SikaFiber®-200

Bio-based fibers for concrete, screeds and mortars

SikaFiber®-200 is a micronized cellulosic fiber for use in concrete, screeds and mortars to help distribute cracks caused by drying and plastic shrinkage, and thus reduce the risk of early cracking. This natural fiber is an alternative for light crack control reinforcement.

SikaFiber®-200 are extremely fine fibers that disperse very easily in the fresh concrete during mixing and create a very dense fiber network, to help distribute stresses in the curing concrete that cause larger cracks due to drying and plastic shrinkage. Important Note: Fibers can replace traditional wire mesh used to control plastic shrinkage, but shall not be used for structural use.

Usage

For most types of non-structural concrete and cementitious mortars to improve resistance to drying and plastic shrinkage cracking:
  • Slab, floors 
  • Fluid screeds, traditional screeds 
  • Road elements (roadways, sidewalks, car parks, etc...)
  • Aesthetic concretes (coloured concretes, stamped concretes, washed concrete...)
  • Mortars
 

Advantages

SikaFiber®-200 are extremely fine fibers that disperse very easily in the fresh concrete during mixing and create a very dense fiber network, to help distribute stresses in the curing concrete that cause larger cracks due to drying and plastic shrinkage. Important Note: Fibers can replace traditional wire mesh used to control plastic shrinkage, but shall not be used for structural use.

NOTE: Do not pre-soak the fibres in water before adding to the mix.

Application

Consumption

Recommended Dosage

To improve resistance to drying and plastic shrinkage cracking, 300 g of SikaFiber®-200 per m3.
Depending on the desired performance, it is possible to use a higher dosage.
In any case, it is recommended to carry out tests to determine the optimal dosage for the application and the desired result.
