PHASE CALCULATIONS AND MIX EQUATIONS FOR HIGH IRON OXIDE CEMENTS ON AN EQUIVALENT BASIS

THE CALCULATION OF THE CLINKER PHASES AS WELL AS THE CALCULATION OF THE RAW MIXES OF IRON-RICH CEMENTS CAN, BY MEANS OF NIGGLI'S EQUIVALENT STANDARD AND KUHL'S LIME STANDARD, BE CARRIED OUT IN ESSENTIALLY THE SAME WAY AS THE CORRESPONDING CALCULATIONS FOR NORMAL PORTLAND CEMENTS. THE CALCULATION OF BROWNMILLERITE IN THE CASE OF IRON-RICH STARTS FROM THE ATOMIC EQUIVALENT NUMBER A = 1/2 ALUMINUM OXIDE, IN CONTRAST WITH NORMAL PORTLAND CEMENTS, FOR WHICH THE CALCULATION STARTS WITH THE ATOMIC EQUIVALENT NUMBER F = 1/2 FERRIC OXIDE. IN DETERMINING THE RAW MIXES FOR IRON-RICH CEMENTS IT WILL BE FOUND VERY USEFUL TO CALCULATE THE QUANTITY DICALCIUM FERRIC OXIDE BY MEANS OF THE EQUIVALENT NUMBERS FOR THE INDIVIDUAL RAW MATERIAL COMPONENTS. IN A CASE WHERE A RAW MIX HAS TO BE COMPOSED OF THREE RAW MATERIAL COMPONENTS, IT WILL BE APPROPRIATE TO CALCULATE, BESIDES DICALCIUM FERRIC OXIDE, THE QUANTITY DICALCIUM SULFATE OR THE LIME DEFICIENCY OF THE INDIVIDUAL RAW MATERIAL COMPONENTS. IN THIS CASE TWO MIX EQUATIONS ARE SUFFICIENT FOR CALCULATING THE MIX PROPORTIONS. /AUTHOR/
