It is a monofilament copolymer micro fiber added to fresh concrete for the purposes of preventing plastic shrinkage
and plastic seating cracks, reducing their density and reducing their width. It is especially effective in preventing
micro cracks with its diameter of 18 μm and lengths of 6-12-18 mm depending on demand
It can also be used by adding directly to the fresh concrete at the construction site when
In case of adding to fresh concrete, additional mixing time (3 – 5 minutes at high speed, at
least 70 turns) should be applied to ensure homogeneous fiber distribution, and distribution
should be controlled.
An effective mixing should be done for the homogeneous distribution of the fibers without
clumping. Standard procedures should be applied for the protection and curing of fibrous
concretes after they are placed.
It is not the kind of fiber that prevents and bridges wide cracks caused by loading.
It cannot be used as a substitute for structural reinforcement.
Joint reinforcements should be placed and joint cuts should be made.
The workability of concrete containing Oneshot Micro Fiber is lower than non-fiber concrete.
The pulp volume of the concretes where Oneshot Micro Fiber will be used should be
increased, and its fluidity should be improved with superplasticizer additives.
Excessive use of fiber can adversely affect workability
