Preparation method of composite single-component alkali-activated cement cured at room temperature

The invention discloses a preparation method of composite single-component alkali-activated cement cured at room temperature. Raw meal powder is prepared from raw material containing a silicon-aluminum oxide, dolomite sodium carbonate and the like through mixing and ball-milling, wherein the charge ratio meets the conditions that the molar ratio of (CaO+MgO)/SiO2 is 1.0-2.1 and the molar ratio of (Na2O+K2O)/SiO2 is 0.3-0.7; the raw meal powder is calcined at 1100 DEG C for 2-3 hours, thus obtaining a clinker; and 10-30 parts of slag, 5-15 parts of slaked lime and 10-60 parts of gypsum are added to 100 parts of the clinker and the mixture is evenly mixed and ground, thus obtaining the cement. The cement prepared by the method has high early-high-strength, and especially has good long-term strength which is obviously superior to that of the prior art; the cement does not crack after being cured for a long period of time; the problem that the existing cement is easy to crack or break at the later period is solved; the raw materials are available; particularly, the proportions of cheap raw materials are high; the production cost is effectively reduced; and the composite single-component alkali-activated cement is simple in preparation method and convenient to use and maintain, and has good application value.
