Fire protection of re-bar
memory®-steel has a similar reaction to fire to that of conventional steel, losing strength significantly from about 400°C, and reducing its prestressing to zero at about 350°C.
If minimum concrete element dimensions and covers comply with the local standard, protection in the event of fire is generally guaranteed.
If the fire protection of the mortar layer is not guaranteed, it can be further improved with SikaCem® Pyrocoat. Learn more (german)
The fire protection measures and stated layer thicknesses are guide values and must also comply with all relevant local regulations and standards.
