Abstract:
PrimeComposite, a steel fiber reinforced concrete (SFRC) containing proprietary additives to control hygral shrinkage, provides significant reductions in CO2 emissions per square meter and improved performance over traditional slab on grade systems. This paper describes the development of the PrimeComposite system including the structural design approach, which is based upon full-scale mechanical testing results presented here. A typical PrimeComposite slabs on grade is 10 cm thick with single-casting (jointless) areas of up to 6500 m2. At this thickness, rack system loads of 140 kN (back-to-back leg loads) are safely supported.
