In this study, the effects of limestone powder on rheological behavior, pore solution chemistry, mechanical properties and microstructure alkali-activated cements have been investigated. The results exhibit that, with increasing content in ternary system, structural build-up mixture increases earlier. It was observed that flow curves pastes fit Bingham model well. With fly ash mixtures, plastic...

In this study, the stability and rheological properties of a suspension of carbonyl iron microparticles (CIMs) in silicone oil were investigated within a temperature range of 10 to 85 °C. The effect of adding two hydrophobic (stearic and palmitic) acids on the stability and magnetorheological effect of a suspension of CIMs in silicone oil was studied. According to the results, for preparing a s...

The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such s snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstitial fluid (air, water). The bulk ehavior of these materials has often been modeled as plastic materials, i.e., a plastic material yields and st...

Bingham, Schmidt, and Rosenblum (Bingham, G. P., Schmidt, R. C., & Rosenblum, L. D. (1989). Hefting for a maximum distance throw: A smart perceptual mechanism. Journal of Experimental Psychology: Human Perception and Performance, 15, 507-528) found that skilled throwers could heft objects and select the weight in each size that they could throw to a maximum distance. Bingham et al. hypothesized...

The paper aims to obtain the expression of velocity lubricating fluid in hydrodynamic journal bearings by analytical method. In classical short-bearing theory, flow was studied ignoring effect centrifugal force film. However, self-oscillation shaft high-power motors does not follow rules lubrication theory. To explain this phenomenon, a modified form Reynolds equation, which influence lubricant...

The effects of the electrolyte concentration and pH on the settling behaviour, floc sizes and rheological behaviour of kaolinite suspensions were investigated. The results show that the settling behaviour of kaolinite changes with the ionic strength and pH of the suspension. In the acidic pH range, (pH 2) particles settle in flocculated form regardless of electrolyte concentration, however, in ...
