Original Abstract

Foundries are contaminated by toxic gaseous compounds released during casting into molds. Recently, these moulds and cores containing resins, bentonite, cement or soluble glass as binders of foundry sands are used less often. Consequently, the appreciable attention is paid to ecologically friendly conditions. Therefore, new ecologically friendly binders are developed. As a new binders of 4th generation, different natural biopolymers are being proposed and tested. Bioproteins form bonds with inorganic matrix, even though no chemical reactions take place. The experiments of some tested wastes based on proteins proved to be suitable binders for aluminum casting as well as for their environmental friendliness. Experimental casting have been performed to evaluate the quality and performance of molds with new binder. In addition to, flexural strength and permeability have been measured.
