preparation example Construction
[0055] Such as figure 1 Shown, a kind of preparation method of the restoration material of cement concrete building, specifically can comprise:
[0056] Step A, using alkali slag to prepare alkali slag composite calcined product.
[0057] Specifically, the corresponding step of using alkali slag to prepare the alkali slag composite calcined product may include:
[0058] In step a1, the alkali slag is mixed with an aluminum chromium phosphate binder accounting for 1.2% of the total mass of the alkali slag, so as to prepare an alkali slag mixture.
[0059] In step a2, stir the alkali slag mixture evenly so that the water content is not greater than 30%.
[0060] In step a3, the uniformly stirred alkali slag mixture is placed in a calciner, and calcined at 650° C. to 750° C. for 8 to 12 hours.
[0061] In step a4, the calcined alkali slag mixture is continuously stuffed in the calciner for at least 48 hours, and after natural cooling, the alkali slag calcined product is obtain...
