Effect of Ferrite Phase Content on Hydration Reaction, Mechanical Properties, and Chloride-Binding Behavior of Ordinary Portland Cement

Xue, Jiangwei / Li, Simei / Liu, Songhui / Guan, Xuemao

Ferrite phase ( $C_{4} AF$ ) minerals have a high resistance to chloride erosion, to gain a comprehensive understanding of the effect of $C_{4} AF$ mineral content on the hydration, mechanical properties, and chloride erosion resistance of ordinary portland cement (OPC). In this paper, pure $C_{4} AF$ minerals were prepared by the sintering method and added to the reference cement. The effects of different $C_{4} AF$ mineral admixtures (0%, 5%, 10%, 15%, and 20%) on the hydration, mechanical properties, chloride-binding properties, phase composition, pore structure, and microstructure of OPC were investigated by the isothermal calorimetry, X-ray diffraction (XRD), thermogravimetric differential thermogravimetric (TG/DTG), nitrogen adsorption, and scanning electron microscope (SEM-EDS). The results showed that with increasing $C_{4} AF$ mineral content, the early hydration of the reference cement was delayed, C-10% had the highest compressive strength at 28 and 56 days, and the chemical binding chloride ion ability increased by 86.8%, 46.1%, 105.1%, and 67.8%, respectively (Compared with C-0%). Friedel’s salts could fill the voids and optimize the pore size distribution. This work elucidates the effect of $C_{4} AF$ content on the resistance of OPC to chloride salt erosion.
