Product details description
Chicken wire utilized for concrete reinforcement serves as secondary
reinforcement in slab-on-grade applications and crack control measures through
distributed tensile strength enhancement throughout concrete matrices.
Construction-grade mesh employs hexagonal woven patterns conforming to ASTM A809
specifications with wire diameters of 20-18 gauge providing flexible
reinforcement capabilities while maintaining workability during placement
operations. Material specifications include galvanized steel wire with zinc
coating weights of 0.1-0.2 oz/sq ft ensuring corrosion protection throughout
concrete service life, with mesh openings typically measuring 1-inch diameter
providing adequate concrete bonding and crack bridging capabilities.
Installation procedures involve placement at mid-depth in slabs 4-6 inches
thick, with proper lap splicing of 6 inches minimum ensuring continuous
reinforcement throughout concrete placement. The mesh reinforcement system
provides crack width control through distributed tensile forces, reducing crack
widths from 0.1-0.3 inches to less than 0.05 inches in properly reinforced
slabs. Applications encompass residential garage slabs, industrial floor slabs,
warehouse applications, and areas requiring crack control without primary
structural reinforcement requirements.
Engineering considerations include mesh placement spacing typically 12-18
inches on center, with proper elevation control ensuring mid-depth positioning
preventing settlement during concrete placement operations. Quality control
measures encompass wire gauge verification, coating thickness testing, and mesh
opening dimension compliance ensuring reinforcement effectiveness. Performance
characteristics include resistance to concrete placement forces, maintenance of
structural properties under freeze-thaw cycling, and durability against alkali
attack from concrete pore solutions. Construction advantages include lightweight
installation handling, flexible placement accommodating irregular slab
geometries, and cost-effective reinforcement for non-structural applications.
Material compatibility includes resistance to concrete alkaline environment,
proper galvanization preventing wire corrosion, and dimensional stability
maintaining reinforcement positioning throughout concrete curing processes. The
reinforcement system provides effective crack control and secondary
reinforcement for appropriate concrete applications while maintaining
construction efficiency and economic feasibility.
