Abstract


The paper exposes the results of a study, at macro structural level, on the influence of the calcite grinding process fineness on the red ceramic bricks following properties: Compressive strength, Density, Absorption and Durability, though the performance of physical – mechanical and accelerated aging tests, when this is added in an amount inferior to the 10% in relation with the clay weight. It is proved that when this admixture is ground until fineness between 72 m and 150 m, the above mentioned properties are not affected, however it doesn’t occur this way when it is ground until a particle size of 297m. The carried out study, demonstrates that with this specific surface, the calcite addition affects the red ceramic bricks physical-mechanical properties as well as their durability.
