The Concrete Industry’s Super Bowl

The World of Concrete 2026, held January 20-22 at the Las Vegas Convention Center, is more than a trade show; it is the annual barometer for the health of the concrete industry. For professionals focused on independent floor testing, WOC is where the science of slab drying is debated and defined.

Key Focus: Sustainable Mixes and Drying Times

This year, the buzz is undeniably about carbon reduction. As manufacturers introduce new pozzolans and admixtures to lower the carbon footprint of concrete, the chemistry of the slab changes. These “green” concrete mixes often exhibit different moisture retention properties compared to traditional Portland cement mixes. This presents a challenge for General Contractors: does the standard ASTM F2170 relative humidity test behave differently in these dense, eco-friendly slabs?

We expect the technical sessions at WOC 2026 to address the calibration of moisture probes in these new environments. If you are specifying sustainable concrete, you must ensure your testing agency is aware of the potential for prolonged drying times.

Technological Integration

Another trend to watch is the integration of in-situ sensors during the pour. While these sensors provide real-time data, they require independent verification to ensure accuracy before flooring installation. IFTI advocates for a third-party validation process to confirm sensor readings against standard concrete moisture testing protocols.
