Binder mixture for embedding or molding composition, e.g. for metal casting by lost wax process, refractory cement, mortar, concrete or repair composition, contains ground Portland clinker powder as hydraulic binder

摘要

The invention relates to a dry mixture of embedding material or moulding material for producing embedding or moulding material for a metal casting method, such as the lost-wax method, said mixture containing a hydraulic binding constituent. Said binding constituent contains, as a hydraulic binding agent, ground Portland cement clinker which is free of sulfate carriers.
