Performance Assessment of Enhanced Geopolymer Cement Technology for CO2-Rich Well
The unique characteristics of Portland cement in terms of properties, availability and cost does not allow it to be replaced in many cases. However, there is a certainty about the properties of Portland cement in the long term because of thermodynamical instability of cement in the environment. Thes...
