The aim of this study was the preliminary assessment the effectiveness of application of sodium carboxymethyl starch (CMS-Na) as an additives to green sands with bentonite. Two modified starches CMS-Na having a low and a high degree of substitution (DS), 0.2 and 0.9 respectively, were chosen for preparing moulding sands. Influence of modified starch with different DS on the properties of the green sand was determined based on the results of the determination: apparent density, permeability, free flowability, friability and compressive strength, tensile and shear green sands with the addition of starch. The properties of the starch without starch-based additives were compared with the properties of green sand containing in the composition of CMS-Na with different degree of substitution.
