Indianola Wellness Center, Indianola, IA is a community recreation and wellness facility that is owned by the City of Indianola and operated by the YMCA of Greater Des Moines. The building is a two story structure with a total building area of approximately 62,000 square feet. Forta Ferro, a macro-synthetic fiber system was approved as an alternate to the specified welded wire fabric (WWF).  Originally, the project specified W2.9 x W2.9 6x6 WWF in the 4” thick slab-on-grade, 3” thick topping slab over hollow core precast panels, and composite metal deck slabs.  WWF is difficult to position properly in the 4” thick floor slabs and 3” topping slabs.  Forta Ferro fiber reinforced concrete provides “top to bottom” reinforcement & allows for faster, more efficient construction and improves safety because WWF requires additional labor, gets in the way of concrete crew and equipment, and presents tripping hazards.  Everyone involved was pleased with the superior performance and ease of placement of Forta Ferro reinforced concrete.  Cameron Mitchell Inc. was the concrete contractor and Liberty Ready Mix was the concrete supplier.  DE Fiberworks provided the Forta Ferro product information and recommended dosage rates for the concrete applications and was approved by Tometich Engineering, the project structural engineer.

Concrete is widely recognized as an extremely versatile, cost-effective construction material?

 

Concrete is widely recognized as an extremely versatile, cost-effective construction material. Yet it is also beset with some drawbacks that are inherent to its composition.  By generally accepted engineering standards, concrete is relatively brittle and lacks ductility.  Intertwined with these problems is concrete’s propensity to crack in both its plastic (early-age) and hardened (long-term) state.  Early-age cracks are microscopic fissures caused by the intrinsic stresses created when the concrete settles and shrinks over the first 24 hours after being placed.  Long-term cracking is in part caused by the drying shrinkage that transpires over time.  In either case, these cracks can jeopardize the overall integrity of the concrete and not allow it to maintain – or possibly ever attain – its maximum performance capability.

 

This is the basic reason reinforcement in concrete is required.  Irregular cracks are unsightly and difficult to maintain but generally do not affect the integrity of the concrete.  Joints in concrete slabs are simply pre-planned cracks that are created by forming, sawing, or tooling.  Concrete slabs that are designed for serviceability typically use reinforcement such as deformed reinforcing steel bars (rebar) or welded wire fabric (WWF) to hold cracks tight.  The primary function for the reinforcement is to maintain aggregate interlock for load transfer and improve joint stability.  Rebar and WWR do not inhibit the formation of cracks, but if properly positioned provide reinforcement once a crack has developed.  Fiber reinforcement can provide the same function, is distributed throughout the cross-section of the concrete and distributes the stresses attributed to shrinkage throughout the panel making the joints much more stable. This distribution of fibers provides a totally reinforced cross-section of concrete and changes the way the concrete works.
