Abstract
Weight and Environmental concerns are two elements that have made the search for alternative materials of construction critical in today’s construction industry. The importance of finding a solution to the problem has given rise to the use of non-degradable materials. This study examines the challenges of making such material as polystyrene used in product packaging a part of the structural element in construction. Such adventure it is envisaged reduced the volume and number of landfill sites in Nigeria where air pollution arising from dump sites affects the health of citizens. To achieve this aim, Styrofoam was used as a partial replacement for coarse aggregate (granite) by volume. The replacement was carried out in varying percentages of 10, 20 and 30% Styrofoam concretes respectively with a concrete mix ratio of 1:1:2. The result obtained showed that concrete produced using Styrofoam as the alternative aggregate possess lesser values of compressive strength when compared with the control of conventional concrete without Styrofoam. The optimal percentage of a replacement for Styrofoam concrete was 10% with a compressive strength of 21.33 N/mm2 while the control concrete had a compressive strength of 33.26 N/mm2. The loss of strength of Styrofoam concrete is compensated by the reduction of the requirement for landfill sites and the attendant pollution generated while the concrete can be used for non-structural elements in construction.
