What reinforcement bars are used in concrete outdoor trash cans to prevent cracking?

Concrete outdoor trash cans require proper reinforcement to prevent cracking and ensure long-term durability. The most commonly used reinforcement bars include deformed steel bars (rebar), welded wire mesh, and fiber reinforcement. Deformed steel bars, typically grade 60 rebar with a minimum diameter of 3/8 inch, provide primary structural support against soil pressure and impact forces. These bars are strategically placed in both vertical and horizontal orientations throughout the concrete structure. Welded wire mesh, often made from galvanized steel, offers secondary reinforcement to control shrinkage cracks and distribute stress evenly. For additional crack resistance, synthetic or steel fibers can be mixed directly into the concrete. The reinforcement should be positioned approximately 1.5 inches from all surfaces to ensure proper concrete coverage and prevent corrosion. Proper bar spacing of 6-8 inches in both directions creates an effective grid system that withstands temperature changes, ground movement, and daily use. Regular inspection and adequate concrete cover are crucial for maintaining the integrity of these reinforced structures in various weather conditions.
