Limestone Addition in Cement - Infoscience

Addition of fine limestone provides an excellent means to reduce the amount of clinker in cement. It is now well accepted that limestone partially reacts in cementitious systems with C3A to produce hemi- and monocarboaluminate phases and as a consequence more sulfate is available to form ettringite and the total volume of hydrates increases.
