Abstract
The paper presents the resultsof an investigationof thegases emission of moulding sands with an inorganic (geopolymer) binder with a relaxation additive, whose main task is to reduce the final (residual) strength and improves knocking-out properties of moulding sand. The moulding sand without a relaxation additive was the reference point. The research was carried out using in accordance with the procedure developed at the Faculty of Foundry Engineering of AGH-University of Science and Technology, on the patented stand for determining gas emissions. Quantification of BTEX compounds was performedinvolvinggas chromatography method (GC).The study showed that the introduction of relaxation additive has no negative impact on gas emissions -both in terms of the total amount of gases generated, as well as emissions of BTEX compounds.Among the BTEX compounds, only benzene is emitted from the tested moulding sands.Its emission is associated with the introduction a small amount of an organic hardener from the group of esters.
