Rheology, Mechanical Properties and Porosity of Ternary Alkali-Activated Binders Based on Mining Mud Waste with Waste Glass and Metakaolin

Alkali-activated materials have the potential to replace Portland cement in certain applications. To better understand these binders’ properties, it is relevant study their rheological behaviour at early ages, like case of paste. There are already many studies on available literature, using fly ash, metakaolin, and ground granulated blast furnace slag as precursors. However, this discusses behaviour, mechanical porosity ternary alkali-activated binders based mining mud waste, waste glass, metakaolin. The precursor consisted a volume mix 70% tungsten mud, 15% glass activator was combination sodium hydroxide silicate solution. Five activator/precursor (A/P) ratios (0.37, 0.38, 0.39, 0.40, 0.4) were studied. result showed that ratio affects rheology paste fit Bingham model. relative yield stress (g) plastic viscosity (h) increased inversely with A/P ratio, while workability proportionally. Furthermore, some empirical models proposed describe characteristic stress: spread diameter versus time correlation between parameters diameter. increase has also followed decrease compressive strength all tested samples for ages. As expected, an accompanied ratio.
