Abstract

The invention discloses a kind of composite gelled material.The binder materials is made up of following raw material:Cement, miberal powder, flyash, gypsum, lime, sodium carbonate and water reducer.Composite gelled material prepared by the present invention is under identical intensity requirement, greatly reduce the dosage of cement, alleviate the pollution to environment in cement production process, this material is on the premise of usage amount identical with cement simultaneously, intensity is more than 2 times of cement, and it is solid waste because the raw material used in the production process of material of the present invention is most of, this product is had more economic advantages than cement.

Description

A kind of composite gelled material
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.
Embodiment
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.
Preferably, cement is 32.5 class g cements.
Preferably, miberal powder is ground granulated blast furnace slag.
Preferably, the rank of miberal powder is S95 levels.
Preferably, flyash is I grade or II grade of F class flyash.
Preferably, water reducer is lignin sulfonate water reducer, naphthalene water reducer, melamine system water reducer, amino At least one of sulfonate based water reducer, fatty acid series water reducer, poly carboxylic acid series water reducer;It is further preferred that water reducer For naphthalene water reducer.
Present disclosure is described in further detail below by way of specific embodiment.
In the following example, cement is 32.5 class g cements, and miberal powder is S95 level ground granulated blast furnace slags, and flyash is I grade of F class powder Coal ash, water reducer are naphthalene water reducer, and remaining raw material is the common raw material in this area.

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
