The rapid development of industrialization and urbanization, the building industry generates a large amount of construction waste, Construction, and demolition waste are usually found whenever any construction or demolition activity takes place such as the construction of bridges, flyovers, roads, etc. Recycling such wastes by incorporating them into building materials is a practical solution to the pollution problem. The use of construction waste as a subgrade backfill material is an auspicious approach to solving the issues of the rapidly increasing amount of construction waste and the shortage of construction materials creates the demand for replacement in concrete materials. The present work has been done to explore the prospect of the full replacement of cement for building block manufacturing with construction waste. Construction waste such as bricks, concrete, and demolition waste exclude scrap wastes (steel, wood, glass, and plastic). Experiments are carried out to assess the compressive strength, water absorption, and durability of the constructed building blocks. The outcomes are compared to traditional building blocks to determine their viability for construction applications. The results show that including crushed brick waste in the sand mixture significantly improved the building block performance, especially under wetting-drying cycles and sulphate attacks. After producing recycled building blocks using construction & demolition waste, field implementation aids in investigating how innovation, sustainability, and prudent resource management can harmoniously converge, paving the way for a robust and environmentally conscious construction industry.
