Webb29 jan. 2024 · Viscosity data showed an increase on increasing the glycerol concentration with a trend much steeper than the one reported in Fig 2 for DL data. As a matter of fact, by according data from Ref [ 59 ] to Eq 2 it results b = 8.1±0.5 (R 2 >0.98), and by using the larger set of data from Ref [ 60 ] one get b = 7.2±0.2 (R 2 >0.98). Webb3 juli 2024 · 5.1 Viscosity is a fundamental characteristic for slurries in construction applications. The Marsh Funnel Viscosity test can be used for field quality control of slurries. Relative changes in slurry viscosity can be identified using Marsh Funnel measurements and modifications can be made to mixing and handling procedures.
