Mineralizing CO₂ in alkaline construction materials can reduce process emissions. This study measures the effect of carbonic anhydrase on CO₂ uptake and retention in hydrated lime, Portland cement, fly ash, and slag under ambient conditions using a mass-flow-controlled CO₂ supply and gravimetric tracking. CO₂ was supplied for 1440 min for hydrated lime and cement and for 360 min for fly ash and slag, then stopped to quantify permanently retained mass.
