Steel fiber is a concrete reinforcing material processed to small steel line
with 30¢¦60§® of length and 0.5¢¦1.0§® of wire diameter, which is a
product produced for improving and reinforcing dynamic behavior and
physical features such as tensile strength, flexural strength, and
resistance
against crack by dispersing and mixing with concrete

| Ultra Fiber Chip is a unique brand of steel fiber produced by Daein Co., Ltd. |

* Has high adhesive strength with concrete due to high aspect ratio.
* Because both ends of the product has a hook like shape, ductility and fatigue resistance including softness,
impact resistance, and flexural strength and crack inhibition effect is increased.
*
Because of bundle shape, it can be dispersed evenly in mixing concrete without fiber balling. |

Classification |
Steel Fiber Reinforcing Concrete (SFRC) |
Steel Fiber Reinforcing Shotcrete (SFRS) |
Characteristics |
Indicates Steel Fiber Reinforcing Concrete mixed
with steel fiber having 0.5~1.0§® of diameter
and 30~60§® of length, which is a complex
material having more than 2 times of tensile
strength, 2~3 times of bending strength, and
10 times of impact resistance |
Among the domestic shotcretes, the steel fiber
reinforced shotcrete mixed with shotcrete
having 0.5~0.6§® of diameter and 30~40§®
of length is used for tunneling. Its physical
features are same to those of SFRC |
Uses |
Sports stadium, warehouse, expressway, race
track, shopping center, bridge deck, soil walls,
heavy weight matter per unit area, dealing
company, steel fire resistance equipment,
construction, high strength concrete (chest tube,
PC, water purifier tank), quake proof facility,
nuclear power plant, pressure container, high
security structure construction, military facility,
dam related drainage canal, raceway, blast
resisting structure, marine structure |
Reservoir, dam, repairing, reinforcing, and
lining work, subway/railway/expressway/road
tunneling work, structure restoring and
repairing
work, quake resistant wall,
underground space |
How to use |
Wire diameter 0.6~1.2, length 50~60§®,
water/concrete less than 55%, fine aggregate
minimum size 1/2 of steel fiber, fine aggregate
rate 50~70%, slump 10~12, concrete amount
420~500kg/§©,
Use amount of steel fiber 40kg/§© When using small aggregates (9.5§®) and
increasing water/concrete ratio, strength increate
rate is reduced |
Wire diameter 0.5~0.55, length: 30~35§®
water/concrete less than 50%, fine aggregate
maximum size 13§®, slump 10~12, concrete
amount 420~500kg/§©,
Use amount of steel
fiber 40kg/§©
Length of steel fiber: less than 70% of nozzle
dimension |
