The selection of raw materials of steel fiber
The choice of steel fiber raw materials. Steel fiber varieties are mainly divided into 4 categories:steel fiber, shear fiber, melt extraction fiber, fiber. Milling steel fiber suitable, for the success of the experiment has an important significance or not. Because the steel fiber concrete damage, mostlythe fibers are pulled out and not pull off, therefore, to improve the bond strength between
fiber and matrix is one of the main control factors of improving fiber reinforcing effect. Steel
fiber factory to provide affordable, welcome inquiry.
There are 3 ways of steel fiber:
1 the increase in bond length fibers (i.e., the ratio of length to diameter), but the fiber too
long easy pilling, impact and easy construction and too small, easy bending, length diameter
ratio should bebetween 40-100.
2 to improve the bond performance of steel fiber in the matrix.
3 to improve fiber shape, increasing the friction between the fiber and the matrix and bite
force.According to the above three methods, we compare the list of four kinds of fiber did,
from the table we can see that the milling fiber has better overall performance, it is the 80
time the successful development and current development of a steel fiber quickly, it can
reduce the dosage of steel fiber, prevent the cabbage, easy construction, therefore, we
choose harex milling fiber.
