Preparation of Lightweight Bricks Using Sewage Sludge

Abstract:

8,285 tons/day of sewage sludge was discharged in 2009. Our study investigated improving sewage sludge’s recyclability by making lightweight bricks from it. The bricks’ compressive strength, specific gravity, water absorption and so on were measured to evaluate its characteristics. Its compressive strength ranged from 1.11 MPa to 10.92 MPa (3-class clay brick, the Korean standard, is 10.78 MPa or more). Its highest compressive strength was obtained at the mixing ratio of SS:MBA:BFS:WA = 6:1:1:2, and its range of specific gravity was 0.73–1.02 g/cm3. Heavy metal did not leach from it. Therefore, sewage sludge can be prepared and used to make lightweight brick.
