The aim of this research is to study the effects of incorporating sea shells into concrete in regards to its compressive strength, workability as well as strain in response to stress. Four batches in total with different percentage of material replacement from 0 to 15% sea shells replacement with a constant 10% fly ash replacement were tested for the stated above tests for concrete cubes curing period of 7, 14 and 28 days. For fresh concrete workability, except for 10S10F the other 2 batches did not reach the designed slump. From the results, batch with 10% sea shells replacement and 10% fly ash has given the highest compressive strength at 36.85MPa due to the optimum replacement of sea shells as fine aggregate that decently fills in the void. Stress-strain analysis also shows that all the batches did not produce a typical concrete behaviour graph. To conclude, it has been proven that fly ash and sea shells introduced to the concrete mixture did not contribute any discernible effect on its workability. In terms of strength, 10S10F yields a higher compressive strength of faring at least 7% higher than the control sample Being a project report submitted to INTI International University as a requirements for Bachelor Of Engineering (Hons) in Civil Engineering January 2019 under the managment and supervision of Faculty of Engineering & Quantity Surveying, INTI International University Dissertations, academic -- Engineering Civil Engineering BCEGI
