Abstract:

Ribbon Technology Corporation's use of steel fiber reinforced concrete in the construction of their new manufacturing and office facility in Gahanna, Ohio. Cost savings are obtained by labor savings and the reduced volume of material. In the construction three different lengths of steel fiber were used. The three inch Xorex material was used for the major structural elements in the construction. Two inch fiber was used for slab on grade and one inch was used in applications where gunning was required. The strength and toughness of the concrete increases with the fiber length while the ease of handling decreases. In all cases one hundred pounds of fiber per cubic yard was used for the concrete mix design. Several major first established on this program were: tilt wall construction with 100% steel fiber concrete; barrel vault roof construction using sprayed concrete techniques; a 100 ft dome with a raised tension ring design.
