Description
Technical field
The present invention relates to technical field of cement production, and in particular to a kind of bubble slag and its cement formula.
Background technique
Cement is powdery hydraulicity inorganic coagulation material, at slurry after adding water and stirring, can be hardened in air or in water
Middle hardening, and can the materials such as sand, stone are cemented together securely.Currently, in cement production process, usually by clinker, stone
Cream, slag and lime stone simultaneous grinding.And the compression strength of finished cement is mainly influenced by clinker strength, and other compositions meeting
It influences clinker strength to play, and then influences strength of cement.Meanwhile the problem of cement is in the production process, and coal consumption and material consume
It is very serious, to also be increased manufacturing cost in certain degree.Therefore, cost and enhancing strength of cement how to be reduced always
It is problem.
Summary of the invention
In view of the foregoing, it is an object to provide a kind of bubble slag and its cement formula, the water being prepared
Steep slag activity preferably, moderate strength is applied in cement preparation, and the cement quality obtained after proportion is more satisfactory, good strength.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of bubble slag, the original including following parts by weight
Material: 50-70 parts of silica, 15-25 parts of calcium oxide, 12-20 parts of aluminium oxide, 1-3 parts of magnesia, 6-10 parts of granulated slag.
Above-mentioned bubble slag further includes 2-4 parts of melilite.Preferably, addition can increase water to the activity of melilite in bubble slag
Steep the activity of slag.
The weight ratio of the silica and calcium oxide is (3.5-4.5): 1.Silica and calcium oxide are belonging respectively to
Acidic oxide and basic anhydride, it is required that the ratio of acidic oxide and basic anhydride total in bubble slag is not less than 1,
Because if acidic oxide content is higher, then the rate of set of cement and early strength enhancement rate are slack-off, and later strength can be shown
It writes and improves, and the corrosion resistance of cement can be enhanced.
The granulated slag is the mixture of metal granulated slag and nonmetallic granulated slag；Wherein, metal granulated slag and nonmetallic granulated slag
Weight ratio be (5-8): 1.
The metal powder cinder ladle contains following ingredient: 0.6-1 parts of potassium, 0.2-0.5 parts of manganous oxide, 4-7 parts of iron powder and vulcanization
2-4 parts of molybdenum.
The non-metal powder cinder ladle is containing following ingredient: 1.5-3 parts of phosphorus pentoxide.
Cement comprising above-mentioned bubble slag, the raw material including following parts by weight: 50-70 parts of clinker, 8-15 parts of gypsum, bubble
15-25 parts of slag, 3-5 parts of flyash, 6-10 parts of active addition.
The weight ratio of the bubble slag and flyash is (3-8): 1；Bubble slag is similar with the ingredient of flyash, enhances bubble
The reasonable weight ratio of bubble slag and flyash is added in cement after the active constituent of slag, it can be than adding the water of its single component
Mud intensity increases, and slows down being excessively used and bubble slag is become and abandoning to be precious for flyash.
Wherein, the adjustable cement performance of addition one side of active addition, increases yield；It on the other hand can also be with
Reduce cement cost.
Beneficial effects of the present invention: preferably, moderate strength can preferably be applied in cement system bubble slag activity of the invention
In standby, the cement quality obtained after proportion is more satisfactory, good strength, and setting time is shortened；And cement is in manufacturing process
In, the problem of substituting most flyash and other fillers using bubble slag, coal consumption and material consumption can be reduced, thus also certain
Degree on reduce manufacturing cost.
