As a new green and environmental material, bio-activated cementitious material is attracting extensive attention. This study confirmed that the bio-activated cementitious material could mineralize and cement fugitive dust into the calcite- consolidation-layer based on CO2 capture and utilization. The results illustrated that treatment processes (non-pressure spraying, pressure spraying, non-pressure blending and pressure blending) had a strong effect on the microstructure and properties of calcite-consolidation-layer. According to the analysis of X-ray diffraction (XRD) and Fourier transform infrared (FTIR), calcite was prepared by bio-activated cementitious material during the cementation process. Meanwhile, scanning electron microscopy (SEM) and thermogravimetric-differential scanning calorimetry (TG-DSC) were adopted to measure the corresponding variation of porous characteristics and calcite content caused by different treatment processes. The results indicated that the microstructure of calcite-consolidation-layer from the spraying process had lower porosity and higher content of calcite than from blending processes. In addition, the mechanical properties of calcite-consolidation-layer were also tested. The hardness and compressive strength, which reached 19.5 GPa and 0.6 MPa, respectively, of calcite-consolidation-layer from the pressure spraying process were higher than those from the other three treatment processes. Compared with the non-treatment process, the four treatment processes had superior wind erosion resistance. Under the wind speed of 12 m/s, the mass loss of calcite-consolidation-layer from the pressure spraying process decreased from 2150.2 to 23.8 g/(m2 h).
