AI Technical Summary
In existing technologies, the dilution of activators, particle adsorption, and interference with reaction pathways in alkali-activated materials in water-based drilling mud with high water content lead to insufficient dissolution of precursors, making it impossible to form a robust gel network. This results in low strength and poor stability of the solidified body.
By employing a pre-reaction strategy, a modified CASH gel is first formed in an interfering water-based drilling mud environment through the synergistic effect of modified activators, metal ion modifiers, and auxiliary modifiers. Subsequently, it is mixed with water-based drilling mud to achieve spatiotemporal decoupling of the reaction process.
It significantly improves the efficiency of alkali-activated reactions, enhances the microstructure and durability of the solidified body, enables the efficient and synergistic utilization of multi-source industrial solid waste, and reduces material costs and environmental impact.
