Ultra-High Performance Concrete(UHPC)

Ultra High Performance Concrete(UHPC),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”.

 

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.

About UHPC

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.

Why choose UHPC?

Compared with ordinary concrete, UHPC compressive strength is 3-6 times, flexural strength is 10 times, durability is 100 times that of standard index, and it has excellent tensile performance and super high toughness. Can provide solutions to engineering problems worldwide.

Compared with GRC, in addition to the difference in compressive strength, Young's modulus is more than twice that. The greater the Young's modulus, the less likely to be deformed, the product can be made thinner, and less steel support is required.

In addition to excellent physical properties, UHPC can make almost any shape, from flat to hollow (maximum hollowing rate can reach 70%) to curved surfaces and other special shapes, allowing designers to freely use their creative ideas. And it can express the texture of different materials, allowing the building to reflect different cultural heritage.

 

UHPC has a variety of colors, textures and shapes to choose from, and can provide a variety of design solutions that retain the mineral nature and the color is durable.

The use of high-strength fine aggregates and fiber-reinforced materials can accurately replicate the shape, material, and texture to the maximum extent, and can produce rough or sandblasted surface effects.

GLOSSARY
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.
