PHYSICO-CHEMICAL STUDY OF CEMENT DEGRADATION IN THE PRESENCE OF CO2

The Portland cement has several well-known deficiencies when used at a temperature above 110°C and are due to the formation of α-C2SH being a much denser and stiffen forms thereby leading to cement shrinkage and loss of compressive strength. Even worst, in the presence of high concentrated CO2 un...
