| Abstract: | By using sodium silicate as the main agent for the grout,the jel time,viscosity,compressive strength,SEM,water toxicology,IR and NMR analysis of the grout were studied.The results show that the grout can be obtained with adjustable gel time,low viscosity and good mechanical properties.Water toxicology test show the dangerous indicators like heavy metal and organic indicators are all qualified.SEM show that the gel jell well.IR and 29Si NMR analysis confirme that polymer of the silicates is produced. |
