Project Description
In May 2012, the FORTA-FERRO® macro synthetic fiber was used in a very large slab on metal deck project that provided a working surface for the 2nd-level order fulfillment operations for a large online retail store. Previous mezzanine projects had resulted in an unacceptable level of cosmetic cracking, and a high volume dosage of macro synthetic fiber was selected as a cost-effective potential corrective measure. The fiber was 2-1/4 “ long at a concentration of 0.5% by volume (7.5 Ibs. / cu. yd.), and used in over 237,000 square feet of 3-1/2” composite metal deck. The fiber-reinforced concrete was pumped over 300 feet in some areas in a 4 in. line, and pumped easily after minor pump-grate corrections were performed. To-date, only very few short, tight cracks have been reported from re-entrant corner stairwell openings, and cracking on the open deck has essentially been eliminated.
Update
Only very few short and tight cracks have been reported since the initial construction from re-entrant corner stairwell openings, and cracking on the open deck has essentially been eliminated.
Key Points:
- Superior Finish
- Extreme Durability
- Reduced Cracking
