In this study, the possibility of using oyster shell ash (OSA) to partially replace cement in the design of High strength concrete (HSC) was investigated. Six mix ratios were used to investigate strength at replacement level of 7.5, 10, and 15 percent of cement at W/B ratios of 0.22, 0.25, and 0.27; Results showed that there was an increase in strength in all mixes as the days of wet curing increased but decreased as the percentage of Oyster shell ash increased with the least strength of 54MPa at 28 days for 0.27 water- binder ratio with 15% replacement level. The value of 72.2MPa was attained at 7.5% replacement at 0.22 water-binder ratio of mix MA1, while the 0% (control concrete) recorded 74.22MPa at 28 days of wet curing
