Research on the Performance of Ba-Bearing Aluminoferrite Cement

Abstract:

This paper discussed the main clinker minerals and their optimal proportion of Ba-bearing aluminoferrite cement. The results show that the optimal sintering temperature is 1365°C. In XRD patterns, the diffraction peak of C_2.75B_1.25A₃ and C₄AF nearly disappear when the harden cement slurry hydrated for 3d at absent of gypsum. At the same time, a large numbers of hydration products like BaSO₄ and C_xAH_y which including CAH₁₀, C₂AH₈, C₄AH₁₉ and so on, appear in XRD patterns. So the hydration rate of Ba-bearing aluminoferrite cement is fast and the degree of hydration is high. These hydration products come into being a stable structural frame so that 3d compressive strength of the clinker can reach to 73.3MPa.
