        abstract = {— The rapid growth of construction activities has led to excessive consumption of natural aggregates and the generation of large volumes of construction and demolition waste. This study focuses on the development of sustainable paver blocks by utilizing recycled aggregates and silica fume as partial replacements in concrete. Recycled aggregates obtained from demolished concrete structures are used to replace natural coarse aggregates, while silica fume, a highly reactive pozzolanic material, is incorporated as a partial replacement for cement to enhance strength and durability.
The experimental program involves the preparation of concrete paver blocks with varying percentages of recycled aggregates and silica fume. Standard tests are conducted to evaluate compressive strength, water absorption, and durability characteristics at different curing periods. The results indicate that the inclusion of silica fume significantly improves the mechanical properties and microstructure of recycled aggregate concrete, compensating for the reduction in strength typically associated with recycled aggregates.
The study demonstrates that an optimum combination of recycled aggregates and silica fume can produce paver blocks with satisfactory strength and performance suitable for pedestrian and light traffic applications. This approach not only reduces environmental impact by minimizing waste and conserving natural resources but also promotes sustainable construction practices. The findings of this research contribute to the development of eco-friendly and cost-effective paving materials for modern infrastructure.},
