Abstract

As a low-cost grouting material, clay-cement grout has been increasingly applied to grouting construction and other aspects. The current research on its properties is, however, limited to physical mechanical properties such as the compressive strength of its hardened body, permeation coefficient, setting time and stability. As a comparison, there are few studies of the deformability and mobility of grouting materials. To enrich this research area, we used NXS-11A rotational viscometer to gauge the relationship between the change of intermolecular shear force and the change of intermolecular shear rate as our test method. The corresponding results show that the clay-cement grout can be regarded as a type of viscoplastic fluid because its' deformability and mobility curves resemble the viscoplastic fluid counterparts to a large extent.
