UHPC’s superior performance data and index

1、The high compactness and good working performance of UHPC make the surface that contacts with the template have a high degree of smoothness. The outside harmful medium is difficult to intrude into the UHPC, and the colorants and other components in the UHPC are not easily dissolved out. With this characteristic, UHPC can be used as the exterior decoration material of buildings, and the chromatic aberration is reduced to the minimum, which is more conducive to surface cleaning.

2、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、Mechanical properties of UHPC

Creep coefficient	0.3	0.8
Coefficient of thermal expansion	11.8µm/m/°C	11.8µm/m/°C

4、Resistance to acid attack. UHPCis exhibiting high resistance, even under severe conditions (the general concrete will be destroyed), and it’s resistance ability can make it be exposed to various erosion elements (such as calcium sulfate, sodium sulphate, acetic acid, ammonium sulphate, nitrate, sea water and distilled water).

5、UHPC is an Ultra High Performance Concrete (UHPC) which is developed from fine and high strength aggregate. The aggregate size combination has been optimized, so it is the lowest porosity concrete in the market. Because Ductal UHPC uses a specific combination of materials, it is suitable for the production of narrow and tiny components and these components have high durability (abrasive resistance, carbonation, chloride permeability and freezing-thawing resistance, etc.), which are far higher than the traditional concrete materials, such as at least 1000 times lower oxygen permeability. The hollowing out rate can be made to 50~70%.

6、The excellent performance of the material itself and the premixed pouring process make the product quality more stable and controllable, and it is not easy to crack.
