摘要

The unit (1) has a light-weight concrete (2) containing a composition of high-alumina cement of 170-230 kilogram per cubic meters, a portland cement of 0-50 kilogram per cubic meters, perlite of 170-220 kilogram per cubic meters, water of 220-260 kilogram per cubic meters and flux material of 0-10 kilogram per cubic meters. A tongue and groove connection is provided for connecting the unit with the other protection unit, where a fire-proof and thermally insulating single layer plate is used as a tongue material. A thermally expanding coating is applied on surfaces of the tongue and groove.
