1. The material has high bearing capacity and good relative toughness. The compressive strength of the material is more than 130Mpa, the flexural strength is more than 16MPa, the flexural compression ratio is close to aluminum alloy, has the high strength of inorganic materials and a certain degree of deformation of metal properties, and the strength ratio is twice that of steel;

2. The material has good fatigue resistance and impact resistance. The material is overlapped by a variety of organic fibers and metal fibers to form a three-dimensional grid structure, which can absorb and disperse the impact energy as a whole, and has good fatigue and impact resistance;

3. The material has good acid, alkali and salt chemical corrosion resistance and good wear resistance. The introduction of ultra-fine powder and silicon powder materials has uniform gradation and very low water binder ratio;

4. The material has a certain self repair ability. Nano powder material is used in the material, and the micro cracks (less than 0.06 mm) formed in the impact process can be repaired by the self reaction of the material in the later stage;

5. The material has good durability. The impermeability of the material reaches above P30, the 28 day carbonization test index is close to 0mm, the migration coefficient of anti chloride ion permeability is 0.4 * 10-12m2 / s, the anti freezing and thawing cycle can reach more than 600 times, there is no mass loss, and the design service life can reach more than 3 times that of ordinary concrete materials;

6. The material has good fire resistance and UV resistance, no combustion, no deformation, and is not affected by UV radiation.
