The further application of this material was severely limited by its expensive price and poor fire retardance and  anti-static performance.
The co-solidified behavior of water glass and polyurethane was investigated in this paper based on the modification of  polyurethane grouting material by using cheap  water glass.
The effects of the contents of DOB and catalyst on curing time of grouting material and heat storage temperature  and the prepolymer variety and content  on viscosity and mechanical properties were studied in tihs paper.Then, the SEM was used to analyze the effect of  shearing rate on two-component of grouting material, and  a primary exploration of curing mechanism was made  
at last.
