Cure-to-service design of metastability-confined geo-stable cements (opens in new tab)

Traditional cementitious materials, primarily based on Portland cement, destabilize in hot, corrosive geo-fluids, impeding the advancement of geothermal systems as a scalable energy solution. Yet, identifying geo-stable alternatives that meet multifaceted performance demands throughout the inherently non-equilibrium structural evolution over geothermal well lifetimes remains a fundamental challenge. Here, we present a cure-to-service cement design principle that orchestrates the co-evolution ...
