Study on Performance of Grouting Fluid Mixed with Clay-Steel Slag Powder

By designing orthogonal experiments, mixing different amounts of clay, steel slag powder and polycarboxylic acid water-reducing agent into ordinary Portland cement, prepare grouting liquid according to different water-cement ratios, and analyze the grouting liquid under standard curing conditions. Fluidity and water separation. The test results show that: with the increase of the clay content, the fluidity and water separation rate of the slurry gradually increase. As the content of steel slag powder increases, the fluidity first increases and then decreases, but the overall trend is increasing, and the water separation rate increases.
