AbstractAbout the AuthorReferences
This work is devoted to the investigation of the possibility to obtain highstrength autoclave extruded products on the basis of wastes of molding masses according to the CHMmethod used in casting in ferrous metallurgy. The issues, connected with the influence of the activity of the calcquartz binder both on the phase composition of hardening products and on the final strength of the obtained material, are considered. With the help of xray diffraction and derivatographic analysis, it is found that the binder is mostly made up of lowbasic calcium hydrosilicates and an explanation to this phenomenon is given. The optimal activity of both the binder and the molding mixture has been established. In the course of the work it was established that these wastes can be a very valuable raw material for manufacturers of autoclave hardening products
