Description
Technical field
The present invention relates to a kind of composite gelled material.
Background technology
With the high speed development of World Economics, concrete has become the most commonly used Building wood of current civil engineering field
Material, it has the advantages that materials simplicity, good endurance, low cost, easily molding, compression strength are high.Cement is as production concrete
The development of one of main material it is also extremely rapid, China's cement output occupies No. 1 in the world for years.The life of cement
Production can give off substantial amounts of CO2、SO2、NOxDeng pernicious gas, while substantial amounts of dust is produced, huge pollution is caused to environment, and
And huge consumption is produced to the non-renewable natural resources such as lime stone.
Cement mainly have portland cement, Portland cement, portland slag cement, portland-pozzolan cement and
Portland fly ash cement etc..Portland cement is still most widely used cementing material in current mining engineering, but is existed
Cost is high, and adaptability is not strong, the shortcomings of the ratio of mud and narrow cement-sand ratio adjustable extent.
It is desirable to find a kind of green binder materials, meet environmental protection and economic requirement.
The content of the invention
It is an object of the invention to provide a kind of composite gelled material.
The technical solution used in the present invention is：
A kind of composite gelled material, it is made up of the raw material of following mass parts：15~20 parts of cement, 30~45 parts of miberal powders, 10
~25 parts of flyash, 10~20 parts of gypsum, 1~10 part of lime, 1~5 part of sodium carbonate, 1~5 part of water reducer.
Cement is 32.5 class g cements.
Miberal powder is ground granulated blast furnace slag.
The rank of miberal powder is S95 levels.
Flyash is I grade or II grade of F class flyash.
Water reducer is lignin sulfonate water reducer, naphthalene water reducer, melamine system water reducer, sulfamate system
At least one of water reducer, fatty acid series water reducer, poly carboxylic acid series water reducer.
The beneficial effects of the invention are as follows：
Composite gelled material prepared by the present invention greatly reduces the dosage of cement under identical intensity requirement, alleviates water
To the pollution of environment in mud production process, while this material, on the premise of usage amount identical with cement, intensity is 2 times of cement
More than, and be solid waste because the raw material used in the production process of material of the present invention is most of, make this product
Economic advantages are had more than cement.

Comparative example 1：
32.5 cement that binder materials used in this comparative example is bought by the market.
Experimental program is：
1st, composite gelled material is prepared by embodiment 1-4 formula, it is then equal with machine stirring 5 minutes, completely stirring with stirring
It is even, gelling agent is made.
2nd, by cement-sand ratio 1：4, take embodiment 1-4 binder materials and cement and with a collection of river sand and be put into mixer in right amount
In mix slowly 60s；
3rd, quantitative water is mixed, slurry is configured to 75% concentration, quickly stirs 90s；
4th, after pot wall surrounding slurry is scraped in pot, it is stirred for 30s；
5th, uniform slurry will be sufficiently mixed to be poured in 70.7*70.7*70.7mm mould points for 6 times；
6th, after test specimen has some strength, form removal, maintenance extremely regulation age in 20 ± 2 DEG C of environment is placed in, on request
Its 3d, 7d intensity is measured respectively.
Embodiment 1-4, the strength character of comparative example 1 are as shown in table 5 below：
The strength character of table 5 contrasts
| 3 days intensity (MPa) | 7 days intensity (MPa) | |

As can be seen from Table 5, binder materials of the invention its 3 days, the intensity of 7 days significantly increases than cement, and its intensity is extremely
It is twice of cement less, the dosage of cement can be reduced in use, strengthen economic performance.
The useless price for filling thing miberal powder of solid is 240 yuan/ton in the present invention, 160 yuan/ton of flyash, 500 yuan/ton of gypsum, water
Mud is 350 yuan/ton, and remaining is micro addition, and the green cementing material price that the present invention is calculated according to proportioning is 300 yuan/ton of left sides
The right side, it is per ton than at least cheap 50 yuan or so of cement, and on the premise of same intensity is required, such as 3 days intensity is in 2.0MP, water
The cement-sand ratio that mud needs is 1:4, and the binder materials cement-sand ratio of the present invention can be reduced to 1：10, its comprehensive economy compares cement
It is enhanced about more than once.
