Crushed Mosaic As Coarse Aggregate In Concrete

  • Recycled glass as a partial replacement for fine aggregate

    a replacement for coarse aggregate. The results from these tests demonstrated that the presence of larger glass particles caused excessive expansion and cracking of the concrete specimens, resulting in compromised structural integrity. These effects can be attributed to the strong reaction between the alkali in cement and the reactive silica in glass (Johnson 1974). In order to minimize

  • Aggregates U.S. Concrete

    Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and Portland cement, form the necessary ingredients in concrete. Aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of fine materials that could cause the deterioration of concrete.

    Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate. The use of recycled concrete, crushed to propersize concrete aggregate, has also demonstrated successful performance. Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good
