Utilization of Sludge from Majis Waste Water Treatment for the Partial Replacement of Nature Fine Aggregate in Concrete
Keywords:Sludge, Concrete, Sand, Replaced, Finer.
This experimental investigation is to utilize the sludge waste as a replacement of natural fine aggregate. We can introduce a sustainable construction material which is proved to be an alternative for waste disposal, helping out to free from environmental pollution. By replacing the natural fine aggregate of sludge waste it helps us to save our nature. Per day for construction site, we are using a large quantity of natural fine aggregate. This study reviews various attempts that have been made to use sludge waste as the partial replacement of fine aggregate. The fine aggregate is partially replaced by a trial mix of 5%, 10%,15%,20%,25% and 30% with sludge waste .Then fresh concrete and hardened concrete is prepared by the partial replacement of fine aggregate. This process is to be done by dry condition. The mechanical and physical properties of the concrete after replacement is to be tested in the laboratory and the results are compared with the ordinary concrete. The comparison of results shows that the replace of 20% sand by sludge waste shows more compressive strength than that of the ordinary concrete with sand as fine aggregate. From the result we can understand that if the sludge contains finer particles the strength of the concrete will further increase.
