Abstract

Abstract

En 中文
• ISA enables cleaner, value-added use as a supplementary cementitious material. • LF-NMR tracks ISA-driven gel-pore refinement and C-S-H densification. • Gel-pore descriptors support strength prediction with errors below 10.60%. • 5% ISA provides the best balance of strength, cost, and carbon efficiency.
