Mineral blending material for producing PHC (Pyrolysis Hydrocarbon) tubular pipe free from high pressure steaming process as well as application

The invention discloses a mineral blending material for producing a PHC (Pyrolysis Hydrocarbon) tubular pipe free from a high pressure steaming process. The mineral blending material comprises the components in percentage by weight as follows: 60-80% of superfine blast furnace slag micropowder and 20-40% of desulfurization gypsum. According to the mineral blending material, the loss on ignition is less than or equal to 3%, the chlorine ion content is less than or equal to 0.02% and the water content is less than or equal to 1.0%. The mineral blending material provided by the invention is in particular suitable for preparing concrete for producing the PHC tubular pipe free from the high pressure steaming process and can replace 15-25% of cement equivalently. The prepared concrete has the advantages of high strength in early stage, continuous development of strength in later stage, good durability and the like. In the production process of the PHC tubular pipe, the high pressure steam maintenance link is omitte
