N2 - High strength concrete has many advantages due to the dense microstructure that led to improved durability and use of smaller concrete cross sections; hence, reduction in total structures’ dead loads. However, developing a high strength concrete with local materials and without special curing techniques can be challenging. In this paper, a high strength concrete matrix with a target compressive strength of 100MPa using locally available material in the United Arab Emirates (UAE) was developed. Ground Granulated Blast-furnace Slag (GGBS) and micro silica were used as a partial replacement of cement. Locally available dune sand and crushed sand (0-5mm) were used as fine aggregates. Ratio of dune sand to crushed sand was the main variable considered during the development while maintaining the same binder to aggregate ratios for all mixes. Furthermore, the samples were cured in a water tank for 28 days at regular room temperature. Initial results indicated that 96 MPa cube compressive strength could be achieved using the locally available materials and commonly used curing methods.
