Summary
"Waste glass and waste plastic combine to form a major portion of nonbiodegradable, solid waste. These waste products aggravate the already too serious problem of environmental pollution. Hence, a means is sought of utilizing this waste in the construction industry, thus solving two problems simultaneously - that of beautifying the environment, and of procuring inexpensive building materials. Extrusion is not an uncommon process as far as the manufacture of original products is concerned. Hydrostatic extrusion is a modification of the process wherein a billet or slug of some material is forced to flow through a die under the influence of a hydrostatically applied force. Upon completion of this process, the extrudate is formed into the desired cross-sectional shape, while achieving a significant increase in its strength. The earlier portion of this thesis describes the design of the equipment and the material selection for conducting the experimental work. A distinctive feature of the design is a shrink-fitted pressure vessel capable of holding 100,000 pounds per square inch of pressure. The two main operations in this research, compaction and extrusion are described in detail. Because of the complicated nature of the process, there are several variables that affect the strength of the finished product. As the product strength would be a prime consideration in an application in construction work, the effect of each one of these variables on the extrudate strength has been examined. It was difficult to test the extrudate by conventional methods. Therefore, it was necessary to adopt a few special techniques to serve the purpose. Following all practical considerations, the conditions for obtaining an end product of optimum strength have been described. This product compares favorably with the performance as well as the cost of high strength concrete"--Abstract, leaves i-ii
