ACTIVATION OF METAKAOLIN BY CaO AND CaSO4 ANHYDRITE II
Original language description
The paper presented deals with the activation of metakaolin enabling the preparation of a new hydraulic binder. Activation of metakaolin is carried out using calcium oxide or hydroxide and gypsum or CaSO4 in the form of anhydrite II. CaO and CaSO4 anhydrite II were found to be more effective activators of metakaolin compared to Ca(OH)2 and CaSO4∙2H2O. The binding phase is represented here by an amorphous C-A-S-H phase accompanied with a C-S-H phase indicating similarity with Roman cement. Several crystalline hydrating products are present in the binder with ettringite being the major phase, and CaCO3, Ca(OH)2 and CaSO4∙2H2O constituting its minor phases. In its composition, the binder, which is prepared synthetically, agrees with that of hydrated FBC ashes, and was found to be stable over a period of 2.8 years achieving strengths comparable to those of Portland cement. © 2023 University of Chemistry and Technology, Faculty of Environmental Technology.
