Highway concrete pavement basalt fiber roving

The Chopped Basalt Fiber

The chopped Basalt Fiber is made by the continuous basalt fiber raw silk.
The fiber is coated with Silane wetting agent, it is the first choice material to enhance the thermoplastic resin,
it is also the best material for concrete reinforcement.
Basalt is a kind of high performance volcano rock components,
this special silicate made the the basalt rock has excellent chemical resistance and
alkali resistance. It Is the excellent material to strengthen the concrete and
it can improve the high temperature stability of asphalt concrete,
the low temperature crack resistance and fatigue resistance.
Compared with the organic fiber, basalt fiber elastic modulus,
tensile strength, corrosion resistance and chemical stability, dispersibility and mortar,
concrete affinity has obvious advantages.

Effect
When the Highway concrete pavement basalt fiber roving additive added to the cement matrix..
1.To improve the tensile strength of the matrix.
2.To stop the matrix existing defects (micro cracks) expansion and delay the emergence of new cracks.
3.To improve the deformation capacity of the matrix, and thus improve the toughness and impact resistance etc.
4.It can improve the performance of the concrete effectively.
a.    It can improve the cracking resistance of concrete(mortar) effectively.
b.    It can improve the anti permeability and waterproof performance of the concrete (mortar).
c.    It can enhance the anti impact ability.
d.    It can enhance the frost resistance ability.
