ALUMINOTHERMIC DOSE FOR RUN-IN OF REINFORCEMENT'S SLEEVE JOINT

摘要

The solution concerns aluminothermic content for grouting of socket joint of concrete armature. The principle of the solution consists in the fact that it consists of 15 to 25 percent by weight of atomized aluminium powder, of 50 to 60 percent by weight of iron trioxide in the form of round pellets or annealed scales in lamellas containing at most 8 percent by weight of iron oxide, of 20 to 30 percent by weight of metal scrap containing low carbon steel, of 1 to 4 percent by weight of carbonic ferromanganese, of 0.5 to 1.5 percent by weight of ferrotitanium, of 0.5 to 1.5 percent by weight of ferromolybdenum, and of 0.5 to 1.5 percent by weight of calcium.
