SikaFiber®-150

(former MasterFiber® 150)

Structural polypropylene fiber for reinforcing sprayed concrete

SikaFiber®-150 is extruded from a natural polypropylene homo polymer and formed into a flat profile with profiled surface in order to anchor it in a cementitious matrix. Due to the large number of fibres per kg, the fibre shape and its anchoring capacity into the concrete, SikaFiber®-150 adds toughness and ductility to the concrete.  

SikaFiber®-150 is user friendly and easy to dose into concrete mixes. It also has high resistance to acid/alkali attack and is therefore suitable for use in wet underground conditions.

Usage

SikaFiber®-150 is recommended for the reinforcement of concrete and wet sprayed concrete applications.

Advantages

SikaFiber®-150 is user friendly and easy to dose into concrete mixes. It also has high resistance to acid/alkali attack and is therefore suitable for use in wet underground conditions.

Packaging

The fibres are packed loose in 6kg transparent plastic bags or in cardboard boxes to suit dosing into the mixer.

Alternative pack sizes are available upon request and should be specified when ordering.

Colour

Polypropylene 100% (translucent, black)

Application

Consumption

Recommended Dosage

The fibers must be added to the concrete mixer after the water and admixtures and mixed for at least 2-3 minutes to ensure even distribution in the concrete.

There may be a slight slump loss after addition of the fibres. Do not add extra water. Adjust the dosage of admixture in the mix to allow the addition of the fibres.


Typically, 6 kg/m3 will produce energy absorption of 700-800 Joules (EFNARC Panel Test) or 280-320 Joules (ASTM 1550) for an in-situ 35 MPa sprayed concrete. However, site trials must be carried out to confirm the performance of the fibre and the sprayed concrete mix.
