Abstract
Although high energy shear mixing is widely accepted as an important factor in microfine cement grouting, little quantitative information is available to assess the effects of variations in the type of mixing and its duration on the rheological properties of microfine cement grout. In this study microfine cement grouts at several different water-to-cement ratios were mixed using four different high energy mixers and a laboratory paddle mixer. Then, tests were conduct to determine the viscosity, sedimentation characteristics, set time, and compressive strength of the neat grouts. It was found that mixing conditions influence the behavior of the grout, quite significantly in some cases, with low water-to-cement ratio grouts exhibiting the greatest change in properties.
