The character of steel fiber for concrete:
The steel fiber mainly uses in concrete material.The steel fiber concrete is a new type of compound material through rapidly developing since recent twenty years,because the material is added with uniform distributing short steel fiber compound material.It has good crazing-resistance,anti-freezing,anti-bend,
antiwear,washing-resistance etc.It has not only the good character of the normal concrete,but also it makes fragile concrete show good ductility and toughness,as well as nice anti-freezing,antiwear etc.
2,The code of the steel fiber:
item symbol shape specification

curve N 15to37 0.3to1.0
embossing A 15to 37 0.3to 1.0
hook D 15 to37 0.3 to1.0
wave B 15 to37 0.3to 1.0
3,Patterns:CS-N-;CS-B-;CS-A-;CS-D-

4,The use of steel fiber:
It is mainly used in concrete,such as highway,airport,the roof of the house,bridge,mine and so on.
5,How to use steel fiber:
1) For the sake of keeping uniform,first mix 1.5 to2 minutes without water,1 to 2minutes more than ordinary concre� agitating.
2) To press steel fiber down after surface finishing,there aren� discovering steel fiber and mortar on surface.
6,Packing:in 25kg plastic woven bag outside,kraft bag lining plastic film bag inside.
