一种复合固废基胶凝材料制备方法及其应用
Through the synergistic effect of alkaline activators and sulfate activators, and mineral-modified admixtures, the early strength of composite solid waste-based cementitious materials was improved and the later strength continued to increase. This solved the problem of asynchronous hydration processes, adapted to different construction environments, and improved the fluidity and water retention of the slurry.

AI Technical Summary
Existing technologies cannot effectively activate the silicon-aluminum-oxygen bonds in low-activity solid wastes such as iron tailings and fly ash, resulting in asynchronous hydration processes, low early strength of materials, and slow strength growth in the later stages, which makes it difficult to meet the requirements of modern engineering for rapid hardening and early strength.
By employing the synergistic effect of alkaline and sulfate activators, combined with the nucleation-inducing effect of mineral-modified admixtures, the hydration process of multiple solid waste components is synchronized through grinding and refining of particles and adding modified activators. This results in the formation of hydration products such as ettringite, which serve as nuclei for the hydration products, shortening the hydration induction period, improving early strength, and maintaining later strength growth.
It achieves the synchronization of the hydration process of multiple solid waste components, improves the early strength development rate, and ensures continuous growth of later strength, solving the problem of insufficient early strength or stagnant later strength of traditional solid waste-based materials. At the same time, it adapts to different construction environments, improves the fluidity and water retention of the slurry, and is suitable for pumping construction and thin-layer casting.
