The UHPC material does not contain coarse aggregate, the particle size of the particles is generally less than 1mm, the UHPC material has ultrahigh strength and excellent durability due to high compactness, and the service life can reach more than 200 years. In addition, because the fine steel fibers dispersed in the UHPC can greatly slow down the expansion of micro cracks in the material, the material has ultrahigh toughness and ductility, is the most advanced cement-based civil engineering material in the world at present, and due to the excellent mechanical property and durability, the UHPC has wide application prospect in the field of bridge tunnels and national defense engineering under the background that the requirement of bridge engineering on light weight, high strength, quick erection and durability is required.

Through experimental research, the following results are found: the UHPC mixture is subjected to hydration reaction from the beginning of entering a mold, the temperature gradually and slowly rises, the hydration heat release quantity is rapidly increased after the UHPC mixture enters the mold after about 10 hours, the hydration heat release rate is gradually reduced until about 20 hours, the hydration heat release is mainly concentrated in 10-20 hours, the entering mold temperature of the UHPC mixture can be obviously reduced by adding crushed ice, so that the temperature peak of a central point is reduced, the time required for melting the crushed ice is prolonged, the mixing time of the UHPC material is prolonged, the production efficiency is reduced, and the consumption of the mixing power is increased. Meanwhile, when the thickness of the UHPC exceeds 20mm, the temperature difference between the center and the outer edge of the cross section reaches 7.3 ℃, the maximum tensile stress value caused by the temperature difference is 4.63MPa, and cracks are easily generated in the internal structure due to stress imbalance. The temperature stress generated by hydration heat during UHPC production is not negligible.
