Specialized Industrial Application

Perlita y Vermiculita has developed different systems for fire protection for the chemical and petrochemical industries. These specialised environments work with highly flammable products and as such, the risks of explosion or fire(s) are exponentially greater.

In addition, studies and historical data from real fires have demonstrated that these fires ignite and spread much faster than in normal situations.It is imperative that the right fire protections are in place.

One of the main measures taken in the chemical and petrochemical industry is the simulation of a fire curve which is more aggressive than that used in construction. Studies and data from real fires have shown that these industrial fires develop much faster than normal characteristics fires.

Currently there are different models that simulate this behaviour. The most prominent are the NPD (Norwegian Petroleum Directorate), developed in Europe, and the curve UL 1709 (Rapid Rise Fire), developed in the United States. Both curves can be used as test curves for the certification of passive protection products in the chemical and petrochemical industry.

Civil Works for Tunnels

Damage from fires in tunnels always has a very high cost, on both the human and financial scale. By its very design nature, tunnels rapidly become ovens in a fire situation, resulting in concrete rubble caused by exploding aggregate blocking access/exits to extinguish/escape.

Pyrocrete 40T Mortar Spray

The human and financial cost of damage from  fires in tunnels can be deleterious.  By its very design nature, tunnels rapidly become ovens reaching extremely high temperatures in a fire situation, resulting in concrete rubble caused by spalling (exploding aggregate) blocking access/exits to extinguish/escape.

When designing a tunnel, it is necessary to take these factors into consideration, to provide for alternative escape routes, proper ventilation, to install fire detection systems, and to develop passive fire protection for the tunnel’s structural elements.  For example, a system to protect the concrete structure is critical, since temperature gradients between the interior of the concrete are greater, given the increased heat that spalling causes.

The cost of repairing a tunnel affected by fire is far lower if a system of passive protection is already in place.

A single powder component mixed with clean, potable water before it is used in application. Recommended use for tunnels.
