AI Technical Summary
Traditional underwater grouting materials are easily dispersed under the impact and dissolution of water flow, resulting in low early strength and unsatisfactory grouting effect, increasing construction difficulty and cost. At the same time, the problem of coal-based solid waste storage has not been effectively utilized.
Anti-dispersion grouting material was prepared using coal gangue, fly ash, silica fume, cellulose, and alkali activator. By optimizing activation technology and compounding process, a high-strength gel and skeleton structure were generated. The alkali activator was used to replace part of the cement, reducing the high-temperature calcination process.
It improves the early strength and anti-dispersion properties of materials, realizes the resource utilization of solid waste, reduces costs and carbon emissions, adapts to the needs of rapid reinforcement, and ensures construction quality and reliability.
