The possibility of application of aluminosilicate from the palygorskite (attapulgite) group as a potential substitute for bentonite in green sand system application were evaluated. The effectiveness of the application of this aluminosilicate as a binder in sand grains was determined based on the results of the determination flowability, apparent density, permeability, compacability, wear resistance and compressive, tensile and shear strength of the green sands with attapulgite participation or with a mixture of bentonite-attapulgite. The results with the properties obtained for the green sand bonded by bentonite were compared. Based on these results, it was found that attapulgite as a main binder material in the green sand does not guarantee the respective properties of moulding (e.g. it was observed low green strength properties, high apparent density of mixture, low compaction and very low wear resistance). It was recognized that the natural form of attapulgite require modification in order to obtain the appropriate properties of moulding sands, which is the subject of future work within the scope of the development application of aluminosilicate in foundry industry.
