Performance of Belite Cement Clinker from Completely Recyclable Cement Mortars

Abstract

Abstract: Completely recyclable concrete refers to concrete that can be directly used as raw cement materials for calcination and preparation of clinkers after being demolished. In current studies, the target clinker is ordinary Portland cement clinker. In this study, the completely recyclable mortar (CRM) with high belite cement clinker (HBC) and high ferrite-belite cement clinker (HFBC) as target regenerated clinker was prepared. A comparative study was conducted on the effects of the some rate value and calcination temperature on the burnability of cement raw materials, clinkers’ compositions, and performance using fully CRM and chemical analysis pure reagents (as a control group) as raw materials. The results indicate that the clinker obtained from CRM has a higher rate of later strength growth than the control group. Raw materials with CRM have better burnability and lower CO₂ emissions. However, the strength of clinker is sensitive to temperature, and the range of calcination temperature is narrow. The generation of C₃S in HBC prepared with CRM is significantly inhibited, and the early hydration activity and strength decrease, but the later hydration ability is improved. Due to the presence of impurity ions, here is α′-C₂S mineral phase in clinker. For HFBC group, the hydration activity of experimental group with CRM significantly improves compared to the control group. The research can provide support for the design of completely recyclable concrete.

Key words: completely recyclable cement mortar, belite cement clinker, burnability of raw material, mechanical property, hydration activity
