AI Technical Summary
Existing soil and rock solidification materials such as cement have problems such as large drying shrinkage, easy cracking, poor water stability, and insufficient impermeability. Furthermore, industrial by-products such as steel slag and phosphorus slag have low early strength and high expansion when directly applied, making it difficult to meet the engineering durability requirements.
Mineral admixtures are prepared by mixing modified steel slag and phosphorus slag with slag, cement clinker and grinding aids, and then grinding them. The modification treatment improves the compatibility and hydration activity of steel slag and phosphorus slag, reduces the expansion rate, and enhances early strength and water stability.
It significantly improves the early strength and water stability of soil and rock solidification materials, reduces transportation costs, and achieves efficient on-site solidification of tunnel excavated soil, possessing good engineering performance and environmental benefits.
