Paper Title:
Research on Time-Varying Behavior of Cement Grouts of Different Water-Cement Ratios
  Abstract

The thesis presents an research on the time-varying behavior of cement grouts with different water-cement ratio of 0.5,0.55,0.6,0.65,0.7,0.75,0.8,0.9,1.0,1.1,1.25,1.0,2.0,5.0 and10.0 at 0 minute, 5minutes,10minutes,20minutes,30minutes,60minutes,respectively.This was to investigate the time-varying behavior of reheological parameters of cement grouts with different water-cement ratios.It confirmed that: consistency coefficient and viscosity are time-varying reheological parameters, while rheological index and initial stress(yield stress) are time-independent behavior;the flow pattern properties of cement grouts with different water-cement ratios could remain unchanged with time; the laws with time change of consistency coefficient and viscosity of cement grouts accord exponential function, cp(t)=c0×ekt (Power-law fluid) or hp(t)=h0×ekt(Newtonian fluid or Bingham fluid).These research results have very important realistic value and theory meaning.
