KORTTA Twist RANGDANEH concrete fiber

 

Technical properties

Specific gravity (gr/cm3) : 0.91

Length (mm) : 30-40-50

Diameter (mm) : 0.3-0.35

Color : white - gray

Melt point (cº) : 160-170

Tensile strength (MPa): 500-600

Module of elasticity (GPa):5.5-6.5

Elongation (%) : 12-15

Acid and alkaline resistance : Excellent

Water absorption : No

 

Description:

Twist macro synthetic fiber is made of modified polypropylene / polyolefin. The fiber is produced in types of monofilament and multifilament. This fiber is distributed uniformly in concrete during  mixing process which improves concrete mechanical and durability properties.

 

Application:

An alternative for shrinkage and temperature reinforcement, decrease in use of reinforcement, and increasing in energy absorption of:

Slabs

Concrete pavement

Bridge deck

Metal deck

Precast product

Shotcerete

 

Benefits:

Reducing plastic shrinkage (effective crack control)

Increasing concrete toughness and fatigue resistance

Increasing life cycle

Elimination of corrosion

Increasing in precast production speed

Cost saving

Increasing energy absorption, flexural toughness and flexural strength
