Concrete Additive of Polyester Fiber
concrete additive of Polyester Fiber
Fuction:
-Prevent ear1y crack of concrete and effectively resist reflection crack
-Prolong the life span
-Increase the crack-resistance in low temperature
-Increase the fatigue-resistance
-Improve the flexibility, seepage-resistance, and stability in water
-Improve the stability in high temperature
Property:
-Small thickness,
-High Tensile Strength
-Easily scattering,
-Good heat-resistance. It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance
for high-tensile concrete.
