This research explores the potential of seashell being used in normal concrete. Experimental work has been carried out to determine the compressive strength of concrete by adding the calcined ground seashell ash (GSA). Liquidation technique was used to liquidise the GSA. A total of 4 mixes of GSA were prepared with different variation, which are 1%, 2%, 3% and 4%. All samples were water cured at 3, 7 and 28 days. The findings were yielded in good performance of compressive strength and specimen with 2% of GSA marked the highest strength of 59.77 N/mm 2 compared to other specimen.
