    The current study has shown that the production of recycled concrete aggregates from waste concrete, has significant environmental benefits. It is suggested that governments may consider measures such as imposing higher taxes on production of crushed natural aggregates while keeping lower taxes for recycled concrete aggregates. Such measures would lead to reduction in consumption of natural

  • Concrete Production

    In the past decades, the demand for concrete production has been increasing along with the consumption of natural aggregates. The process requires large amounts of materials that significantly contribute to the global warming and environmental impacts. This study deals with the life-cycle assessment (LCA) of concrete production process

  • Mechanical behaviour of concrete made with fine recycled concrete

    This paper concerns the use of fine recycled concrete aggregates to partially or globally replace natural fine aggregates (sand) in the production of structural concrete. To evaluate the viability of this process, an experimental campaign was implemented in order to monitor the mechanical behaviour of such concrete. The results of the following tests are reported: compressive strength, split

  • Recycled Aggregates

    The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed. Recycling of concrete is a relatively simple process. It involves breaking, removing, and

  • Manufactured Aggregate

    The recycled-concrete aggregate has been satisfactorily used as aggregate in granular subbases, lean-concrete subbases, soil-cement, and in new concrete as the primary source of aggregate or as a partial replacement of natural aggregate. Recycled-concrete aggregate generally has higher absorption and lower specific gravity than natural aggregate. This results from the high absorption of the

  • How Concrete is Made

    How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
