Rheological Behavior of Fresh Activated Sludge

, 2014
Despite of few research works on municipal sludge, still there is a lack of actual data. Thus, this work was focused on the conditioning and rheology of fresh activated sludge. The effect of cationic polyelectrolyte has been investigated at different concentrations and pH values in a comparative fashion.

The Rheological Behavior of Wheat Starch Particulates Filled Uncured Styrene-Butadiene Rubber [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2017
This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer ...

Rheological Behaviors of Sumac Concentrate

International Journal of Food Properties, 2008
The individual and interactive effects of temperature (20–50°C), and total soluble solids (TSS) (50–70°Brix), on rheological characteristics of sumac (Rhus coriaria) concentrate were studied using a computer controlled rheometer. Sumac concentrate exhibited Newtonian characteristics for TSS of 50–60°Brix, with a slight deviation corresponding to 70 ...

Rheological Behavior of Volcanogenic Deformations.

Proceedings of the Japan Academy, Series B, 1996
Deformations around volcanoes have been detected by geodetic methods since the beginning of the 20th century, especially in Japan. Generally speaking, the deformations are usually expanding or contracting due to magmatic pressure and are simple compared with the crustal deformations accompanied by earthquakes. Co-eruptive deformations are interpretable

Rheological Behaviors in Polymer Processing

Journal of the Society of Materials Science, Japan, 1964
The rheological behaviors related to polymer processing have been broadly reviewed. The influence of working conditions on the relationship between the flow and the deformation strain has been experimented mainly in respect of compression, for both the amorphous and the crystalline polymers. In particular, the possibility of cold processing is proposed

Study of cement pastes rheological behavior using dynamic shear rheometer

Revista IBRACON de Estruturas e Materiais
Concrete, in its fresh state, has flow characteristics that are crucial to its proper launch and densification. These characteristics are usually measured through empirical testing as the slump test, but this test does not quantify completely the ...
