Influence of temperature on rheological properties of self-compacting mortars and concretes in rest state [PDF]

open access: yesArchives of Civil Engineering
The rheological properties of fresh mortars and self-compacting concretes (SCC) at rest – the static yield value gs and the thixotropy factor AT – at temperatures from 10 to 30°C were investigated.

Tough, Stretchable, and Thermoresponsive Smart Hydrogels

open access: yesGels, 2023
Self-healing, thermoresponsive hydrogels with a triple network (TN) were obtained by copolymerizing N-isopropyl acryl amide (NiPAAm) with polyvinyl alkohol (PVA) functionalized with methacrylic acid and N,N′-methylene bis(acryl amide) crosslinker in the ...

Effect of Shear History on Solid–Liquid Transition of Particulate Gel Fuels

open access: yesGels, 2023
Investigating the structural evolution of particulate gels is a very challenging task due to their vulnerability and true flow characteristics. In this work, deeper insight into the rheological properties of gel fuels filled with fumed silica (FS) and ...

Numerical Study of the Effect of Thixotropy on Extrudate Swell [PDF]

open access: yes, 2021
The extrusion of highly filled elastomers is widely used in the automotive industry. In this paper, we numerically study the effect of thixotropy on 2D planar extrudate swell for constant and fluctuating flow rates, as well as the effect of thixotropy on

Effects of high pressure homogenization on rheological properties of rice starch

open access: yesCyTA - Journal of Food, 2019
Gelatinized starch paste was prepared by gelatinizing rice starch at 95 °C in a water bath. Then, the rice starch (both normal rice starch and waxy rice starch) paste was subjected to high-pressure homogenization at homogenizing pressure of 20, 40, 60 ...

Water Clusterization in the Interparticle Space of Hydrophobic Nanosilica АМ-1

open access: yesФізика і хімія твердого тіла, 2021
The processes occurring in hydrated powders and concentrated suspensions of hydrophobic silica were studied by 1H NMR spectroscopy. It is shown that a mixture of methyl silica and water with a hydration of less than 1 g / g is a wet powder, where water ...

Rheological and sensory characteristics of yoghurt-modified mayonnaise

open access: yesCzech Journal of Food Sciences, 2008
Rheological and textural characteristics were studied in a set of 11 samples of yoghurt-modified mayonnaise at 15, 20, and 25°C. The rheometer Rheostress 300 was used to determine the static yield value, apparent viscosity, thixotropy, and elasticity ...

Study on the Thixotropy of Mineral Dispersions

open access: yesYankuang ceshi, 2014
At present, there is no national standard method to regulate the test method of thixotropy. The light industry standard of QB/T 1545-1992 is still available to test the thixotropy of nonmetallic mineral materials. The test method of thixotropy introduced
