The article discusses the results of an investigation carried out on the chemically bonded and CO2 blown moulding sands using selected, modified inorganic binders. The investigations make an important part of the work conducted within the framework of a statutory activity to optimise the sand technology using new, modified, inorganic binders. The presented results of the investigation of the self-setting sands with new inorganic binders show changes in basic technological parameters in function of time and with varied content of the binding agents. The, very important for a foundry, effect of ambient conditions (temperature and humidity) on the kinetics of the binding process of the self-setting sands with these binders was discussed. In the case of sands hardened with CO2, attention was drawn to the problem of mould and core surface quality, expressed in terms of the friability, very important for the quality of castings made under industrial conditions.
