Quarry Tile Is Satisfactory for Powerplant and Pumping Plant Floors

摘要

A variety of tests were performed on quarry tile, portland cement-sand mortar setting bed, and jointing mortar to determine the suitability of these materials for use in principal floors of two large pumping-generating plants on San Luis, Central Valley Project. Four test panels were fabricated from materials similar to those likely to be used. Specimens core drilled from panels were tested in tension and compression. Shear bond strength was tested in accordance with Federal Specification SS-T-308b. Other tests performed included abrasion, impact resistance, and stain and ddiscoloration tests using oil, grease, acid, and wax. Test results, together with consultations with representatives from the tile manufacturing and tile setting industry, indicate that quarry tile installed by methods approved by the tile industry should provide a suitable floor for pumping-generating plants. The report contains nine conclusions based principally on results of laboratory tests. (Author)
