Application of perlite and waste of paper production for manufacturing of cement clinker

Abstract

The possibility of making cement clinker with the integrated use of natural raw materials of volcanic origin and waste from paper production (scope) has been studied. The analysis of the dependence of the composition of the raw mixture based on the system chalkperlite-scope on the specified characteristics of cement using the specially developed computer program "Clinker" has been carried out. The composition of the initial mixture for the manufacturing of cement clinker was determined with a quantitative ratio of perlite: scope=1:3.5 has been investigated. The features of the formation of the phase composition and properties of the binder during the firing of the raw mixture in the range of maximum temperatures 1200-1400 0C are shown.
