Large quantities of energy and money can be conserved by recycling solid urban waste. While uses for recycled ferrous and non-ferrous metals are apparent, uses for the glass fraction have not been identified. As a result, a program to develop methods for incorporating waste glass into composites which can be used for construction materials was started in July 1976. Since that time tests to measure the properties of glass-polymer sewer pipe have been started. Field testing of full-scale specimens is also in progress. To date the results from compressive strength and three-edge bearing strength measurements indicate that the high strength properties are reproducible. The coefficient of variation is generally less than 10 percent. Hydrostatic test requirements can also be attained. Energy budgets and cost estimates are currently being made. Work accomplished during the period January 1-March 31, 1977 is described in the current report. |
