Abstract (en)
[origin: WO2008004874A1] Method for coating a matrix with a fire, water and frost-proof barrier as well as the coating thus manufactured. The matrix, which can be a wall in a tunnel, is sprayed-on a first layer of a settable material composition comprising micronized aplite. Then at least one layer of fibre reinforcement is applied on top of the first layer whereafter another layer of sprayable settable material composition is sprayed-on. This third layer comprises aplite, anhydrite, slag and calcite. Both the first and the third layer may also contain conventional hydraulic cements. The applied layers are allowed to set to a hard material.
