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.

The objective of this study is to investigate the effects of using local waste materials on the properties of fresh and hardened high performance and self-compacting concrete. Crushed ceramic products and steel slag from electric-arc furnaces were used as partial replacements of traditional concrete raw materials in the production of self-compacting and high performance concrete, which were obtained from local factories in Kuwait. Preliminary results have shown that using crushed ceramic products (in the form of powder and 3/8” aggregates) increases the rate of strength gain as the concrete cures, while using electric-arc furnace slag increases the compressive strength of the benchmark concrete mix by up to 40%.
