Project Cinco – Georgia-Pacific
Green Bay, WI

7.5 pounds of macro fiber

2024 WRMCA Industrial Concrete Design Award, WI
The 305,000-square-foot industrial facility in West Salem used more than 14,500 cubic yards of ready-mix concrete for interior slab-on-grade, foundations, parking lot paving, and site concrete.
The interior floor mix was designed for 4,000-psi at 28 days with a maximum shrinkage of 0.40. It incorporated Type 1L cement, Class C fly ash, #4 and #67 coarse aggregates, natural sand, a mid-range water reducer, and 7.5 lbs. of macro fibers per cubic yard, with a water cementitious ratio capped at 0.45 to further control shrinkage.
A superflat slab area was required to meet the owner’s ASRS system specifications. This section was successfully placed as a single 35,000-square-foot pour spanning more than 160 feet. The project also included a fiber-reinforced mezzanine topping slab.
