The investigation results of the reclaiming ability of a spent moulding sand with the geopolymer Geopol developed by the SAND TEAM Company as well as a moulding sand with a modified binding system based on the geopolymer binder and new hardener offered by the KRATOS Company, are presented in the paper. The basic aim of investigations was the comparison of the reclaiming ability of spent moulding sands with additions of hardeners supplied by various producers. All hardeners were of the same hardening rate. Amounts of the geopolymer binder and of the hardener was the same for both tested moulding sands.
