company news about Spraying concrete

In modern construction technology, wet sprayed steel fiber concrete is gradually used, and steel fiber with a length of 20-40mm and the diamater 0.5mm is currently used. The advantages are:

1)  The rebound rate of 5%~10% is much lower than that of dry spray;

2)  The springback of steel fiber is not produced, and the springback can be controlled when using 40mm steel fiber;

3)  The quality of the concrete is uniform, usually up to 55MPA, and for special operations, it can reach 100MPA;

4)  Good environmental conditions and less dust;

5)  Work safety;

6)  Low water-cement ratio and low water permeability;

7)  Anti-corrosion treatment is not required, which can prevent electrolysis and accelerated corrosion
