Modified manganese slag low-carbon cement, and preparation method and application thereof
By designing modifiers loaded with binary polymer copolymers and small molecule organic additives, the activity of manganese slag was stimulated, heavy metals were solidified, and the microstructure of cement was optimized. This solved the problems of low hydration activity and easy leaching of heavy metals in electrolytic manganese slag, while reducing the amount of cement clinker and carbon emissions, thus realizing the preparation of low-carbon cement.

AI Technical Summary
Existing technologies suffer from problems such as low hydration activity of electrolytic manganese slag, easy leaching of heavy metals, negative impact on cement setting and hardening, and high carbon emissions from traditional cement clinker.
A specific binary polymer copolymer is loaded onto the surface of nano-silica as a modifier, and small molecule organic additives are added. By designing the copolymerization of ester monomers and double-terminated polyether monomers, a comb-shaped polymer structure is formed. Combined with nano-silica particles, the activity of manganese slag is activated, heavy metals are solidified, and the microstructure of cement is optimized.
It significantly improves the hydration activity of manganese slag, reduces the risk of heavy metal leaching, reduces the amount of cement clinker used, reduces carbon emissions, and improves the mechanical properties and environmental safety of cement.
