Abstract

Al₂O₃ is a major constituent of municipal solid waste (MSW) bottom ash that may cause swelling and weakening failure. This paper explores the influence of Al₂O₃ on the long-term mechanical properties of bottom ash. Experimental results indicate that increased Al₂O₃ corresponds to decreases in both the uniaxial compressive and tensile strengths of cemented bottom ash. More specifically, the strength and Young's modulus of cemented bottom ash with high Al₂O₃ content (9.2%) decreased by 22.1% and 40.1%, respectively, after 365 days. Therefore, the long-term mechanical stability of bottom ash with a high Al₂O₃ content is unsuitable for engineering applications.
