In recent decades, disposal of dry precipitate have been an important problem of sewage treatment plants due to environmental restrictions. Some investigations performed on application of these materials in construction materials especially concrete mix designs. Dry precipitate is regarded as the residue produced by the wastewater treatment process, during which liquids and solids are being separated. The constituents removed during treatment include grit, screenings and precipitate. The dry precipitate is by far the largest in volume, it is handling methods and disposal techniques are a matter of great concern. To Study the compression behavior of concrete by replacing of 0, 5, 15 and 20% in M25 grade of concrete to analysis this thesis on effect of concrete at various category tests with respect to compressive strength, flexural test and tensile strength at different stages of curing 7 and 28 days will be analyzed.
