The SOSH-1 dry mix, on a mineral binder with reinforcing fibre, is mixed with cold water and applied with plastering machines in several passes, as a rough spray (“shuba”) texture. For steel structures the compound provides up to 150 minutes. On reinforced concrete the result is at least 192 minutes for the first-type limit state and at least 120 minutes for the second. Typical projects are high-rise buildings, transport tunnels and underground car parks.
