Application of electric arc furnace slag as an alternative precursor to blast f...
Cristelo, Nuno; Coelho, João Diogo; Rivera, Jhonathan; Garcia-Lodeiro, Inés; Miranda, Tiago F. S.; Fernández-Jiménez, AnaIn steel manufacturing, electric arc furnaces are increasingly common, as they use mostly scrap metal as ore source. Thus, blast furnace slag (BFS) is decreasing, while electric arc slag (EAFS) is proportionally increasing. This study focuses on the potential of EAFS in alkaline cements, as precursor or aggregate. Different EAFS/BFS mixtures, some including fly ash (FA), were activated with a NaOH solution, and...
Compressed earth blocks stabilized with glass waste and fly ash activated with ...
Rivera, Jhonathan; Coelho, João Diogo; Silva, Rui André Martins; Miranda, Tiago F. S.; Castro, Fernando; Cristelo, NunoSustainable alternatives are increasingly demanded as a sound response, from the construction industry, to the worldwide growing concerns with the environment. Such effort is justifiable by the degree of the contribution of this human activity to the problem, and it has thus propelled the development of a major trend in terms of funded research. The study reported in this paper focused on the physical-mechanica...
Stabilisation of a plastic soil with alkali activated cements developed from in...
Cristelo, Nuno; Rivera, Jhonathan; Miranda, Tiago; Fernández-Jiménez, AnaThe development of alternative materials for the construction industry, based on different types of waste, is gaining significant importance in recent years. This is mostly due to the need to increase sustainability of this heavily polluting activity, thus mitigating the dependence on, for instance, Portland cement. The present paper is related to the development of an alkaline activated cement (AAC) exclusivel...
