Concrete slabs aren’t that simple these days and at the 2016 World of Concrete you can see some of the most exciting new developments in equipment and materials live at the Concrete Slabs Showcase in the Gold Lot.
Creating a High-Gloss Concrete Slab without Polishing
In recent years, there has been research on how to efficiently create a polished concrete floor. One innovation has been to combine placing, power-troweling, and curing to create a serviceable, durable, and flat polished surface with equipment most concrete contractors already own — without a polishing machine. This demonstration will show how concrete contractors can begin to refine a slab’s surface during initial placement and take it to completion. Sponsored by Multiquip
How to Use a Roller Screed on a Curve
Placing concrete on a curve with a large radius can be difficult. Contractors often add finishers for the placement process to keep at the desired production rate. Using a roller screed can minimize crew size without sacrificing efficiency and helps ensure that the fresh concrete is struck off with minimum working. This demonstration will teach contractors to do more with less. Sponsored by Lura Enterprises
How to Use Vibration to Smooth Concrete Surfaces
Using a special tool that combines common finishing techniques with the benefits of external vibration, concrete contractors can efficiently level concrete slabs. This compact, lightweight cordless vibrating unit easily interchanges with most finishing tools, including edgers, screeds, bull-floats, jointers, and fresnos. Daily demonstrations at 1:30 pm.

How to Restore a Decorative Concrete Slab Surface
Removing discolored or flaking acrylic sealers from decorative concrete surfaces can be difficult. In this demonstration, contractors will learn about a new repair procedure that removes the sealer without damaging the hardened concrete. This simple blanket removal system is rolled on and then allows the acrylic sealers to be peeled off to reveal a surface ready for a new decorative treatment.

How to Efficiently Install an Effective Vapor Barrier
Vapor barriers are a key element in a slab-on-ground detail for moisture control. When properly installed, vapor barriers contribute to the quality of the slab and its service life. Attendees who participate in this demonstration will learn about the current industry standards regarding this construction material and how to properly install a vapor barrier.

Pervious Concrete Live
Research results are now making their way into the codes and standards that govern pervious concrete placement. The four current ASTM standards pertaining to pervious concrete testing will be demonstrated and explained by experts each day at WOC using pervious concrete mixed at the demonstration site. Small-scale placements (stepping stones) will also be molded to show “right” and “wrong” pervious mixes. Sponsored by Lura Enterprises and Cemen Tech
