With respect to normal concrete, UHPCs are endowed with unprecedented compressive strength (150 MPa), tensile ductility (0.1%), and toughness (30 kJ\/m2), which makes UHPC structures impermeable and durable under serviceability limit states. At the material level, UHPC material properties can be further optimized by means of heat curing and the optimal choice of the fiber reinforcement. At the structural level, the design of UHPC structures can be enhanced by means of steel reinforcement, pre-stressing actions, and the combination with steel or other materials in hybrid structures.\u00a0<\/span><\/p>\n<p>\u00a0<\/p>\n<h2><span style=\"font-weight: 400;\">What are the advantages of UHPCs?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">UHPCs effectively enhance construction sustainability by reducing the lifetime costs of a structure and by improving its environmental impact.\u00a0<\/span><\/p>\n<p>\u00a0<\/p>\n<h2><span style=\"font-weight: 400;\">UHPCs applications are expanding<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Bridges<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Footbridges<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Buildings<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Containers<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pre-cast panels<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Concrete foundations in harsh environments<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Marine civil structures<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Marine constructions<\/span><\/li>\n<\/ul>\n<p>\u00a0<\/p>\n<h2><span style=\"font-weight: 400;\">UHPCs are still evolving<\/span><\/h2>\n<p><a href=\"\/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016.png\"><img decoding=\"async\" class=\"alignnone size-full wp-image-9285\" src=\"\/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016.png\" alt=\"Volume of publications (indicative data in 2016)\" width=\"680\" height=\"318\" srcset=\"\/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016.png 680w, \/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016-300x140.png 300w, \/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016-480x224.png 480w, \/wp-content\/uploads\/2021\/04\/Volume-of-publications-indicative-data-in-2016-560x262.png 560w\" sizes=\"(max-width: 680px) 100vw, 680px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">Source : Presans<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Terminology has evolved in the past few decades and is now solidifying under the influence of new norms and national design guidelines.
