Film coating solutions containing different grades of HPMC (E5, E15 and E50) with and without polyethylene glycol (with various molecular weights) were examined by an oscillatory method, using Haake CV 100 rheometer. Fundamental rheological parameters (?, G? and G² ) were measured over the frequency range from 0.04 to 2 Hz. The variation with frequency of the loss tangent (a ratio of viscous to...

In this study the rheology of blood clot is measured with the help of rotational rheometer. Several shear strain (0.5, 1 and 2%) are applied with two frequencies (5 and 10 Hz) from the incipient time of clot formation and the response of the sample is measured with the form of shear stress and the phase lag which is interpreted with storage and loss moduli. In this study the ratio of loss to st...

Three interlaboratory tests conducted by European laboratories were studied, in which 37 participated 2018, rising to 46 2019 and 2020. A RTFO-aged neat bitumen 20/30 PMB 45/80-55 unaged conditions tested using a DSR at frequency of 1.59 Hz with PP08 PP25 geometries temperatures ranging from 10°C 65°C. To assess variation numerous areas test method EN14770:2012 practices the underlying impact o...

In this work, a methodology to perform rheological studies on smoothed dissipative particle dynamics under arbitrary flow configurations is introduced. To evaluate the accuracy and flexibility of proposed methodology, viscometric for Newtonian fluids pure shear, extension, flows in bulk or near walls are The applicability obtain viscoelastic properties non-Newtonian fluids, such as polymer solu...

Layered double hydroxides (LDHs) can shield polymeric materials from UV light, which allows reducing material aging and erosion damage of bituminous pavement under physical chemical action. In this study, the physicochemical properties, resistance, resistance to aqueous solution LDHs modified bitumen mastic (BM) were characterized by Fourier-transform infrared spectroscopy, basic tests, viscosi...

C3A ratio is one of the parameters that greatly affects rheological properties cementitious systems. With increase in ratio, water reducing admixtures and/or requirement increases to achieve target spread. Some are taken into account such as type rheometer, application method, homogeneous preparation mixture and admixture content determining water/cement (w/c) mixtures produced for measurement ...
