High Performance Concrete with the Use of Silica Fumes and Other Materials

Concrete, a composite material, composed of aggregate, generally refers to Portland cement concrete. The downside of plain concrete is that it expands and contracts with change in temperature, shrinks on drying, leads to creeping action, and requires larger sections for carrying load. A new group of concrete that exhibit mainly improved strength & durability properties has recently developed. The Ultra High Performance Concrete (UHPC), also called as Reactive Powder Concrete. It is a high strength, ductile material formulated by combining Portland cement, silica fume, fine sand, Quartz, super plasticizer, steel fibres & water. The aim of this research is to provide a thorough characterization of the UHPC material properties. Various tests like compressive test, split tensile test & durability test have been elaborated in the project for different composition & also comparison between plain concrete and UHPC of different mixes has been discussed with conclusion.
