There are several analyses method in the cement and lime industry, to determinate an amount of CaCO3 during the thermal decomposition of rocks. The most uses the TGA-DTA and XRF and analysis (where the last one cannot give an absolute value of carbonate) in the meantime the petroleum industry swear to carbonate bomb analysis (Müller and Gastner, 1971). In this work I wish to present the comparison results between two analytical methods; acid decomposition and process of thermal decomposition of carbonate minerals. These two analyses are not important only for carbonate determination, during OPC clinker and lime production connected to dissociation of mineral waw material. At the same time they make possible control the amount of consumed heat energy in the process per unit of product. For this purpose we analysed some samples of flyschoid rocks from Anhovo area. The determination results of Mg carbonates with TGA-DTA, XRF, XRD analysis and results of acid decomposition of carbonates by carbonate bomb technique demonstrate a correlation factor of 0.97Pri spremljanju reaktivnosti karbonatnih kamnin je treba upoštevati njihove geološke danosti, kot sta struktura in tekstura. Obstaja več načinov določanja masnega deleža karbonata v kamnini; cementna industrija in proizvodnja apna uporabljata največkrat TGA-DTA in XRF analizo (zadnja ne podaja absolutne vrednosti), medtem pa naftna industrija prisega na t. i. hitro analizo, t. j. uporabo karbonatne bombe (Müller and Gastner, 1971). V prispevku želim predstaviti primerljivost med analiznima postopkoma, ki temeljita na kislinskem razklopu ter procesu termičnega razpada različnih kamnin. Analizi nista pomembni le za določitev masnega deleža karbonatov, omogočata tudi dopoljneno sledljivost porabe toplotne energije pri proizvodnji OPC-klinkerja. V ta namen so bili izbrani vzorci flišnih kamnin, ki nastopajo na področju Anhovega. Korelacija rezultatov med TGA-DTA, XRF in XRD analizo ter kislinskim razklopom karbonatne bombe je pokazala, da znaša za določitev Mg karbonatov s termično analizo in analizo karbonatne bombe, faktor korelacije 0,97TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
