Hydraulic Properties of Tetracalcium Aluminoferrite with Adsorption of Silicate Ions
The results obtained in this study confirm that the hydration of C4AF (C: CaO, A: Al2O3, F: F2O3) is retarded by the presence of silicate ions in the solution. In practical terms, C4AF has a low hydraulic reactivity in solution containing silicate ions. The silicate ions in the solution are adsorbed on the surface of the C4AF particles, and they form a silica layer on the surface. From the results of the calculation with the DX-Xα method, it is also believed that silicate ions adsorbed on the surface are very stable, and that there are strong interactions between silicate ions and the surface of C4AF.
