A concrete slab is a structural feature, usually of constant thickness, that can be used as a floor or a roof. A slab-on-ground is supported on the subsoil and is usually reinforced with reinforcing bars or welded wire mesh. A suspended slab (or structural slab) spans between supports and must be reinforced to resist bending moments calculated from statics based on the magnitude of load and ...
1.1.2 Preconstruction meeting—Construction of any slab-on-ground or suspended floor or slab involves the coordinated efforts of many subcontractors and material suppliers.
Placement of welded wire reinforcement (WWR) in a slab-on-ground Q. I’m looking for clarification regarding placement of welded wire reinforcement (WWR) in a slab-on-ground floor in a warehouse. Does ACI provide recommendations? A. ACI 301-20 provides placement requirements for WWR.
This guide 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 ...
A. Saw cuts, also called relief cuts, should be timed carefully to control cracking and maintain the integrity of the slab. According to ACI 302.1R-15, saw-cutt
Acceptable concrete cracking Q. What is considered as acceptable concrete cracking in cast-in-place foundation walls and slabs per ACI documents? My company is the concrete contractor on a large warehouse project, and I want to discuss the potential for cracking with the contractor and the owner. A. Concrete cracks are possible on any project, so it’s wise to set reasonable expectations for ...
