Problems solved by technology

[0007] Existing concrete admixtures are slow to produce effects when added to concrete. When it is necessary to use concrete admixtures to quickly improve a certain performance of concrete, how to apply catalytic polymetallic oxygen clusters to concrete admixtures It is the key point of the present invention to make the concrete quickly improve a certain performance during the mixing and pouring process, shorten the time-consuming, and improve the work efficiency.

Embodiment Construction

[0026] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] Weigh 0.92g or measure 10mmol of thiosemicarbazide, and measure 40ml of methanol, dissolve thiosemicarbazide in methanol, mix well to obtain the bottom liquid, transfer the mixed solution to a three-necked flask, and place it in Use an alcohol lamp to heat the asbestos net, and make it react for 30 minutes with constant stirring. Weigh 1.21g or 10mmol of salicylaldehyde, and measure 10ml of methanol, dissolve the salicylaldehyde in methanol, mix well To obtain the addition solution, slowly pour the addition solution into the three-necked flask, continue heating and stirring, and reflux for 2 hours, when white crystals precipitate out of the reactant in the three-necked flask, stop heating, and place t...

Description

technical field [0001] The invention relates to the technical field of improving concrete performance, in particular to a preparation method of a concrete admixture based on polymetallic oxygen clusters. Background technique [0002] Concrete, referred to as "concrete" for short, refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by gel materials. Generally speaking, the term concrete refers to the cement concrete made by using cement as the cementitious material, sand and stone as the aggregate; mixed with water containing admixtures and admixtures in a certain proportion, and then stirred, also known as ordinary concrete. It is widely used in civil engineering. [0003] Cement, lime, gypsum and other inorganic cementitious materials are mixed with water to make the concrete mixture plastic; and then through chemical and physical chemical action to solidify and harden to produce strength, generally speaking, drink...
