3. Mechanical properties of UHPC

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.

7. Freeze-thaw test (300 cycles) 100% don't change

• Ice salt denudation < 0.0131b/M2, capillary porosity < 1%

• HRT cycles 100%

• Abrasion resistance (relative volume loss index)1.7

• Oxygen permeation < 10—9M2, total porosity3-6%

• Carbonization depth < 0.02in

8. Way to install: both open installation and concealed installation are acceptable.
