For high durability and strength, decreasing of the water to binder ratio of cement is needed by using of fly ash, blast furnace slag as mineral admixture. And it is poin [...]

This contribution aims at a determination of dependence of shear viscosity of polyvinylbuthyral (PVB) on the intensity of electric field to which PVB solutions are expose [...]

The Leonov model, where the Eyring flow model is used to represent the plastic shear rate of the deformation of a material, appears to be a proper choice for the descript [...]

Abstrakt: After mixing kaolin with water attractive and repulsive forces between kaolin particles initiate process of coagulation and peptisation, respectively. The coagu [...]

For rheological description of branched LDPE melts (Escorene LD165BW1 a Bralen RB0323) the following differential constitutive equations were used: eXtended Pom-Pom, Phan [...]

The present contribution indicates that precisely the same situation as with the determination of the so-called yield stress of viscoplastic materials concerns also the v [...]

The article describes results of durability test of a magnetorheological fluid (MRF) which was carried out in a custom design rheometer. The rheometer design allows measu [...]

Abstrakt: The aim of this contribution is to propose a new phenomenological model enabling description of non-monotonicity of shear-viscosity function for rheologically c [...]

Almost all empirical models dealing with the flow curves of nonNewtonian fluids can be applied only in the case of monotonous course of these curves. Exceptionally it is [...]

The aim of this contribution is to present an empirical model taking into account ageing of highly concentrated emulsions. This model enables smooth passage from modellin [...]
