It is important to utilize fly ash (FA) as a resource due to its increasing amount. In this paper, a no-sintered fly ash-based zeolitised ceramsite (FACZ) was prepared by a high-temperature steaming method with FA as a main raw material, silica fume (SF) as a reinforcing agent and additional silicon source to achieve the high-value utilization of fly ash. The pore structure, crystal structure, microscopic morphology and functional group characteristics of the samples at each stage were characterized by specific surface area and pore size analyzer (BET), X-ray diffractometer (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FTIR). The effects of alkali concentration, SF mass fraction, temperature and steaming time on FACZ were investigated. The results show that analcime with a good crystallinity can be synthesized in FACZ under the optimized conditions (i.e., 8 mol/L NaOH, 15% SF and steaming at 190 ℃ for 48 h). The specific surface area of FACZ can reach 14.4 m2/g and the strength is 27.25 MPa after steaming. The removal efficiency of FACZ can reach 99.9%, and the maximum removal amount is 31.934 mg/g under the optimal removal conditions. The removal mechanism is a combined action of silanol and zeolite ion exchange, in which the ion exchange is the main cause.
