Research on the mix proportion and flow properties of multiple composite C-S based grouting materials

This article compares the performance of different double-fluid grouting material systems through experiments. It was found that the cement system with steel slag fly ash silica fume zeolite powder-water glass has better fluidity compared to other double-fluid grouting material systems, with an initial fluidity value of 37.75 cm and a 30-minute retention value of 39.95 cm. Based on this, the influence of water glass concentration and water-cement ratio on the fluidity performance of double-fluid grouting materials was investigated. The experimental results show that when the waterglass concentration is 13.5%, the fluidity gradually increases with the increase of the water-cement ratio, with a 60.8% increase in the initial fluidity value and a 10.5% increase in the 30-minute retention value.
