Cure-to-service design of metastability-confined geo-stable cements
reservoir whose gradual dissolution feeds Na-rich phyllosilicates (e.g., paragonite). The nascent composite gains strength and toughness while maintaining low permeability as metastable species convert to stable phases through staged crystallization. This work defines a design principle of aluminosilicate-based cementitious systems for extreme subsurface applications.
