Effect of particle size and CO2 treatment of waste cement

 · This paper studies the role of CO 2 treatment and the impact of particle size (<75 μm and 75–150 μm) of waste cement powder (WCP) with different cement replacement content (0 5 10 15 20 and 30 ) on the physical properties and microstructure of blended cement paste. The results show that carbonation of WCP can effectively increase the flowability of paste due to the formation of
