Corrosion, MSWI-BA, Ceratonia siliqua, concrete beams, flexure


Civil Engineering


In this paper, the corrosion behavior of reinforced concrete beams containing municipal solid waste incineration bottom ash (MSWI-BA) as a partial sand replacement and Ceratonia siliqua extract as a green corrosion inhibitor was investigated. Four mixes were prepared: (0 and 20% replacement of sand by MSWI-BA with and without Ceratonia siliqua extract). Tests conducted were UPV, compressive strength, split tensile strength, and elastic modulus. RC beams were prepared for determining the flexural performance. Eight beams were casted. Four beams were exposed to accelerated corrosion test and four beams were kept at room temperature. It was found that the compressive strength, tensile strength, and elastic modulus decreased when 20% of fine aggregate was substituted by MSWI-BA and when adding Ceratonia siliqua extract. In addition, the deflection and strain of beams increased. However, the presence of corrosion also affected the deflection and strain and led to increase their values.
