Back to CC2 Phase II Single Slab

The single slab was placed on June 2, 2003. The slab was 15 ft. by 15 ft. (4.6 m by 4.6 m) by 11 inches (28 cm) thick. The cementitious mix contained 60% class “C” flyash. The experimental single slab was placed on an existing 20 ft. by 20 ft. (6 m by 6 m) by 9 ¾ inches (25 cm) thick concrete slab. Strips of construction paper were placed on the surface of the existing slab to act as a bond breaker between the new single slab and the existing slab.

The slab was wet cured for 28 days using burlap strips, timed soaker hoses, and plastic sheet coverings. The sides of the slab were coated with a sealer after the initial 28 day wet curing period. This action provided a simulation of the condition whereby the slab would be drying while being embedded among other slabs as it would have been in an actual test item. No constraints were placed at the boundaries, allowing for free curling movement. All coverings were removed after 28 day wet curing process, and the slab was allowed to dry for 113 days.
