Fire Properties
Enviroc AAC is fire resistance.
Enviroc is non-combustible, no toxic fumes.
Low thermal conductivity of Enviroc reduces the rise in temperature of the embedded steel reinforcement during a fire.
AAC's combination of Low Termal Conductivity, and a Low Coefficient of Thermal Expansion is beneficial during a fire.
Water in crystalline form within the material acts as a heat sink. The internal structure of AAC allows steam to escape without causing surface spalling.
The temperature is lower in AAC than in dense concrete, not only on the non-exposed side but also on the side that is exposed to the fire, perhaps with the exception of the first 5 mm, where it is difficult to measure the temperature. This fact is of importance, as it affects protection of the reinforcing steel in AAC panels.
In many cases the structural parts of AAC were able to continue to serve with minor repairs, after a fire. That reduced the cost of the damage caused by the fire.

AAC can be used as a cladding to protect other materials such as steel structures or to increase the fire rating of concrete walls. |
