Abstract:
Various attempts have been made to incorporate waste materials in plain cement
concrete to reduce the weight of waste materials on national landfills and the economic
strain on the building industry. This research focuses on improving the mechanical
properties of concrete by treating the recycled aggregates with cement slurry and adding
polypropylene fibers in it. The Splitting tensile strength and compressive strength tests
were tested using the appropriate equipment. The use of cement slurry has improved the
compressive strength by 20% and the splitting tensile strength was by 2.5%. The use of
cement treated aggregates along with of polypropylene fiber has enhanced the compressive
strength by 28% and the splitting tensile strength was by 15%.
As a result, both the compressive and tensile properties of the recycled aggregates
concrete were enhanced by treating of recycled aggregates and addition of polypropylene
fibers, making the study effective in exposing the possible use of waste materials in
concrete production industries for environmental, economic, and value-added benefits.
