Construction pozzolans of Imerys are volcanic tuffs and glasses with amorphous phase above 85%. Imerys’ products are characterized by superior consistency in terms of chemical composition, which allows the customer to produce consistent cement by using a standard formula. Low moisture and relatively fine granulometry ensures the smooth addition of pozzolana to the ball mills.
Cement produced with Imerys’ pozzolana is characterized by good workability and relatively small water demand.
Imerys Construction Pozzolan are associated with very low CO2 emission levels and thus substituting clinker with pozzolan, there is significant reduction in CO2 level of the produced cement.
