For UHPC concrete, however, the strength has to be increased by reducing water, which will affect workability as a result. In spite of this, UHPC can still be made workable by removing coarse aggregates from the mixture, using ultrafine powders, and adding an31

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 ].
