文摘

Influence of high volume CFBFA on rheological properties of the cement paste was assessed. Cement paste with different fly ash dosages and types will present different fluid models. Adding CFBFA will reduce rheological properties of the cement paste. Adding ultrafine CFBFA can improve rheological properties of the cement paste. Cement particle size distribution can influence rheological properties of CFBFA cement paste obviously.
