Preparation method of novel composite cementing material
The invention discloses a preparation method of a novel composite cementing material. The preparation method comprises the steps of firstly, weighing desulfurized gypsum, sodium silicate and calcium oxide according to a certain ratio, and carrying out mixed milling on the materials to obtain a composite superfine powder activator; weighing copper smelting slag and cement clinker according to a certain ratio, and milling the copper smelting slag and the cement clinker to be fine by using a small testing mill; and adding the prepared composite superfine powder activator into a milled copper smelting slag and cement clinker mixture, adding sodium metaaluminate as an activated aluminum additive, and carrying out secondary mixed milling by using the small testing mill to obtain the composite cementing material. The prepared cementing material is favorable in cementing and working performances, moderate in strength, small in environmental load and capable of substituting part of cement to fill metal mines.
