Hooked Steel Fiber for Concrete High Strength
RQ®-S2 Hooked steel fibers are cold drawn steel wire fibers with hooked ends. Compared
with ordinary steel fibers, RQ®-S2 Hooked steel fiber reinforced concrete has more ductility and
high load bearing capacity. RQ®-S2 fibers can reduce expansion of micro-cracks due to plastic
shrinkage, drying shrinkage and thermal cracking efficaciously, and intercept the formation and
propagation of macro-cracks.
The main technical performance and characteristics:
High anchoring force. RQ®-S2 Hooked Steel Fibers can generate high anchoring force with cement-based
materials due to the hooked ends, two times more than ordinary steel fiber.
Excellent dispersion. RQ®-S2 Hooked Steel Fiber can get excellent dispersion in the concrete, and convenient
Obviously toughening effect. Adding RQ®-S2 Hooked Steel Fiber into concrete, the fiber improves the
toughness performance of concrete.
Significantly increased impact resistance. The impact resistance of RQ®-S2 Hooked Steel Fiber reinforced
concrete increases a lot compared to the plain concrete.
Reduce shrinkage and creep. Under sustained loading, Homogeneous distribution of steel fiber can reduce
expansion of micro-cracks and macro-cracks.
Usage and notes
Dosage: Common dosage of 39~156kg/m3 (corresponding to the volume dosage of 0.5~2%).
Material requirements: Sea water, sea sand and chloride must not be used in steel fiber reinforced concrete.
Mixing：The fiber, cement, sand, stone added in the mixer, add water and stir; mixing time should be extended to
ensure good fiber dispersion.
Curing: The steel fiber reinforced concrete (or cement) and common concrete (or cement) with the same
construction and curing process.
Safety in use: Appropriate protection should be taken in case of stabbing and splashing into the eyes.
Widely used in the highway pavement, bridge, tunnel, industry floor, airport pavement, building structure,
underground engineering, underwater engineering, water-proof engineering, hydropower station, harbor pavement,
military engineering and all kinds of concrete prefabricated.
Paper package with 20kg/bag(or customized). The packages should be sealed in a cool and dry place. Waterproof
should be ensured during transportation. Shelf life is one year. Handling and transportation is very convenient.
