Właściwości reologiczne popiołów lotnych z kotłów fluidalnych

The rheological research has been performed for fly ash originated from the fluidized bed boilers. The suspensions studier included the fly ash alone, or clinker (or cement) with 20% wt. of ash addition. It has been found that pastes from the fly ash alone have large yield value and plastic viscosity. The clinker-asf pastes have lower value of these parameters, comparable with those of the cement-asf pastes. Addition of the superplasticizer leads to much higher fluidity of the cement – ash past when comparing the clinkier-ash one.
