Ontario heavyweight Innocon Readymix has set what by Concrete Products records is a new North American volume record for a continuous self-consolidating mix placement. Dispatching 510 truckloads from four Toronto-area plants, the producer delivered 5,700 yd. of Agilia brand SCC for the foundation of the 55-story Four Seasons Yorkville Hotel. The 13-hour, late-November pour saw trucks feed the hoppers of a centrally located boom pump and five static placement pipes around the foundation perimeter. Placement peaked at about 525 yd./hour for mixes designed to reach 8,700-psi (60Mpa) compressive strength.
Agilia is a proprietary SCC of Lafarge North America, which operates Innocon as a joint venture with Essroc Canada. The project bests a continuous SCC placement benchmark–5,000 yd. in 24 hours–Chicago’s Prairie Material Sales set in September 2005 for the foundation of the 92-story Trump International Hotel & Tower’s core. The use of SCC versus conventional mixes afforded contractors productivity gains through faster placement rates and reduced labor requirements tied to finishing ease.
