At WRF GENT (BE), tests on the fire-resistance sulphur concrete have been conducted.  Thio Material can be classified under fire class A2. From this test, it can be concluded that the behaviour of this material does not contribute to a fire. It is practically fireproof, but it melts at the surface. The behind lying aggregates do not allow the hot pressure points to penetrate deeper. Underneath you can see the impact of 1 kg heavy metal objects heated to respectively 280°C, 405°C and 625°C, that were placed on an element made of sulphur concrete.
