Method of producing a cement with reduced content of chromium |
| abstract |
Present invention relates to the method of producing a cement with reduced content ofnchromium, where 0.01 to 10% by weight of mechanically and/or thermally treated ironncarbonates are used as iron correction component for the raw meal, with its subsequentnburning at the temperature from 1400 °C to 1500 °C, thus achieving primary reduction ofnCr VI in cement between 0.5 and 20 ppm of Cr VI . Such prepared cement receives duringnand/or after grinding chemically treated - activated iron carbonates in amount of 0.01 ton1% by weight, thus achieving final reduction of Cr VI in cement less than 0,5 ppm. |
