چکیده انگلیسی
This research presents findings on the influence of high-calcium fly ash (HCFA) on selected properties of fresh and hardened self-compacting concrete and high performance self-compacting concrete. HCFA was used as an additive for concrete (up to 30%) or as a main constituent in cement. Studies have confirmed the possibility of HCFA use in self-compacting concrete, while maintaining the assumed workability of fresh concrete and compressive strength of hardened concrete. HCFA should be processed by grinding, and its amount in the mixture should not be higher than 30% of the cement's mass. Cements that contain HCFA as the main component can be used in both normal and high performance self-compacting concrete. Studies have also confirmed the possibility of the use of high-ash, multi-component cements containing HCFA (CEM X - “CEM V/A (S-W)”) for the new generation of concrete.
