The concrete pouring of this slab was performed in a single day within a uninterrupted 13-hours of concrete placement to prevent cold joints. This 320 cubic meters of concrete was made with 2,350 kg of Xypex Admix C-500, silica fume and polypropilene fibers. Part of the water of the concrete was replaced with ice, and cured with 200 kg of Xypex Gamma Cure in order to minimize cracking. The biggest challenge was the preparation of this fluid roofing formwork that was shaped with pieces of polystyrene EPS, with 6 m x 8 m and an average around 1,000 kg.
