S2 End-hooked Steel Fiber (Dispersed, Glued)

RQS ® -S2 is cold-drawn steel-wire fiber that has hooked ends. In comparison to ordinary steel fiber, RQS ® -S2-reinforced concrete possesses more ductixlity and has a high load-bearing capacity. RQS ® -S2 can reduce micro-crack expansion due to plastic shrinkage, drying shrinkage and thermal cracking, and obstruct macro-crack formation and propagation.

S1 Indented Steel Fiber

RQS ® -S1 Indented Steel Fiber is comprised of cold rolled steel strip created through striping and cutting. RQS ® -S1 can effectively decrease micro-crack propagation as a result of plastic shrinkage, drying shrinkage and concrete thermal stress, and delay macro-crack formation and propagation. RQS ® -S1 significantly improves the crack resistance, tensile resistance, abrasion resistance and fatigue resistance of concrete.

VI Polyacrylonitrile Fiber

RQS ® - VI is comprised of short, thin fibers, predominantly comprised of Polyacrylonitrile (PAN), with a non-circular section shape made by wet spinning for fiber-reinforced high -performance concrete and mortar. The fiber possesses excellent dispersion in cement-based materials with an effective bonding property between fiber and the matrix due to the surface treatment of hydrophilic modification. RQS ® -VI can decrease and impede the plastic and drying shrinkage of cement-based materials. It can also significantly improve the crack-resistance, impermeability, impact and fire resistance of cement-based materials.


Spray Concrete (Setting Accelerator)

SBT ® -N(II) is a high performance alkali-free

SBT ® -N(II) is a high performance alkali-free setting accelerator for sprayed concrete. It speeds thechemical reaction between cement and water which causes mortar to set faster and increase the early strength development. SBT ® -N(II) has the properties of well adapted to cement, quick setting, high early strength and low rebound of concrete. It is widely used in many fields such as mining, hydropower, highway, railway tunnel, laneway, cave and so on.
