Fluxing properties of sewage sludge ash in brick manufacturing: Effect of phosphorus extraction and brick clay composition

Frederikke B. Feldthus, Lisbeth Mølgaard Ottosen, Ida Maria Gieysztor Bertelsen, Gunvor Marie Kirkelund

Sewage sludge ash (SSA) from wastewater treatment plants has previously shown potential as a secondary resource in fired clay brick production. Previous work has hypothesised but not investigated that P, Fe, and Ca in SSA can act as fluxing agents, thereby improving …

Sustainable valorization of MSWI residues: Mechanochemical immobilization of heavy metals and use as supplementary cementitious materials

Tuan Van Truong, Gunvor Marie Kirkelund, Priyadharshini Perumal

Potentially toxic elements (heavy metals and chlorinated organic compounds) and metallic aluminum (Al 0 ) in municipal solid waste incineration (MSWI) residues pose a critical barrier to their utilization as cementitious materials. In this study, the mechanochemical treatment of all types of …

Dissolution behavior and mineralogical changes of mine tailings subjected to NaOH solution

Anne Mette Tholstrup Tholstru Bagger, Gunvor Marie Kirkelund, Stefanie Lode, Pernille Erland Jensen et autres

Due to the low reactivity of mine tailings in cementitious systems, increasing the pH with alkaline solutions, a process known as alkaline activation, was investigated to enhance their reactivity. This study, therefore, screened the dissolution behavior and mineralogical alteration of nine distinct …
