In case of fire, increased water vapor pressure causes dangerous and destructive spalling of concrete fragments and concrete flakes. This process damages the layer above the reinforcement steel. As soon as the critical steel temperature is reached it loses its reinforcing ability to support a structure.
ALP-FIX® MICROFIBERS prevent spalling of concrete creating in course of fire micro channels in the cementitious matrix which enable the harmful water vapor to escape out of concrete without spalling.
ALP-FIX® MICROFIBERS prolong the fire resistance and stability of concrete.
