High performance concrete (HPC) in three different forms were used in the present research and they were made with mineral admixtures, air entraining agent (AEA) and light weight aggregate (LWA). This paper deals with compressive strength, sorptivity, porosity, corrosion resistance and load carrying capacity of HPC. Experimental results reveal that, HPC with ground granulated blast furnace slag (GGBFS) (20%) and Quartz powder (10%) gave 68.4 MPa (for fck = 70 MPa) the maximum compressive strength among three different forms used. In terms of durability the same mix showed a reduction of 60% in voids compared to control concrete. The load carrying capacity of that mix was only 6% less than control concrete. Performance of HPC made with LWA and AEA was inferior to HPC with mineral admixture. Hence HPC with GGBFS (20%) and Quartz powder (10%) was an optimum mix among the various mixes used.
