Retarding mechanism of Zn2+ species in geopolymer material using Raman spectroscopy and DFT calculations
Abstract Geopolymers are the most promising alternative to Ordinary Portland Cement for oil-well cementing and well abandonment. To that end, the slurry needs a required pumping time ensured by the addition of retarders. Although zinc has been widely known to prolong the setting time of geopolymers,...
