Description
Technical field
The invention belongs to novel gelled material preparation fields, are related to the preparation method and its production of a kind of carboaluminates cement
Product.
Background technique
Agstone is the byproduct generated in Limestone mining and Machine-made Sand production, and main component is calcium carbonate, is had
The advantages that source is wide, grindability is high, stable components.At present all circles mainly using agstone as a kind of inert filler come using,
But lot of documents shows that agstone has cryptoactive.When agstone is spiked into portland cement, from
The calcium carbonate dissolved out in lime stone can be reacted with the aluminium phase hyrate in portland cement, generated calcium aluminate of hydrated carbon, thus changed
Kind substrate performance, but the rate of the reaction due to generating calcium aluminate of hydrated carbon under general condition is extremely slow, therefore do not obtain also temporarily wide
General application.
Synergistic effect based on calcium carbonate Yu aluminium phase material, current someone is by agstone and aluminum-containing phase supplementary cementitious material
It is used etc. compound substitution clinker, and has developed new product, such as limestone calcination clay cement.But since calcium carbonate belongs to difficult
Soluble substance, solubility is extremely low, and the aluminium phase content in common cementitious material is limited and poor activity, needs to be excited for a long time by alkali
Could slowly it come Aluminum, therefore currently for the chemical activity application and development of calcium carbonate, also in the stage of very shallow-layer.
The agstone even nanometer of the limit is such as ground using calcium carbonate superfine powder by current accessible process conditions

GB/T 17671-1999 tests its compression strength at 3,28 days respectively.
Specific test result is as shown in table 1:
Table 1 is the detected intensities of each embodiment and reference examples,
The comparison of the detected intensities of each embodiment of table 1 and reference examples
As shown in Table 1, the carboaluminates cement (embodiment 1~12) being prepared by means of the present invention is due to being easy
The hydrated product of calcium aluminate of hydrated carbon is formed, therefore the development of its early strength is fast, the cement being better than in the reference examples 1~2 of use,
And intensity of the carboaluminates cement in the later period is not in retraction, still has quite high intensity, in materials for wall, plastics
Or the fields such as gum filler, building coating, fire resistant coating have a wide range of applications.
In addition the preparation method of carboaluminates cement provided in the present invention is relatively easy, easy to operate, forges without high temperature
It burns, convenient for promoting, while raw material sources are extensive, cheap, and the carbonic acid calcium substance such as lime stone is not required to big model in preparation process
High-temperature calcination is enclosed, so that CO2 emissions are low, is reduced environmental pollution.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
Scope of the claims in.
