Abstract

The study examines the effects of incorporating sewage sludge ash (SSA) and treated sewage water on the strength and durability of concrete, aiming to evaluate their viability as sustainable alternatives in construction materials. Sewage sludge is burned at a high temperature of 800°C to produce SSA, which is analyzed for its chemical, physical, and morphological properties. The high-temperature burning process imparts pozzolanic properties to the ash, enhancing the compressive and tensile strengths of concrete when used as a partial cement replacement. Various SSA replacement levels (5%, 10%, 15%, 20%, and 25%) are tested, with 15% SSA achieving the highest strength improvements. While SSA influences setting time and workability, treated sewage water shows no significant impact on concrete properties. Concrete incorporating SSA demonstrates superior strength compared to conventional mixes prepared with both fresh and treated water. Durability tests indicate that SSA concrete resists acid attacks better than conventional concrete and exhibits minor efflorescence in saltwater, highlighting its enhanced durability.
