Method for producing 2#-line P.O42.5 cement with low coefficient of variation
The invention discloses a method for producing 2#-line P.O42.5 cement with low coefficient of variation. The method comprises the following steps: proportioning the following ingredients in parts by weight: 6.2 parts of limestone, 5.9 parts of fly ash and 5.4 parts of granulated blast-furnace slag powder; adding the limestone, the fly ash and the granulated blast-furnace slag powder into a cement mill in proportion, and producing the 2#-line P.O42.5 cement by a vertical-mill milling technological process. The method for producing the 2#-line P.O42.5 cement with low coefficient of variation, disclosed by the invention, can be used for overcoming the defects of complicated ingredients, unreasonable proportioning ratio, poor stability and the like in the prior art, thereby achieving the advantages of simple ingredients, reasonable proportioning ratio and good stability.
