Abstract:
Concrete is one of the most widely used construction materials worldwide, but the extensive use of cement contributes significantly to environmental pollution and resource consumption. This study investigates the performance of sustainable concrete by incorporating silica fume, rice husk ash, and iron slag as partial replacements for cement. These materials are industrial and agricultural waste products containing significant pozzolanic and silica-rich components, making them suitable for use in sustainable concrete production. The experimental study evaluates the effect of these mineral admixtures on the compressive and flexural strength of hardened concrete. Different replacement levels are considered to assess their influence on the strength and overall performance of concrete. The results are comparatively analyzed to identify suitable combinations of silica fume, rice husk ash, and iron slag for producing sustainable and high-performance concrete. The study demonstrates the potential of these waste-based materials to reduce cement consumption while maintaining the required mechanical properties of concrete.
