Title: Mechanical Properties of Ultra High Performance Concrete (UHPC)

Publication: Special Publication

Keywords: steel fibers, super plasticizer, silica fume, reactive powder concrete (RPC), ultra-high performance concrete.
Abstract:Ultra-high performance concrete (UHPC) has evolved in the last couple of decades and it is relatively new type of concrete that exhibits mechanical properties that are far superior to those of conventional concrete and in some cases rival those of steel. The main characteristics that distinguish UHPC from conventional concrete are: the improved compressive strength, improved tensile strength, the addition of steel fibers, high binder content, and high dosage of super-plasticizers, low water-to-binder (w/b) ratio and lack of coarse aggregates. For understanding the possibility of making UHPC with different compositions and mix proportions, more than (224) concrete specimens with different size and shape were cast and tested with concentrating on mechanical properties in different ages and comparing the results also with conventional concrete mixes.
