Have questions, need quote, call us: (908) 293-8280 Structural macro-fibers have a diameter greater than 0.3 mm. It is therefore imperative that the behavior under thermal stresses for the two materials be similar so that the differential deformations of concrete and the reinforcement are minimized. Continued mixing breaks apart the clips to allow individual fibers to separate quickly throughout the mix. It can be used for underground waterproofing, industrial and civil construction roofing, pool, building transfer beam, mortar plastering and so on.

Added directly to the mixer or ready mix truck, they disperse instantly within the concrete. Using the conventional mixing techniques for normal concrete it is not possible to mix more than about 2% (by volume) of fibers of a length of 25mm. Fibres are usually used in concrete to control plastic shrinkage cracking and drying shrinkage cracking. Learn More. Use of higher percentage of fiber is likely to cause segregation and harshness of concrete and mortar. It boosts surface abrasion resistance and drastically reduces permeability while improving strength properties like no other product on the market today. of the micro polypropylene fibers to 1 yard of concrete. Another important factor which influences the properties and behavior of the composite is the aspect ratio of the fiber. One of the main benefits of fibers are the homogenous distribution in the concrete. Want to keep up with the latest news on our projects, events, and products? Generally fibres do not increase the flexural strength of concrete, so it can not replace moment resisting or structural steel reinforcement.
