Description
Milled steel fiber
The milled steel fiber is a high-strength steel wire milling process to produce a high-performance fiber product with anchored ends at both ends and a rough side and a smooth side. It has high tensile strength, good toughness and dispersion, and good adhesion to concrete. The dosage is: 30-80Kg. This product is the main export product. Milling steel fiber is a new and high-performance steel fiber variety. Its length-to-diameter ratio is 34.3; ultimate tensile strength is 808.6mpa; its bonding degree with cement mortar is 3.52mpa
<br>
The rough and clean surface of milled steel fiber can be firmly combined with the cement paste in the concrete. This is the fundamental reason for milling steel fiber to improve the various performances of concrete
Technical Parameters：
Specification model | length(mm) | diameter(mm) | Aspect ratio i/d | tensilestrength(VIPa) | Bending performance |
CW口×口 | 20~60 | 0.3~1.2 | 20~100 | ≥600 | ≥3 |
1.Mouth × Mouth means length × diameter; 2. The number of kg/piece is determined by calculation using nominal length, equivalent diameter, and steel density. The density of steel is 0.00785g/mm; 3. The height of the profile h(mm) 1.5-2.0
Application field：
Highway bridge、Hydraulic dam、Railway sleepers、Port and Ocean Engineering、Tunnel and mine engineering、Pipeline engineering、Other construction projects
Construction suggestion：
For the steel fiber produced by Zhitai, the mixing amount can be 30-80kg/m³ for road construction and 50-100kg/m³ for bridge construction;
Steel fiber concrete mixing process: the construction is carried out as usual, no special adjustment is required.
