The article presents the progress and applications of ultra-high-performance concrete (UHPC), a revolutionary material in modern construction that offers unparalleled strength, durability, and sustainability. The overview includes the historical development of UHPC, covering its production and design aspects, including composition and design …
Despite the superior properties of UHPC, its application is limited because of the relatively high cost due to the use of relatively large quantities of silica fume [20] and cement. This can be observed in Table 1 for the mix design reported for a commercial UHPC mix (BSI®) [21]..

Rohelise energia tootmine on üks suurimaid keskkonnasõbralikke muutusi, mida oma elus teha. Päikesepaneelide abil vähendad enda ökoloogilist jalajälge, hoiad kokku elektrikuludelt ja saad elektrit tagasi võrku müüa. Et toodetud energiat maksimaalselt ära kasutada, soovitame lisaks paneelidele soetada ka energiasalvesti.

ASTM C672 is often used for the evaluation of scaling resistance of concrete in the United States. UHPC mixtures indicated very low amounts of surface scaling after 50 cycles [71], [125]. The scaling rate of UHPC after 56 cycles was 100 g/m 2, which is 2 [103].
The distinguishing property of UHPC is its tensile capacity. The PCI-UHPC material has high limits and requires at least 2% of high strength, high aspect ratio fibers. It is our goal to …

By exposing UHPC to a temperature ranging from 1000–1200 C, physical and chemical changes occurred in the UHPC matrix, resulting in disintegration mainly due to these alterations. The main reason for disintegration in UHPC structures is exposure to final elevated temperature, blasting, and previous exposure to fire [ 105 ].

Fabrication of UHPC: the UHPC materials were fabricated finally. Similarly, Sun et al. [78] also proposed a mixture design method of UHPC by combining ML techniques and the MAA model. Firstly, they compared predicting accuracy of various ML algorithms (i.e., BP-ANN, GA-ANN and SVM), which revealed that SVM had higher accuracy in predicting UHPC …
