Technological evolution of concrete : from ancient times to ultra high performance concrete [PDF]

, 2010
Since the fall of the Roman Empire, concrete only suffered significant advances with the discovery of portland cement. The technological knowledge that the Romans held was empirical, based on the principle of trial and error, and allowed the discovery of

Self-desiccation and self-desiccation shrinkage of silica fume-cement pastes [PDF]

, 2017
Self-desiccation is one common phenomenon of high-performance cementitious materials, which are characterized by low water/binder (w/b) ratio and high mineral admixture incorporation. As a consequence, large magnitude of self-desiccation shrinkage, a key

Long term bending behavior of ultra-high performance concrete (UHPC)

Constructii: Journal of Civil Engineering Research, 2014
Unlike normal concrete (NC) the behavior of ultra-high performance concrete (UHPC) is different under long-term efforts, if we refer to creep, shrinkage or long-term deflections. It is well known that UHPC has special properties, like compressive strength higher than 150 MPa and tensile strength higher than 20 MPa - in case of UHPC reinforced with ...
