete on a gravel base.  If you install slabs, you should do it correctly.

We have several great presentations lined up for this day of education.  Kim Basham, a regular presenter at the World of Concrete will be the primary presenter for the event.  He will cover “Crack Control”, “Finishing Exterior Slabs.” and “Finishing Interior Slabs,” as well as related topics on slab construction.  We will also have presentations on “Moisture Control in Slabs,” and “Fibers for Slabs”

Moisture Problems in Slabs

Moisture-related problems are said to cost the US Construction market upwards of one billion dollars each year in damage, repairs, and litigation.  Moisture Control in Slabs will encompass the problems associated with excess moisture and humidity from the ground, the science behind moisture vapor migration, a summary of the leading standards and industry recommendations, and a discussion on installation techniques

Finishing Interior and Exterior Slabs

To achieve high-quality steel troweled or broomed slabs, you must understand the finishing steps and the “window of finishability.”  Topics covered include:  how to identify the “window of finishability” and how jobsite conditions can either lengthen or shorten this window, how to achieve flatter floors, why premature finishing causes surface defects, why overworking the surface should always be avoided, and how to overcome the challenges associated with bleed rates versus evaporation rates. After this presentation, you’ll understand how to avoid surface defects, call-backs and expensive repairs caused by improper finishing.

Crack Control in Slabs

Nobody likes random cracks, especially in new concrete slabs on grade.  In this presentation, you’ll learn what causes out-of-joint dry/thermal shrinkage cracks.  More importantly, you’ll learn how to develop a crack control philosophy and design to minimize random cracking in slabs.  Hear about concrete shrinkage and restraints, tensile stresses, designing and installing contraction joints and load transfer across joints.  After this presentation, you’ll be better equipped to avoid and troubleshoot random cracking in slabs on grade.

Fibers for Slabs

This seminar will present basic information and engineering discussions on both standard-grade and second generation synthetic fibers for concrete.  Objectives of the presentation will include:

  • An understanding of the four most important fiber characteristics and how they effect performance in concrete.
  • Use of a 4-C’s fiber formula to objectively compare fiber types and brands;
  • Understanding the two basic performance levels of synthetic fibers: temperature/crack control reinforcement and structural property enhancing reinforcement; and
  • Determining appropriate real world applications for both levels of synthetic fiber reinforcement.

If you are coming for the summer convention, extend your stay forward a day – it will be well worth your while.

If you are local, you have two options – come for the day or come for the entire program.  CFA contractors are involved in a broad range of concrete operations and the scope of the Summer Convention reflects that diversity.  I’m certain you will learn something regardless of what segment of the concrete industry you are in.

  • 9:00 to 10:00
    Moisture Problems in Slabs – Bryce Skeeters, Stego Industries
