The high performance specified density concrete (HPSDC) is a type of concrete in which a certain proportion of coarse aggregate is replaced with lightweight coarse aggregate. This type of concrete is typically used in offshore structural applications where the wear resistance of concrete is an issue. The main objective of the current study is to provide a quantitative comparison between the properties of the HPSDC compared to the high performance normal weight concrete (HPNWC) and the high performance lightweight aggregate concrete (HPLWAC). The developed mixture incorporated using the optimum coarse to fine coarse aggregate ratio and the optimum maximum aggregate size for this concrete type. Hardened concrete properties were tested according to ASTM standard tests for mechanical properties and abrasion resistance. It was noted that the HPSDC had less but comparable mechanical properties to HPNWC. The HPSDC had less abrasion resistance by an average of 25% compared to the HPNWC. On the other hand, the HPSDC had higher mechanical properties compared to HPLWAC. It had also higher abrasion resistance by an average of 35%.
