Abstract

This research centers on the conversion of blast furnace slag, a major by-product of steel-making, into high-performance

alkali-activated porous thermal insulation materials. Single-factor experiments explored the eff ects of water-cement ratio,

SS modulus, and alkali activator content on BFS-based cementitious materials, and SDS content, H
