Development of ultra-high performance concrete with locally available materials

Ultra-High Performance Concrete (UHPC) is an advanced type of concrete that can enhance the durability and resilience of concrete structures. The use of local materials is a fundamental step to save materials and energy and reduce the cost of concrete. In this study, the effect of sand gradation, binder type and content, and curing regimes on concrete's compressive strength was examined. Results indicated a 90-day strength of 155 MPa was achieved with a silica fume content of 5% and without heat curing. A curing regime of 2 days at 60 °C followed by 3 days at 90 °C resulted in the highest strength.
