Abstract

The objective of this paper was to observe the effect of the addition of the dust from the moulding plant on the quality parameters of the moulding mixtures and determine tolerable content in the moulding mixture. Three types of moulding mixtures were used in experiments: mixture prepared from new quartz sand and bentonite, mixture which is recycled in the experimental foundry and mixture came from the small foundry. To these moulding mixture was added the dust from moulding plant in the range 0 – 10%. Influence of dust addition on the compression strength, splitting strength and permeability was observed in all three kinds of mixtures.

Keywords
