Abstract
This paper presents the preparation of ash from sewage to be used in a concrete mixture for the slabs preparation. The ash was used in the mixture in 1.39, 2.78 and 4.17% by replacing an equal amount of sand. The slabs were prepared from this concrete mixture and the features were evaluated. The values of compressive and flexural tensile strengths of the studied slabs, having 4.17% ash at 28 days, were 54.3 and 9.7 MPA. The values of water absorption of slabs with 4.17% ash were 2.4% with water impermeability grade W10 (G2 grade). The values of concrete resistance to air penetration, and concrete air permeability at 4.17% ash content in the slabs were 14.1 s/cm3 and 0.070 m2. The abrasion resistance was slightly higher than the control. All these values confirmed that the prepared slabs with 4.17% ash content were of the highest quality.
