Effect of chemical–thermal activation on the properties of recycled fine powder cementitious materials

Case Studies in Construction Materials
Recycled fine powder (RFP) collected from construction and demolition waste resources is difficult to use in large quantities due to its low activity. To promote the activity of RFP and maximize its economic and environmental benefits, it is necessary to
