Corrosion and mechanical performance of reinforced mortar and concrete made with MSWI bottom ash
Electrochemical monitoring was performed to evaluate the influence of municipal solid waste incineration residues (MSWI) made concrete, on reinforcement corrosion, using four different steel reinforcements grades, traditional carbon steel B-500-SD and three stainless steels, the austenite AISI 304, duplex AISI 2304, and lean-duplex AISI 2001, embedded in mortars manufactured using bottom ash as aggregates from the incineration of municipal solid waste (MSW), in partial and total substitution of natural aggregate. In addition, it has been studied the mechanical behaviour of the mortar and concrete matrix in the presence of MSWI aggregates. The use of MSWI bottom ash as an aggregate, results in a notable improvement of the resistance characteristics of conventional mortar and concrete, made out only of natural aggregate. Moreover, electrochemical measures show that the steels remain in passive state throughout all the exposure period (3 years). ; The authors are grateful to Projects BIA2011–27182 and BIA2012–32320 of the MINECO, Spain, for financial support. D.M. Bastidas gratefully acknowledges funding from the Ramon & Cajal Program of the Spanish Ministry of Economy, Industry and Competitiveness. ; Peer Reviewed
