3M
Introduces Bundled Fibers for Concrete
London - Until
today, the concrete industry had only limited solutions to
the problems of brittleness and cracking. Bringing a new solution
to an old problem, the 3M brand Polyolefin Fibers for Concrete
Reinforcement are effective in increasing concrete ductility,
toughness and crack control.
Because of the way the 3M product is bundled,
there is an increased fiber volume and no balling when properly
mixed at high volumes. This bundle forms a delivery system
that provides a uniform distribution of reinforced fibers
into concrete composites, solving some of the initial problems
of other fiber products.
Advantages of this new product include a reduction
in plastic shrinkage cracks; an increased toughness (ASTM/JSCE);
higher post-crack load-carrying capacity; increased flexural
fatigue strength; increased durability and crack resistance;
greater impact strength, and chemical/sulfate resistance.
The range of fiber volumes possible to give
concrete "designer physical properties" is a feature
specific to the 3M fibers. This bundled fiber system is also
easy to use with standard mixing equipment, helping to solve
concrete problems with equipment that is already in place.
