Low-carbon ultra-high-performance concrete: raw materials, particle packing optimization, and data-driven performance assessment—a review

Description

Ahmed Fageeri and Ousmane Hisseine review how to make ultra-high-performance concrete with a smaller carbon footprint, tying together published data on more than two hundred mixtures. This concrete is exceptionally strong and durable, but its recipes lean so heavily on cement that its climate cost is high.

Machine learning models predicted compressive strength from recipe details with high accuracy, though stretch resistance and permeability depended on fine structure the recipe alone cannot capture. Strength measures at different ages tracked each other closely and moved opposite to permeability. One striking pattern: pushing cement content past a certain level added almost nothing to performance while raising emissions steeply. The authors use these links to sketch recipes that keep the strength and durability while cutting the carbon carried by each batch.
