Premco MicroFiber is a high-performance monofilament polypropylene fiber. It is developed to reduce microplastic shrinkage and cracking during concrete hardening, as well as to improve concrete strength and surface quality.
Fibers are also used in concrete mixes to increase flexural and tensile strength and reduce the risk of concrete disintegration.
Premco MicroFiber is a cost-effective and high-quality alternative to steel mesh to control cracking.

Doses

Microfiber Premco is recommended for use in the amount of 0.9kg / m3 of mortar. In this case, there is not only a decrease in the formation of cracks but also an improvement in a number of characteristics of the ready-made concrete. If your only task is to reduce cracking in concrete – it will be enough to use 0.6 kg / m3 of mortar.

Uses

When placing concrete, the standard placement procedures must be followed. Due to the high efficiency of the fibers, slight modifications to the mixture design may be necessary depending on the application.
Premco microfiber is added to the mixer before, during, or after the batching of other concrete components. The mixing time is at least 5 minutes. Premco fibers are compatible with all commonly used concrete additives and performance-enhancing chemicals.

The fiber is not flammable and is not hazardous to human or animal health.
