Development of ultra-high performance concrete with locally available materials
HighlightsUltra-high performance concrete using locally available materials was developed.Sand gradation, binder content and type, and curing regimens were examined.The concrete strength ranged from 114.1MPa to 155.2MPa.When the binder contains silica fume, using a fine sand does not increase compressive strength.Compressive strength of cube specimens were 11 percent greater than cylindrical specimens cast with the same concrete.
AbstractUltra-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 155MPa was achieved with a silica fume content of 5% and without heat curing. A curing regime of 2days at 60°C followed by 3days at 90°C resulted in the highest strength.
