In this study, we assumed that the cement paste and mortar are continuums proposed a rheological constants estimation equation can be applied to both mortar. After that, effectiveness of equations was verified using MPS analysis, confirmed in low-fluidity However, for high-fluidity mortar, actual measurement results could not reproduced well by analysis. case analysis considering thixotropy.

A study was conducted on healthy subjects to determine whether voluntary ballistic wrist flexion movements are influenced by immediately preceding conditioning of the forearm muscles. Single rapid wrist flexion movements were made in response to an auditory "Go" signal. Rectified surface EMG was recorded from wrist flexors and extensors, and joint position was measured by a goniometer. The move...

[Received on ] Thixotropic yield stress fluids have a yield stress and viscosity which change slowly over time as the fluid undergoes structural changes. This article reviews recent work which shows how such behavior can arise as a limit of viscoelastic flow when a relaxation time becomes large. The large relaxation time introduces a small parameter which can be used as a basis for singular per...
