Relation between the Rheology Characteristic and Initial Hydration Structure of Portiand Cement董荣珍摘 要:<正>Based on the rheology characteristic... kinds and the chemical admixtures on the initial rheology characteristic and structure forming and developing of cement hydration was studied. The relationship between the rheology characteristic......
network structure for solid particles in the system and the rheology behavior becomes complicated. The apparent viscosity of this dispersing system always has the connection with the volume ratio and the shear rate. In order to discuss the rheology behavior and put up the viscosity model, the suspension of silicon dioxide and silicon oil were prepared. Through testing the viscosity, the solid......

Key words: semisolid alloy; steel; rheology processing; slurry; squeeze casting; solid fraction... morphology. With the modified rheology processing technology, many steel and nonferrous alloy products are first industrially produced using rheological technologies, such as hammers made of high manganese......
the values from different test methods, the slump rheology theory was brought in for verifying and revising the disunity, furthermore, more exact yield stress value was obtained and the operation method..., the values were compared with slump test results from the slump rheology theory. At last, the more exact yield stress value and more rational operation could be obtain. The results show that the value......
increases with the decrease of temperature and wall thickness. Key words: aluminum alloy A356; backward extrusion; semisolid forming; rheology 1 Introduction About 40 years ago, SPENCER et al[1] noticed... by rheological data, such as the degree of thixotropy and pseudo plasticity, the stress–strain curve characteristics and viscosity. In this study, rheology measurements were carried out by back- ward......
