| Abstract Scope |
Activated alkali materials (AAMs) have been increasingly studied as a substitute for Portland cement, one of the most used materials in civil construction, which during its manufacture, emits a large amount of carbon dioxide. Activated alkali materials originate from one or more precursors, containing mainly alumina and silica, in addition to an activator with a high alkaline content. This work aims to analyze the properties in the fresh state of three pastes of AAMs with different proportions of metakaolin (MK) and flue gas desulfurization residue (FGD). The proportions are 100% MK, 90% MK and 10% FGD, 80% MK and 20% FGD. For each dosage, consistency index tests, incorporated air content and mass density in the fresh state were be carried out. The results show promisingly the potential for using FGD in AAMs folders, meeting the recommendations of the literature. |
