The scaling laws that arise from dynamic centrifuge modelling contain an inconsistency between the scaling of time for dynamic events and diffusion events. This problem can be resolved by reducing the permeability of the soil, with the help of high viscosity pore fluids. Hydroxypropyl methylcellulose is a water soluble cellulose ether that is widely used to create such fluids. In this paper, the effects that concentration, temperature, ageing, and shearing rate have on the viscosity of hydroxypropyl methylcellulose solutions are examined and equations that quantify them are presented. This information is meant to act as a guideline in preparing high viscosity pore fluids for dynamic centrifuge tests.
