This could be because the activated bauxite tailings diluted the cement in a cementitious system, reducing the concentration of Ca 2+ in the solution, delayed the Ca(OH) 2 nucleation and generated unstable C–S–H gel with a low Ca/Si ratio (it would tardily transform into a stable C–S–H gel). The end time of the induction stage was ...
