Abstract

Hydraulic properties of belite middling slime obtained as a byproduct in the production of aluminum oxide from nonbauxite materials have been studied. For the purposes of the investigation belite slime and hydraulic lime were mixed in different proportions. Two types of admixtures were used, and their effect on the processes of hydration of the belite slime and strengths of the pastes with equal workability was studied. Development of the processes of hydration and strengths versus time of hydration was studied. By means of the scanning electron microscope, calcium-hydrosilicate phases were identified and a mechanism for their formation was proposed. The results obtained are discussed, and for the investigated binders suitable ranges of application are suggested.
