Using the FT-IR method to study effect of sodium on structure of C3A under different calcination temperatures
QI Junxia, et al
Analytical reagents were used to prepare sodium-doped C3A clinker. The influence mechanism of calcination temperature and Na+ content on the mineral structure was studied. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Rietveld quantitative analysis were employed to investigate the effect of sodium doping at different temperatures on the changes of C3A crystal structure. The results show that the introduction of Na+ significantly reduces the liquid phase formation temperature and affects lattice distortion. When the Na+ doping content is less than 1%, Na+ replaces Ca2+ in the form of solid solution in C3A, causing lattice distortion, while the main phase remains unchanged. The solid solubility limit of Na+ in C3A is 1%. When the doping content of Na+ increases to 3%, the crystal structure changes. When the Na+ doping content exceeds 5%, the main phase of C3A changes and an amorphous product is more easily formed. This study not only verified the applicability of FT-IR in characterizing the structure of C3A in clinker minerals, but also provided theoretical basis and experimental method references for optimizing the performance of cement clinker through ion doping.

Influence of sodium and silicon on setting time of low-calcium fly ash-based geopolymer
WANG Zijie, et al
This paper systematically studied the effects of Si/Al and Na/Al on the setting time of low-calcium fly ash-based geopolymers under different water-binder ratios. Through scanning electron microscopy analysis, the effect of element ratio on the setting time of low calcium fly ash-based geopolymers was explained at the microscopic level. The results show that the initial and final setting times of low calcium fly ash-based geopolymers increase with the increase of the water-binder ratio. Under the conditions of different water-binder ratios, the initial and final setting times of low calcium fly ash-based geopolymers decrease with the increase of Si/Al, but increase with the increase of Na/Al. Compared with Na, Si element has a more significant effect on the setting time of geopolymers during the coagulation process. When the water-binder ratio is 0.45, Si/Al is 2.0 and Na/Al is 2.3, the initial and final setting times of the geopolymer are 49 min and 109 min respectively, and the setting time is better at this time.
