Abstract


The present work primarily investigated the rheological property of two- component EP/PU grouting materials by rotational rheometer. The store-stability of seriflux at different temperatures was studied through the correlation between strain and storage modulus. The relationship between shear stress and viscous modulus demonstrate that the viscosity of grouting materials can keep steady at 10-20ºC. The results showed that seriflux A1 and B1 share similar non-Newtonian index and good groutability at 30ºC.
