Microfiber for Concrete
Microfiber for Concrete in theory
Microfibers are made up by extremely thin filaments, produced by an extrusion process. Its use is indicated for mortars and concretes for decreasing cracking/fissure mostly caused by shrinkage and settlement, due to its water retention properties. It also improves a better control over exudation and segregation. The microfibers also improve the performance of the hardened concrete, increasing the resistance against abrasion, impacts and fire.
NTC Fibra ® 12 is a polypropylene fiber made up by multifilaments, indicated for concrete and mortar reinforcement, minding the achievement of a uniform composite efficient against shrinkage crackings.
