Cellulose fiber is a high-strength fine denier short fiber,
Extracted from special plants, with natural hydrophilicity,
In concrete, it has a good affinity with cement and other hydrates
It can form a better bond with concrete. Due to the fibre
The dimension is ultra-short and has the characteristics of small monofilament diameter, so in a single
The distribution in the potential volume is larger, which improves the crack resistance of concrete
Performance.
In the process of concrete maintenance, it will be formed by ettringite
Caused by the loss, due to hydration heat and temperature caused by the explosion
Elephant. The inclusion of the fiber can avoid bleeding and segregation
The phenomenon plays the role of retarding coagulation and retaining water, and then improves
The strength of concrete.

How to use:
1, in the case of the original design ratio of the same technology, per cubic meter of concrete mixed 0.9kg.
2. Add fiber and main aggregate together to stir.
3, in the original mixing process time setting, the whole process should not be less than 3 minutes.
Scope of application
Highway, high-speed railway, apron, car yard, bridge deck and other cement concrete projects.
