The invention relates to a refractory self-flow filler mortar, comprising in mass % with relation to the basic refractory material, at least 1 % and at most 10 % of non-granulated spherical particles with average size greater than 0.1 mum and less than or equal to 2 mm and further comprising in mass % with relation to the total dry mass of the mortar, less than 4.5% of silica (SiO2) and between 1 % and 8 % water, the standard deviation of the non-granulated spherical particle size being less than 100%.
