Abstract EN
Ultra-High Performance Concrete (UHPC) is a new generation of concretecharacterized by its high strength, high durability, and high stiffness.
Autogenously shrinkage represents one of the issues of UHPC that occurred atearly ages.
It occurs particularly during the first 48 hours after casting.
Thispaper focuses on the ways that can be depended on to mitigate the autogenouslyshrinkage and obtain the outstanding mechanical properties of UHPC.
Theresults showed that the use of coarse sand and high dose of high range waterreduced the admixture above 5% of cementations of materials weight, and highambient temperature at the time of mixing and casting led to increasing theautogenously shrinkage.
While using fine sand, silica fume at 25% of cementweight, and crushed ice at 50% of mixing water to control the mixingtemperature can reduce autogenously shrinkage is a new generation of concretecharacterized by its high strength, high durability, and high stiffness.
