Polymer rheology analysis
WebApr 7, 2024 · A general linear model statistical analysis was conducted on the relationship between the rheological and chemical parameters to explore the potential differences between various aging protocols. Loose-mix aging in the range of 70–95° was found to be relatively closer to the in situ aging trend using statistical analyses. WebJul 19, 2015 · This method of material analysis was first used by Professor Bingham and Reiner on the 29th of April 1929 when the American Society of Rheology was founded in Columbus, Ohio State, USA. Rheology mostly analyses mechanical properties which include physical properties of liquids and solids by describing the strain and flow behavior.
