Systems cement-vermiculite (cement ligt) in case of fire does not have the dangerous phenomenon of SPALLING

Spalling occurs when the traditional concrete, is exposed to fire. The phenomenon consists in the explosion of the coating due to the increase of the internal pressure due to the overheating of the water contained that can not evaporate outside. The explosion throws dangerous shards of concrete that damage everything that is located in the surrounding areas and threat en sworkers in installations and fire fighters engaged infire extinguishing. This explosion occurs on several occasions, layer after layer until the total elimination of all the coating. The cracks and gaps, allowing the fire to attack more quickly protected surfaces, drastically riduce the actual duration of fire resistance.
