The layers you may be seeing can be the ones forming the vaults. The first one in "cerámica a la catalana" used to be taken with gypsum because its shorter time of setting. Some kind of quickly prepared "lost" formwork. Then the others were taken either with lime or mortars for better strength and superior behaviour under water presence. Normally these further layers may be omitted in interior vaults between logs for floors, because the small size of the structure, and simplifications of such system may be found.
