Ultra-high performance concrete (UHPC) is a novel con-struction material exhibiting enhanced mechanical and durability properties, which can lead to economical con-struction through reducing the cross-sections of structural members with associated materials savings and lower installation and labor costs (Tang 2004). Henry. the key elements of high performance concrete can be summarized as follows: low water-to-cement ratio, large quantity of silica fume (and/or other fine mineral powders), small aggregates and fine sand, high dosage of super-plasticizers, heat treatment and application of pressure which are necessary for ultra high strength concrete High Performance ConcreteConcrete may be regarded as high performance for several different reasons: high strength, high workability high durability and perhaps also improved visual appearance. And, best of all, it is completely free and easy to use. Abstract: Although intensive research related to ultra high-performance concrete (UHPC) and its composition has been carried out over the past two decades, attaining compressive strengths of over 150 MPa (22 ksi) without special treatment, such as heat curing, pressure, and/or extensive vibration, has been nearly out of reach.
