Abstract
Concrete technology is developing fast over the past several decades, and increasingly more high-performance concretes are now available in the market. Among others, ultra-high performance concrete (UHPC) is best known for its high mechanical strength and material durability. In this chapter, historical development of UHPC is briefly reviewed and the effect of each and every of its material components is investigated. UHPC is characterized by its high pozzolanic material content. In addition to the most commonly used reactive material, i.e., the silica fume, effect of nanomaterial addition is presented. In the last part of this chapter, the application of UHPC in protective structures against blast loads is reviewed. The limited test data in the open literature confirmed the blast resistance feature of UHPC.
