A sustainable solution for ceramic and steel wastes in self-consolidating, high-performance concrete

This study aims to investigate the applicability of using waste materials produced in Kuwait as partial replacements of conventional concrete materials in self-consolidating, high-performance concrete. Processed ceramic products, along with steel slag obtained from electric-arc furnaces, were used as partial replacements of coarse and fine aggregate at various dosages. The fresh and hardened properties of the concrete were then measured and compared. Results have shown that using crushed ceramic products (in the form of sand-like and 3/16” aggregates) increases the rate of strength gain as the concrete cures, while using electric-arc furnace slag to replace 3/8” aggregates increases the compressive strength when compared to a benchmark mix.
