Abstract Sulfates when present in the formation water would attack and deteriorate cementitious system. In quest to investigate possibility of using geopolymer systems oil-well cementing, durability various corrosive environments has been simulated. Lightweight exhibit different microstructural macroscopic properties compared conventional whose under sulfate widely investigated. It is therefore...

• Calcite precipitation shows porosity reduction with microstructural analysis. Cement paste mechanical parameters are reduced under scCO 2 despite calcite precipitation. Analysis of micro and macro experimental behaviour enables better performance the chemo-mechanical model. The change in average properties cement matrix is predicted using coupled model for attack. Wells drilled carbon storage...
