摘 要：The viscosity evolution for different temperatures was studied experimentally.A time-varying viscosity model was derived and the influence of the initial temperature on gel time was analyzed.The experimental results show that the viscosity of polymer grout increases exponentially with time.It can be divided into two phases.Before gelation,the viscosity variable quantity is very small.At the gel point,there is a sudden increase in viscosity.The initial viscosity and gel time decrease with the increasing initial temperature within a certain range,The study contributes to deepening understanding of the rheological properties of polymer grout,which can provide some references for polymer grouting construction.
