Rheological constants measurement of mortar that fluidity is evaluated by slump and analysis of slump and slump flow of mortar by MPS method

Abstract

In this study, two rheology tests were conducted to obtain the rheological constants of mortar. The first was sphere pull-up test, the second was the measurement by using rotational vane viscometer. The rheological constants were obtained by approximating flow curve of each test by Bingham model. Using them, the mini slump test was analytically reproduced by Moving Particle Semi-implicit (MPS) method. The analysis results using the rheological constants of sphere pull-up test agreed with the flow spread and slump shape. Therefore, the rheological constants obtained by the experiment are effective for the MPS analysis.
