Ultra-high-performance concrete (UHPC) generally needs to be mixed with steel fibers or polymer fibers, thus becoming ultra-high-performance fiber reinforced concrete (UHPFRC). UHPC is a material designed based on the close-packed theory. It is the most innovative cement-based engineering material in the past thirty years and has achieved a great leap in the performance of engineering materials. "Ultra-high performance" is characterized by having "ultra-high strength", "high toughness", "low permeability" and "high volume stability".


UHPC is an ultra-high-strength cement-based material with high strength, high toughness, and low porosity. Its configuration principle is by improving the fineness and activity of the component, without using coarse aggregate, the pores and micro-cracks in the material are minimized to obtain ultra-high strength and durability.



Basic Features:

High strength, fire resistance, riot resistance, hail resistance, and chemical corrosion

 • resistance: without the need for additional reinforcement, it can achieve thinner interfaces, longer spans, light weight and elegance, and is more innovative.

 • High durability: It can withstand the penetration of various harmful substances into the matrix and has the ability of self-healing and good waterproof effect.

 • Aesthetics: The shape is arbitrary, can mix a variety of colors, use molds to achieve a variety of textures, with good performance.

 • Ductility: The combination of cement-based materials with metal fibers and organic fibers achieves an organic balance of compressive strength and flexural strength.


Compared with ordinary concrete, UHPC's compressive strength is 3-6 times, and it has excellent tensile properties, reflecting the ultra-high toughness. Compared with GRC, apart from the difference in compressive strength, the Young's modulus is its 2 times more. The larger the Young's modulus, the less likely it is to deform. The product can be made thinner and requires less steel frame support.


Technical indicators:




ASTM- (formally known as the International Association of Testing Materials IATM) is an organization of professionals who create international standards covering materials, construction and testing methods for materials.
ASTM---American Society for Testing and Materials PCI-(precast/prestressed concrete intitute) have developed the recommended practices, procedures and standard for GRC
Composites Fabricators Association- A trade association formed in 1979 to provide education and support for composites fabricators in the successful operation of their businesses. The membership is primarily corporate, but also includes consultants and academics. Although CFA covers the entire composites industry, its focus is on fiberglass (GRP) composites.
