Effect of additive on rheology of fine particles slurry suspension

2021 
Abstract Present work deals with the study of rheological aspects related with finer particles of Fly Ash (FA) slurry suspension. The effect of sodium sulfate as an additive has been studied with three different proportions in basic slurry suspension. Throughout the investigation the shear rate varies from 50 to 200 s−1. In this study, additive shows a promising trend in order to improve the rheology of fine particles slurry suspension. The high viscosity reduction associated with the suspension of FA slurry is characterized by high concentration (CW) of additives. However, reduction rate was more dominating in the case of 0.4 (% by weight) of the additives. Results reveals that additive of above manner provides a suitable and alternate arrangement for transportation of fine particles slurry suspension through pipeline at higher concentration.
