UHPC is ultra-high performance concrete, how high can its performance reach? In terms of the main compressive performance of concrete, the compressive strength of ordinary concrete is about 15Mpa-30Mpa (capable of bearing 20-30 tons per square meter), while the high hardness pig iron in our daily life generally has a compressive strength of 200Mpa (capable of bearing 200 tons per square meter). It is said that the highest compressive strength of UHPC can reach 810Mpa (capable of bearing 810 tons per square meter).
The "Three Highs" of UHPC
Ultra high performance concrete is mainly known for its "three highs": high strength, high durability, and high workability.
high strength
As mentioned earlier, the maximum compressive strength of UHPC can reach 810Mpa. Due to significant differences in technology levels among countries, the minimum requirement for UHPC is to have a compressive strength of over 150Mpa and a shear strength of over 25Mpa, as well as high insulation, high waterproofing, and fine texture, which can effectively isolate all harmful media. It can be said to be a towering white jade pillar, setting up a sea of purple and gold beams, independently carrying a piece of sky.
High durability
Traditional concrete inevitably has many gaps within itself. In high or low temperatures, continuous rainy or sunny conditions, the gaps will further enlarge and the service life will be low. However, UHPC itself has almost no gaps, and even if small gaps are caused by external forces, UHPC still has magical self-healing ability.
UHPC was initially used in bridge construction to reduce the weight of the structure, improve its service life and durability. The service life can reach over 100 years.
High work efficiency
Unlike traditional concrete, which has the characteristics of being coarse, bulky, thick, and heavy, UHPC relies on its strong physical properties to make the structure extremely lightweight and has a strong visual aesthetic. Designers can fully implement their imaginative ideas with its excellent performance.
UHPC has a high density, high surface smoothness, and a delicate texture that feels warm and moist like jade. Ordinary concrete is completely rough in front of UHPC. Not only that, the ultra-low porosity also makes UHPC less prone to contamination and easier to clean and maintain.
