Polypropylene fiber reinforcing fiber FIBROMAC ®

for concrete

The main objective any passive system to protect concrete against fire must achieve is that, if a fire breaks out, the mechanical characteristics of the structural elements of the concrete remain stable during the process of evacuation and action by the fire brigade (in a tunnel for example), avoiding the loss of human life. Thus, the protection system must act during the first moments of the fire. FIBROMAC® POLYPROPYLENE FIBRES FibroMac® polypropylene fibres are manufactured from extremely fine filaments, produced by an extrusion process. They are designed to protect the integrity of the concrete when it is subjected to high temperatures and direct fire. They also reduce the fissure formation phenomenon caused by retraction or plastic settling and increase control over exudation and segregation phenomena.
