Is the microporous structure able to protect lightweight alumina aggregates against corrosion of various molten slags? The effects of the slag compositions and structural parameters of alumina aggregates on their slag resistance behavior were investigated, and a dissolution rate model was proposed to describe the dissolution of alumina in the various molten slags inside the pores. Compared to the apparent porosity, the pore size has a crucial impact on dissolution of the lightweight alumina aggregates in the molten slags. A balance between the alumina dissolution rate and the solid phase precipitation rate should be achieved to form an isolation layer. (C) 2017 Elsevier Ltd. All rights reserved.
