Method for producing geopolymer binding material by red mud and geopolymer binding material, and products

The present invention discloses a method of red mud produced by the geopolymer cementitious materials and products. Said method comprising the steps of: (1) uniformly mixing the red mud with a hydroxide of an alkali metal carbonate or alkali metal hydroxide or carbonate is added per kg of red mud containing 3 moles of an alkali metal element to 5 moles; (2) calcining the mixture from 1 to 3 hours at 700 deg.] C to 900 ℃, to obtain a thermal cooled - alkali activated red mud; (3) the activated red mud and granulated blast furnace slag at a mass ratio of 1.5: 1 to 4: 1 and mixed. Produced by the above method geopolymer binder, when mixed with a mass ratio of 60 to 70 percent water uniformly, forming conservation. The method, extensive use of Bayer alumina production of red mud waste, environmentally friendly, low cost. The product was stirred with water when used directly, without adding an alkaline activator such as water glass, good drying does not require molding or autoclave, easy to use, adaptability.
