“…Compared to the paste sample without benzoate, a shallower depth and a denser layer of corrosion were observed, confirming the beneficial effect of benzoate. In their other work, Kang and Ye [ 14 ] modified alkali-activated slag with copper oxide and copper nitrate. They showed that introducing these materials increased the degree of hydration of the slag, and the material containing CuO showed 100% effectiveness in inhibiting the formation of biofilms and a shallower corrosion depth.…”

The requirements related to reducing the carbon footprint of cement production have directed the attention of researchers to the use of waste materials such as blast-furnace slag or fly ashes, either as a partial replacement for cement clinker or in the form of new alternative binders. This paper presents alkali-activated materials (AAMs) based on blast-furnace slag partially replaced with fly ash, metakaolin, or zeolite, activated with water glass or water glass with a small amount of water, and doped with zinc oxide. The mortars were tested for flow, hydration heat, mechanical strength, microstructure, and antimicrobial activity. The obtained test results indicate the benefits of adding water, affecting the fluidity and generating a less porous microstructure; however, the tested hydration heat, strength, and antibacterial properties are related to more favorable properties in AAMs produced on water glass alone.
