Researches have been geared at not only ameliorating the rising cost of providing affordable housing units to the ever increasing populace but also tackling global challenges such as climate change, environmental degradation, pollution, biodiversity and others concerns and animal bones which have posed challenges through its disposing, treating and processing is the focus of this research by investigating the possibility of its use as coarse aggregate in concrete. Animal bones were crushed in sizes ranging from 10-20mm, these crushed cow bone (CCB) aggregate, were used in concrete specimens as a partial replacement for conventional aggregates in percentages 0%, 5%, 10%, 20%, 25%, and 30%. The particle size distribution of fine aggregates, granite, and cow bone aggregate will be determined in line with BS EN 933-2:2020. Slump test was executed in line with the provisions of BS EN 12350 Part 2: (BSI, 2019). The compressive strength test was carried out using concrete cube (150 mm) specimens in line with the provisions of British Standard codes for concrete (BS EN 12390-3 (BSI, 2019) and cured by immersion for 7, 14, and 28 days. The results of the compressive strength of the concrete made with different percentages of CCB showed very promising strengths between 5- 15% but with optimal strength values at 15% replacement. This implies that CCB can be used to ease the cost of construction in the use of coarse aggregates provided its use is limited to 15% replacements.
