FAQ

• 1. Is the related raw materials authorization certificate, quality certificate and inspection report are perfect for project bidding?

  It's perfect and can be provided in accordance with needs.

• 2. What’s UHPC Ultra High Performance Concrete? What’s the difference between UHPC and other traditional decorative concrete materials?

  UHPC is a ultra-high strength cement-based material with high strength, high toughness and low porosity. Its basic preparation principle is that by increasing the fineness and activity of the component, without the use of coarse aggregate, the defects (pores and micro cracks) within the material are reduced to the least, so as to obtain ultra high strength and high durability.

• 3. What’s the main applications of ?

  UHPC is the main choice of many creative architects and harsh projects. No doubt, it belongs to the ultra high performance concrete series. Each model provides excellent performance: high strength, good ductility, good durability, and excellent architectural aesthetics and sustainability.

  
  

  Born for architecture. Combined with UHPC, this series of unique properties can make people get rid of the limitations of traditional concrete, use less materials, take up less space, design and build more astonishing architectural structures.

  
  

  UHPC is the best engineering material with good durability. The mechanical properties of UHPC with proper reinforcement are close to the steel structure, and UHPC has excellent wear resistance and blast resistance properties. Therefore, UHPC is particularly suitable for long-span bridges, anti explosive structures (military engineering, bank vaults, etc.) and thin-walled structures, as well as in high abrasion and high corrosion environments. At present, UHPC has been widely used abroad, such as long span pedestrian bridge, road and railway bridge, thin-walled silo, nuclear waste tank, steel cable anchorage reinforcement plate, ATM protective containment and so on.

• 5. What are the main competitors of GRC/UHPC in China? What are the superior technical advantages over competing products?

  Competitors are mainly natural stone (marble, granite) and some ceramic and argil brand.

  UHPC high performance concrete can achieve the effect that other materials can not achieve because of its unique high strength and high durability.

  
  

  ①Ultra thin plate 

  ②High durability: service life is up to 200 years 

  ③High compactness: the water absorption of UHPC products is low to 2% 

  ④High stability: The product formula process is very strict, and the texture and color are stable. The color difference of the product is small, and the texture effect change shows low risk. The texture is delicate. It can keep the original performance of the cement products and make the product's surface texture stable to the maximum degree. 

  ⑤High quality: UHPC products are mechanical pouring molding, which ensures product quality stability and high degree of industrialization. 

  ⑥Green low carbon: In the whole life cycle, compared with other decorative cement based products, because of its excellent performance, UHPC has super long service life and needn’t be maintained within 50 years. Life span is higher than other cement based products, and meets the needs of green building materials.

• 6. How much is the price of the product? Does it contain installation construction? Is it retail price or distribution price?

  UHPCraw material-16mm thick, smooth price-about 800~1000yuan/m2 (supply price)

  The main application fields of UHPC ultra high performance concrete are in engineering projects and structure applications, which can realize the requirements of the mechanization and industrialization of the standard plate as well as the customized curved plate and the high hollowed out plate. For specific items and products used, there can be specific quotations (the main price factors: texture, color, modeling, plate width, etc. In addition, specific item information and drawings must be provided then the specific unit price can be provided.)
