Data-driven material screening of secondary and natural cementitious precursors

Communications Materials
Cement production contributes to  >6% of global greenhouse gas emissions, driven by clinker’s energy-intensive production and limestone calcination. Replacing clinker with alternative substitutes is an effective decarbonization strategy. However, typical
