Possibilities of partial replacement of cement with sulfocalcic binder based on FBC ash
Original language description
The reduction of CO2 emissions brings new challenges to the construction industry, which are, among other things, related to the preparation of alternative hydraulic binders with a lower carbon footprint. The article deals with the use of a sulfocalcic binder (SFX binder) based on FBC ash as an admixture in concrete. A total of six mixtures containing from 10 to 100 wt.% of SFX binder were prepared. In addition, a reference mixture containing Portland cement was prepared. Selected properties on fresh slurries such as consistency and setting times were studied. The hardened mixtures were subjected to volume stability test and compressive and bending strength tests. Very good properties of binders containing FBC ash compared to Portland cement were found. The initial setting time ranged from 93 to 250 minutes and the final setting time ranged from 168 to 336 minutes. The compressive strength of hardened slurries containing FBC ash ranged from 107 MPa to 127 MPa after 28 days. Although the phase analysis revealed that the main crystalline phase is ettringite, no volume changes were recorded in the hardened bodies.
