Mortars for thermal insulating joints, which contain as aggregates artificial light sands made up of pelleted, pellet slags of granulometry 0-3 mm. Preferably, these slags contain a part of partially ground products containing 10 to 25% of grains of a diameter less than 100 microns. These mortars have an apparent specific gravity between 1,300 and 2,000 kg/m3 and a thermal conductivity of 0.20 to 0.60 W/m DEG C. They are particularly well suited for making joints during erection of walls of light or cellular concrete blocks or multi-alveolar terra cotta walls.
