Prikazana je mogu nost proizvodnje belog ekocementa primenom suve metode pri niskotemperaturnom pečenju sirovinske mešavine po sistemu CaO - SiO2 - AL2O3 - MgO. Urađeni su kompjuterski proračuni i izvršena je analiza zavisnosti karakteristika cementnog klinkera od kvantitativnog odnosa sirovih komponenti. Novi sastav mešavine sirovina sa smanjenjem od 19 tež. % količina karbonatne komponente i shodno tome određena je emisija CO2 pri sagorevanju. Uočene su osobenosti faznih transformacija u materijalu pri pečenju sa maksimalnom temperaturom od 1100°C pri uvođenju mikrotalkuma u početnu smešu sa formiranjem perikloza, okermanita i mervinita kao faktora u strukturi i svojstvima cementnog klinkera.Reference
