The characteristic of STABILS steel fiber

The flexural tensile strength, i.e. the behavior of the material after deviation from the load-deformation curve and initial crack, is to be influenced and optimized. Steel fibers that have an excellent bond to the mortar matrix are of crucial importance for the stability and durability of structural components. The excellent anchorage of STABILS steel fibers perform effectively in optimizing concrete components.

It is important that the fibers reduce the notch stresses at the crack root even in tiny microcracks and distribute them according to the embedment length. An effective way to extend the service life of structural members is to stabilize cracks to prevent the formation of macrocracks.

STABILS steel fibers have high inherent stiffness and reinforce resistance to pull-out.
High-strength straight steel fibers with an efficient fiber geometry strengthen the structure of the components.

STABILS with unique design
Optimum distribution of STABILS steel fiber

An even distribution of fibers and a high number of fibers are of great importance here. It is therefore necessary to reduce the risk of macrocrack formation by an optimum fiber distribution.

In order to improve the material behavior in state II, when the concrete is completely cracked, it is necessary for steel fibers to have a crack-bridging effect by being able to transfer forces over the crack edges. In particular, long and thin steel fibers with a high-performance anchorage are suitable for this purpose.
