This study investigates the use of granite stone dust and Alcofine as partial replacements in engineered cementitious composites (ECC) to enhance mechanical and durability properties while promoting sustainability. Cement production contributes significantly to global CO₂ emissions, necessitating alternative materials to reduce environmental impact. Granite stone dust, a byproduct of stone processing, and Alcofine, a highly reactive supplementary cementitious material, were incorporated in varying proportions.
Concrete mixes were prepared using M25 grade with replacement levels of 15% and 20% Alcofine and 20% and 30% granite stone dust. The specimens were tested for compressive strength, split tensile strength, and flexural strength at curing periods of 7, 14, and 28 days. Experimental results revealed that the combined use of granite dust and Alcofine significantly enhances strength properties due to improved particle packing and matrix densification.
The optimum mix (20% Alcofine and 30% granite dust) showed maximum compressive strength of 183.6 N/mm² at 28 days, outperforming conventional concrete. The study concludes that the use of these materials not only improves performance but also supports eco-friendly construction by reducing cement consumption and utilizing industrial waste.
