ACI360R-10 presents information on the design of slabs-on-ground, primarily industrial floors. It addresses the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. 

Design methods are given for unreinforced concrete, reinforced concrete, shrinkage-compensating concrete, post-tensioned concrete, fibre-reinforced concrete slabs-on-ground, and slabs-on-ground in refrigerated buildings, followed by information on shrinkage and curling. Advantages and disadvantages of these slab design methods are provided, including the ability of some slab designs to minimize cracking and curling more than others.

ACI360R-10 (Chapter 6.2 - Load Transfer Mechanisms) states that “joint and crack stability measurements below 0.25 mm for joints or cracks subjected to lift truck traffic with small hard wheels will have good service life”.

The patented PD3™ design features a tapered and sleeveless plate dowel that provides the world’s best performance in limiting joint deflection to provide superior joint stability. The PD3 Dowel Cradle provides the highest deflection control tolerance in line with ACI Standards recommendations to limit joint spalling, facilitate load transfer and provide the lowest risk of restraint to ensure the best serviceability outcome for the slab design.
