This article presents the evaluation of three types of grinding intensifier additives which were used for the production of LC3 cement, as well as the addition of LC2 minerals, treated in a laboratory scale ball mill. For its analysis a group of research techniques were applied to study its effect on the rheological and physical – mechanical properties of LC3 cement and LC2 mineral addition. The results of the work indicate that the milling intensifier additives evaluated have a positive impact on the mechanical properties of the samples evaluated, with a slight increase in the water – cement ratio caused by an increase in fineness.
