Introduction and literature review -- Experimental methods -- Results and discussion -- Conclusion and recommendations. The Kohler Company manufactures a wide range of kitchen and bathroom fixtures around the world. The Kohler Company only produces products that are the best possible quality; all less desirable products become waste products. All waste products are collected in a Kohler-owned landfill at a rate of nearly 3,300 metric tons of pottery cull per month. Some portions of this waste are currently being used as a sub-base layer for infrastructure projects. If pottery cull waste is not used, it eventually is buried in the landfill. The purpose of this paper is to determine if pottery cull can become a viable substitution for fine and coarse aggregate in concrete. All pottery cull used in this experiment was pre-crushed, by the Kohler Company, to fine and coarse aggregate sizes. Concrete cylinders were made using various mix designs in accordance to ASTM C192. Mix designs included the following materials: water, cement, class F fly ash, natural coarse limestone, sand, coarse pottery cull, and fine pottery cull. Along with these mix designs, two control mix designs were made that included no pottery cull aggregate substitutions. In all other mix design samples, a portion of coarse natural limestone and sand were replaced by coarse and fine pottery cull, respectively. Pottery cull replaced these natural aggregates at 15, 35, 50, and 100 percent levels using the volume replacement method described in ACI 211. All concrete cylinders were then tested using ASTM C39 to determine the compressive strengths. The results of the experiment proved that pottery cull is an adequate aggregate replacer for maintaining the necessary compressive strength of concrete. It is recommended that further tests be analyzed for adverse freeze-thaw conditions and for alkali silica reactions. In addition, abrasive durability must also be assessed.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .W87 2011 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
