Production of lightweight aggregate ceramsite from red mud and municipal solid waste incineration bottom ash: Mechanism and optimization. / Sun, Yuehui; Li, Jiang shan; Chen, Zhen et al. In: Construction and Building Materials, Vol. 287, 122993, 14.06.2021.
Field monitoring results reveal that the destruction efficiency of PCDD/Fs are both higher than 99% in two processes. The leaching rate of heavy metals in both ceramsite products, their pollutant emissions in production process meet the standards. Environmental impacts of two ceramsite products were compared using life cycle assessment approach.
The disposal of fly ash has become a serious problem in China due to its rapid increase in volume in recent years. The most common method of fly ash disposal is solidification-stabilization-landfill, and the most common reuse is low-value-added building materials. A novel processing method for preparing ultra-lightweight ceramsite with fly ash was developed. …

The T1 ceramsite was the optimized ceramsite though the extreme vertices design experiment. The T2 ceramsite was selected as a control to analyze the function of the dredging sediment, which had the minimum specific surface area of 14.60 m 2 /g specific surface area and the minimum porosity of 8.12%. The T1 and T2 ceramsite were produced based ...
The ceramsite has the potential to be excellent adsorbent materials or building materials (lightweight aggregates) (Jing et al., 2018; Su et al., 2021). ... The use of sludge alone in ceramsite production can lead to performance degradation and other problems (Tang et al., 2014). To solve this problem, introducing additives can improve the ...
Raw materials (i.e., CG, CFA, and CS) were dried at 105 °C for 1 h and passed through a 200-mesh sieve. Raw materials were directly mixed according to Table 2 with 20 wt% water, rubbed into pellets (5–9 mm), and dried at 105 °C for 2 h. The raw ceramsite would be sintered according to the conditions in a laboratory-type muffle furnace (Model KHXL-1, …
As shown in Fig. 1, the 1 h water absorption of ceramsite with/without red mud was reduced when the sintering temperature rose from 1050 °C to 1200 °C.In addition, ceramsite had lower 1 h water absorption as the sintering temperature was in range of 1125–1200 °C (less than 3.36%), indicating the presence of dense surface layer in ceramsite, therefore obtaining a …
