    The environmental protection issues grow in significance, therefore looking for potential additives of sealing slurries among waste products generated by various branches of industry, e.g. cement industry is fully justifiable. It was generally accepted that the contemporary process of cement production is waste-free as by-products of cement production are utilized at various stages. However, not all by-products are fully technologically utilized. Therefore it seem justifiable to analyze whether or not the cement dust by-product can be used as an additive of sealing slurries for modifying their technological properties so that they can be applied for sealing and reinforcing ground and rock mass purposes. The results of laboratory analyses of influence of various concentrations of cement dust generated by cement plant in Chełm on technological parameters of fresh and set sealing slurries of different parameters of water mixtures based on metallurgical cement CEM III/A 32,5. In the course of the analyses there were established optimum concentrations of cement ash additives in slurries, applicable to such geoengineering works as sealing and reinforcing ground and rock mass, with special emphasis on hole injection methods.
