| This thesis is primarily concerned with the issue of the usefulness of waste glass. Currently, some of the waste glass generated in New York City is recycled into asphalt, but the rest is treated like any other solid waste material and thrown away into the landfills. Research done in this thesis used waste glass mixed with fresh concrete to observe the effect of recycled crushed glass on the tensile and compressive properties of concrete.; Following the testing procedure specifications from American Standard of Testing Materials (ASTM), the following results were concluded. For compressive strengths on average, glass increased the compressive strength of concrete from 2790 psi to 3500 psi an increase of 25.4%. For tensile capacity on average, glass increased the tensile capacity from 700 psi to 740 psi an increase of 5.7%.; Due to the fact that waste glass increases the strengths of concrete, this solution can be a viable option instead of disposing of the glass into landfills. Possible benefits are as follows: less glass is thrown away saving landfill space, the use of fewer natural aggregates (which are the components of concrete) saving our natural resources, and less labor is used by not shipping raw materials from distant places to where glass is available saving time and money. |
