Abstract

Wheeled traffic has the potential for inducing large compressive and shear stresses in concrete for industrial floors. The authors look at the performance of industrial concrete floors taking into account the principles of contact mechanics and the influence of the hardness and abrasion resistance of the concrete. Concrete floor specimens were tested for abrasion resistance. The effect of the inclusion of metallic surface hardeners, liquid hardeners, and macro-fibers is reviewed. This paper evaluates the various issues related to floor capacity and performance under moving wheel loads and intends to provide good engineering recommendations for safe working designs of industrial concrete floors subjected to moving loads on casters and wheels.
