This paper describes the CO₂ capture performance of cement blended paste incorporating gamma-dicalcium silicate (gamma-C₂S) made with industrial by-products, by taking into consideration of effect of CaCO₃, fly ash replacement ratio under the sintering process. X-ray diffraction method was conducted in order to quantitatively investigate the gamma-C₂S content. CO₂ capture performance of mortar sample incorporating gamma-C₂S was investigated by means of compressive strength test using accelerated carbonation chamber. The experimental results revealed that the kind of CaCO₃ would affect the affect the formation of gamma-C₂S after the sintering with respect to the XRD-Rietveld analysis. Moreover, it is confirmed that compressive strength of mortar sample incorporating gamma-C₂S has the same tendency at curing age of 3, 7 and 28days. Blended mortar sample made with 10 wt.% replacement ratio of gamma-C₂S had high compressive strength value compared to normal mortar sample, therefore, incorporating gamma-C₂S had a positive effect on the compressive strength after accelerated carbonation. Finally, the waste foundry sand powder may be alternative to produce gamma-C₂S.
