This course covers various aspects of curing as a part of the concrete construction project. Wet curing concrete has long been the standard to maintain moisture in slabs to hydrate and densify concrete and bring it up to strength. Two different hydration-enhancing products will be discussed: one applied externally during early finishing, and the other applied as a replacement cement product that offers improved internal curing properties.This course also details field experiences using the maturity method to measure concrete strength gain more accurately over different curing periods. Case studies will be presented on how to use maturity method probe equipment to perform successful maturity method tests, as will current research on how traditional wet-curing methods affect slab moisture gradients in ways that can result in curling.

The contents of this course include four recorded presentations from the ACI 2015 Fall Convention:
1. Integral Trowel Cure and Polished Floors: Introducing and Defining ITCP by Jason Barnes, Green Umbrella, Sheridan, AR
2. Drinking Water Treatment Residual as a Cement Replacement with Internal Curing Properties by John T. Kevern, University of Missouri—Kansas City, Kansas City, MO
3. Investigation on the Impact of Curing on the Long-Term Curling of Concrete from Drying by Tyler Ley, Oklahoma State University, Stillwater, OK
4. Using Maturity to Measure the In-Place Strength and Effectiveness of Curing by Frank A. Kozeliski, Kozeliski Consulting LLC, Gallup, NM

1. Describe the process and advantages of applying an internally troweled and cured polished concrete (ITCP) as curing occurs on slabs-on-ground.
2. Explain the process of reusing drinking water treatment waste material as an alternative cement filler, its material characteristics, and possible benefits to concrete placements.
3. Identify the equipment needed to measure in-place strength of concrete using the maturity method and the advantages of using the maturity method to measure concrete strength.
4. Understand how moisture strain gradients, wet curing, and subsequent drying affect slab curling.
