Glassman Fibres are designed for use in dry mix systems or other premixing process. The glass strands permits efficient reinforcement at low dosages. It has the flowing properties – Good liquidity and integrity. Glassman glass Fibres are also used at low addition level to prevent cracking & improve the performance in concrete. Glassman glass fibres do not protrude through the surface and require no additional finishing procedures. Adding glass fibres in concrete minimizes early shrinkage cracks during the concrete setting phase. It works best for shrinkage cracks and with Steel Fibre mix for reinforcement and flooring. It is extensively used for spray concrete, plastering in buildings and structural works like beam and columns. There are two types of glass fibres- AR glass fibres which is Alkaline resistant and E-glass fibres which has low alkaline resistance.
ADVANTAGES AND BENEFITS
Chemical Resistance high Modulus of elasticity
- Easy mixing
- No Rusting
- Increased durability
- Crack control
- Suitable for both premix and spray
- It is particularly suited to the preparation of pre-bagged mixes of special mortars or renders.
- Used in Precast products for anti-crack benefits.
DOSAGES
- 6 to 1 Kg per m3 of concrete
- 85 – 150 gms / bag of cement.
- Higher the dosage better will be the mechanical properties.

APPLICATIONS
- Flooring with steel fibres to avoid surface cracks
- Plastering
- Concrete products (Precast pipes, paver blocks and bricks)
- Readymix concrete.
- Dry mix
- Exterior panels
DIRECTIONS TO USE
Glassman fibres can be mixed with RMC plant or truck or into the site mixer as well. While mixing in plaster/ concrete/ wet mix it is added in the end. Long enough till it disperses properly.
