Study on the Effect of Different Water-glue Ratios on the Performance of Construction Cement-based Grout
In order to grasp the influence of different water-cement ratios on the performance of construction cement-based grout,the expan-sion,fluidity and strength of cement-based grout under four water-cement ratios were analyzed.The test results show that with the increase of water-cement ratio,the initial fluidity of cement-based grout gradually increases,and the compressive strength of cement-based grout shows a decreasing law.The overall expansion rate showed a trend of increasing with the increase of water-cement ratio.When the water-cement ratio of grouting material is 0.24～0.30,the electric flux is within1 000 C,which indicates that its chloride ion permeability is low,and the chlo-ride ion diffusion coefficient and electric flux of grouting material increase with the increase of water-cement ratio,and the chloride ion permea-bility resistance gradually decreases.
