The new DAfStb Guideline on UHPC

On a worldwide scale, ultra-high-performance concrete (UHPC) has been the single most important development of the past few decades in the field of concrete technology and application. This type of concrete is considerably more durable than normal or high-performance concrete. Its high compressive strength of over 150 MPa enables significantly more slender, weight-saving structures that provide the same load-bearing capacity and greater durability in comparison to similar structures made from normal concrete at a roughly identical price level. For instance, UHPC makes it possible to produce...
