Abstract
The invention relates to a construction panel with high resistance to fire and to a method for producing a construction panel with high resistance to fire.
Claims13
Construction panel with high resistance to fire, comprising:
- xonotlite;
- expanded perlite;
- and,
- fibers, where the expanded perlite amounts to at least 50% by mass, based on the total mass of the expanded perlite, in a grain size of at most 1.5 mm.

Method of producing a construction panel with high resistance to fire, comprising the following steps:
- providing a batch comprising:
- a component comprising calcium oxide;
- a component comprising silicon dioxide;
- expanded perlite;
- fibers;
- and,
- water;
- forming the batch;
- and
- applying pressure and temperature to the formed batch such that the component comprising calcium oxide, the component comprising silicon dioxide, and the water form xonotlite, where batch comprises at least 50% by mass of the expanded perline, based on the total mass of the expanded perlite, in a grain size of at most 1.5 mm.
