Abstract

The self-curing mixture has the following composition in parts by weight:   refractory filler 100   sulphite liquor 4 to 8   hydrogarnet 2 to 5 Hydrogarnet is described by the formula 3CaO.Al2O3.XSiO2.YH2O, where X = 0.01-0.25, Y = 1.3-1.7. Provision is made for the addition of water-soluble phosphates in an amount from 0.03 to 0.50 parts by weight. <??>The self-curing mixture can be used for the individual or short-run production of medium-sized and large castings made of cast iron, steel, copper alloys, aluminium etc.
