Aurora pharmaceutical chose to reinforce their concrete floors with FORTA-FERRO fibers in their new state of the art greenhouse in Edmonton, AB. The total size of this slab-on-ground project is
73,164 cu m and FORTA-FERRO 54 mm long macro synthetic fibers were used. Because of the column grid and the interference caused by the continuous trench drains, the distance between joints were greater then normally specified. In this case, engineers chose to use fibers throughout the concrete in a minimum of 3.5 kg/cu m to obtain the best results. In addition, special attention to saw cut locations and bar reinforcement at re-entry corners were required because of the interaction of the long drains. The fibers are also useful in providing greater resistance to plastic shrinkage cracking and service-related cracking. By using FORTA-FERRO macro synthetic fibers, the owners achieved a durable greenhouse floor with a superior finish.
- Reduced Shrinkage Cracking
- Increased Durability
- Extended Joints
