Fresno Farmers’ Market: Ornamental concrete tiles

6.000-square-foot ornamental concrete slab with special hand made fish-tail tiles. Each tile is about 15 inches long and 6 inches wide, in thin dense concrete about 1/2 inch thick. made by precasting 1/2" thick light blue fishtail tiles, cast on the ground with a blue pigment in the mix. To save money they were dropped into the slab, the same afternoon the slab was cast, when the concrete had been screeded off, and was setting up, just stif enough to support the tiles, and still plastic enough to let the tile sink in just the right amount. The technique generated a pleasant unevenness in the tiled surface.
