The article presents the statistical evaluation of selected properties of moulding sands with additions of various binders. A utilitarian objective of this study was to determine the possibility of using coal dust as an additive to sands to protect castings made in these sands from the burn on defects. Another objective of the study was to investigate the possibilities to eliminate the protective coatings in view of a high cost of their application. The investigations were carried out on mixtures based on silica sand with binders, i.e. P26 flocculant – a complex compound of vegetable origin, and Gigtar – a waste material formed during manufacture of hydrogen cyanid, with an addition of coal dust. Applying the multi-factor analysis of variance, a complex effect of the sand chemical composition, and of the drying time and temperature on dry compression strength R_c^s was analysed.
