Carbonation of recycled concrete fines as a treatment for promoting their recycling as supplementary cementitious material: influence of initial moisture on CO2 uptake and reactivity.
Construction and demolition waste (CDW) is a major global waste stream. Coarse aggregates from CDW are widely reused, but recycled concrete fines (RCf, <80 µm) remain underutilised, often ending up in landfills or used in low-value applications. Carbonation is a promising treatment to valorise RCf as a supplementary ce...
