Concrete should be mixed  at least 2–3 minutes after the addition of water and admixtures to obtain a homogeneous mix, then add SikaFiber®-150 to the concrete to ensure even distribution of fibres. There might be slight reduction in slump after addition of the fibres, however do not add extra water to the mix. Admixture dosage shall be adjusted to achive and optimun mix.

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 of SikaFiber®-150 per m³ of an in-situ 35 MPa sprayed concrete will provide an energy absorption of 700–800 Joules (as per EFNARC Panel Test) or 280–320 Joules (as per ASTM 1550). However, site trials must be carried out to confirm the performance of the fibre and the sprayed concrete as per the poject requirements.
