Abstract
Carbonation behaviour of four cementitious materials, CSA Type 10 cement, CSA Type 30 cement, fly ash and lime, were studied for their applicability to CO2 sequestration. It was found that the cements and fly ash could each show CO2 uptake on the order of 12% while the lime achieved nearly 24%. The two-hour carbonation produced high early age strength in cements and lime, while the strength gain in fly ash was nevertheless not sufficient. XRD analysis determined that the primary carbonation product formed was calcite while C3S, C2S, CSH and CH were the phases consumed.
