The aspect of reducing discharge of the carbon dioxide: when the mixing amount of phosphor slag is 10%, and the mixing amount of admixture material is increased from 30% to 50%, the discharge amount of CO2 can be reduced 36.39%.

• 二氧化碳减排方面:当磷渣掺量达到10%25；而在后期水泥复合时；将混合材掺量从原来的30%25提高到50%25后；可使CO_2减排率达到36.；39%25。
