In the alkali-activated activation reaction, Na is generally used2O and SiO2The content of (A) is measured to determine the amount of the effective component having the excitation activation effect in the alkali-activating agent.
The waste glass generally comprises: the waste glass mainly provides silicate active ions, the particle size of the preferred waste glass powder is not less than 300 meshes, and the smaller the particle size is, the more the silicate active ions are dissolved out, and the application is facilitated.
The waste glass and alkali metal hydroxide are used as alkali activator, and the alkali activator is mixed with common solid alkali activator such as: compared with the mixed alkali activator of sodium silicate and sodium hydroxide, the solid sodium silicate is time-consuming when dissolved, and the alkali activator can activate silicate or aluminosilicate in solid waste by simply adding water, so the alkali activator is easy to apply and saves time; the alkali activator does not need thermal excitation, and saves energy.
When the waste glass and the alkali metal hydroxide are used as solid alkali excitant, the action mechanism after adding water is as follows: the alkali metal hydroxide dissolves rapidly in water to form a large amount of OH with strong ionic power-Ions, decomposing solid waste; the waste glass is partially dissolved in a high-alkaline medium, and active substances such as sodium silicate and the like can be generated to replace the sodium silicate to be used as an alkali activator.
A base-activated cementitious material, comprising: 12-60 parts by weight of component A, 40-88 parts by weight of component B and 30-100 parts by weight of component C.

Preferred component a of this embodiment further comprises: a solid additive; the solid additive is: one or a mixture of any more of superplasticizer, corrosion inhibitor, filling material, ordinary Portland cement and bentonite; the addition amount of the solid additive is 15% of the component A. Solid additives can further improve the properties of the alkali-activated cementitious material.
From the perspective of sustainability, 90% of carbon footprint of a general alkali-activated cementing material comes from sodium silicate used in an activator, and waste glass powder is used as the alkali activator, so that the workability of the alkali-activated cementing material can be improved, the carbon footprint of the alkali-activated cementing material can be reduced, and the alkali-activated cementing material has important application significance.
In order to prepare the alkali-activated cementing material in the technical scheme, the preparation method comprises the following steps: step one, taking the component A and the component B in parts by mass in the technical scheme, and uniformly mixing to obtain an alkali activator and a solid waste mixed solid; and step two, adding the component C in parts by mass according to any technical scheme into the mixed solid obtained in the step one, and uniformly stirring to obtain the alkali-activated cementing material.
