Abstract
Dry mix for treating refractory substrates, comprising combustible particles of at least one oxidisable substance which, in the presence of oxygen, gives rise to an exothermic reaction, and particles of at least one other substance, wherein these particles form together, during said exothermic reaction, a coherent mass capable of adhering to and/or interacting with the treated substrate, characterised in that it comprises, as particles of at least one other substance, particles of at least one expanding substance, in that the dry mix without the particles of this at least one expanding substance has a first bulk density and in that the mix comprising said at least one expanding substance has a second bulk density lower than said first bulk density.

Dry mix for treating refractory substrates, comprising
- combustible particles of at least one oxidisable substance which, in the presence of oxygen, gives rise to an exothermic reaction, and
- particles of at least one other substance,
- wherein these particles together form, during said exothermic reaction, a coherent mass capable of adhering to and/or interacting with the treated substrate,
- this mix comprising, as particles of at least one other substance, particles of at least one expanding substance, the dry mix without the particles of this at least one expanding substance having a first bulk density and the dry mix comprising said at least one expanding substance having a second bulk density lower than said first bulk density,
- characterised in that said mix also comprises, as particles of at least one other substance, particles of at least one silica glass, as the majority part by weight of the mix.
