Abstract: For the purpose of researching the influence of seawater environment on the viscosity of cement sodium silicate(C-S)grout, the study tested the time-varying characteristics of grout viscosity under different water-cement(W-C)ratio, C-S volume ratio and grouting conditions(fresh water and seawater)by laboratory test method. The results showed that the viscosity of C-S grout could be divided into initial stage and rising stage under fresh water environment. In seawater environment, grout viscosity could be divided into three stages: initial stage, stable stage and rising stage. W-C ratio and C-S ratio directly affected the duration and viscosity of grout in each stage. Due to the complex ionic composition of seawater environment, the viscosity of grout rose to a certain level in a short period of time before entering a stable period of viscosity. Based on the test results, some suggestions were put forward for the construction of grouting in the unfavorable geological body of submarine tunnel, and the research conclusions had certain promoting significance for the safety construction of submarine tunnel.
