Performance Evaluation of Different Rheometric Shearing Techniques to Disperse Concentrated Cement Suspension

Autor: Mostafa Ahmed M., Yahia Ammar

Publikováno v: Applied Rheology, Vol 25, Iss 3, Pp 23-31 (2015)

Build-up of cement-based suspensions is a complex phenomenon affected by the mixture concentration and testing parameters as well as the shear history. Accurate measurements of build-up rely on the efficiency of the applied pre-shear regime to achiev

We examined the effect of poly-&gamma
glutamic acid flocculant (PGAF) on the removal of ultrafine cement (UFC) particles stabilized by a poly-carboxylate co-polymer, which is a superplasticizer (SP). The flocculation&ndash
