The cast-stone terrazzo composition shall be composed of fine and coarse mineral aggregate and Portland cement or other suitable binder. The color of the aggregate and binder shall be such mix to produce the desired color. 2.1.2 Fine Aggregate. Fine aggregate shall be mar- ble chips, sand, stone, slag screenings, or other inert material with similar characteristics, and shall be well graded and pass a 1 ⁄ 4 in. (6.4 mm) screen. 2.1.3 Coarse Aggregate. Coarse aggregate shall be marble chips or other inert material with similar charac- teristics, and shall pass a 3 ⁄ 8 in. (9.5 mm) screen and retained on a 1 ⁄ 4 in. (6.4 mm) screen. 2.1.4 Portland Cement. The Portland cement used in the mix shall comply with ASTM C 150. 2.1.5 Suitable Binder. Other suitable binders must meet the performance requirements of this Standard. 2.1.6 Color. Cast terrazzo plumbing fixtures shall bemottledwhite,gray, orothercoloratthemanufacturer or consumer’s option. 2.1.7 Finish. All surface voids shall be filled and polished or troweled to match adjoining surfaces. Exposed surfaces visible to user shall be even, uniform and smooth, without pits or air holes, and free from all loose aggregate chips. After grinding, the surface shall be washed, cleaned, and sealed over the exposed surface of the product. All surfaces exposed to water during normal usage shall be sealed.
2.2.2 Sinks. Sinks shall be one piece-molded units. The bottom shall slope toward the drain. Waste fitting openings shall be sized to accommodate standard waste fittings unless the waste outlet fitting is manufacturer- supplied. 2.2.3 Service Basin. Terrazzo service basins shall be one-piece molded units. The floor shall slope towards the drain. A drain fitting for inside caulking to a 3 in. (76 mm) pipe shall be embedded into the fixture. 2.2.4 Wash Fountains and Lavatory Systems. Wash fountain and lavatory system bowls shall be one-piece molded units with the inside bottom of the bowl sloping towards the drain so as to provide continuous draining during use. All such bowls shall have a waste-fitting opening, the center of which is at the lowest point of the bowl. Waste-fitting openings will be sized to accom- modate standard waste fittings unless the waste-outlet fittingis manufacturer-supplied. Bowls shall have a min- imum capacity of 2 1 ⁄ 4 gal (8.5 L) per user. Circular and nonlinear units shall provide 20 in. (508 mm) of rim per user. Linear units shall provide 24 in. (610 mm) center- to-center distance per user section. 2.3 Warpage The maximum allowable warpage for all terrazzo plumbing fixtures as measured at top of the threshold and curbs shall be 5 ⁄ 16 in./ft (25 mm/m). 2.4 Drains and Strainers Drains and strainers shall meet the requirements of ASME A112.18.2/CSA B125.2, or ASTM F 409.
