Abstract
The present invention discloses a cement intensifier which relates to the technical field of cement. The technical problem to be solved is to provide a new cement intensifier with simple preparation and good use effects. The cement intensifier comprises the following raw materials of the percent proportion of weight: 40 to 70% of aluminium sulfate, 8 to 25% of silicon dioxide, 10 to 20% of alumina and 10 to 20% of table salt. The present invention is used for cement production to greatly improve cement strength and improve the parameter sum of mixed materials, such as slag, zeolite, flyash, coal gangue, furnace cinders, etc. Industrial waste is preferably used in raw material use. The present invention has the advantages of energy saving effect, environmental protection effect, simple preparation technology and little productive investment, and is favorable to popularize and use.
Description
Technical field the invention belongs to the cement technology field, relates to a kind of cement intensifier.
Disclosed No. 98110360 Chinese patents of background technology, its name is called " a kind of composite additive that improves cement mixture volume and performance ", this patent disclosure a kind of composite additive that is used for cement.In this technology, additive is obtained by following method:
(1) raw material and weight percent are: lime feldspar, 12-40%; Alunite, 17-40%; Wingdale, 11-15%; Gypsum, 9-15%; Salt, 4-12%; Methylene radical two bitter edible plant sodium sulfonates, 5-10%;
(2) with lime feldspar, alunite, Wingdale, the gypsum fragmentation of above proportioning, 1150-1300 ℃ of process calcination in 20-50 minute down, make these raw material react withs, secondly, after the raw material that calcination is good carries out conventional grinding with salt, add methylene radical two bitter edible plant sodium sulfonates again and mix, promptly obtain additive.
This technology discloses a kind of composite additive that is used to improve cement mixture volume and performance, and its advantage is to improve strength of cement, improves cement performance, improves the blended material addition content, reduces cement cost etc.Its technical essential is the composition and the weight percent of raw material, and technologies such as the calcination, grinding of preparation.The problem that this technology exists is that raw materials used kind is many, cost is high, complicated process of preparation.And wherein contained methylene radical two bitter edible plant sodium sulfonates belong to a kind of buck agent, though itself can improve strength of cement, it uses the back to form alkali to gather materials, cause the corrosion and the destruction of cement concrete, and its cost height.
Summary of the invention technical problem to be solved by this invention is, provide a kind of new, component is simple relatively, reasonable mixture ratio of components, lower, the simple cement intensifier of preparation technology of cost, in order to improve strength of cement, improves cement performance, improve the blended material addition content, reduce cement cost.
The main points of technical scheme of the present invention are the weight percentage between choosing of component and each component, and material component of the present invention and weight percentage are:
Tai-Ace S 150 40-70%
Silicon-dioxide 8-25%
Aluminum oxide 10-20%
Salt 10-20%
Preferred material component of the present invention and weight percentage are:
Tai-Ace S 150 45-60%
Silica 1 2-23%
Aluminum oxide 10-18%
Salt 10-18%
More preferred material component of the present invention and weight percentage are:
Tai-Ace S 150 48-52%
Silica 1 7-22%
Aluminum oxide 12-16%
Salt 12-16%
Above material component, through routine mix, the crushing and grinding process, granularity reaches specific surface area 80-100 and promptly obtains toughener of the present invention.When this toughener uses, with the weight percentage of cement clinker and blended material be 0.5-0.8%.
Another characteristics of the present invention are the selecting for use of raw material, give one's full attention to environmental issue on raw material is selected for use, preferentially select industrial waste for use.Aluminum oxide and silicon-dioxide obtain from power plant's waste material coal ash, and flyash is power-plant flue gas primary dust removing waste material, and the flyash major ingredient is silicon-dioxide (about 47%) and aluminum oxide (about 40%), and it is spherical that flyash is shaped as particle, and is mobile strong; Salt is selected salt slurry for use, selects the industrial waste after Weifang, Shandong Marine Chemical Industry Group produces for use, and its major ingredient is a sodium-chlor.
According to selecting for use of above material, component of the present invention and weight percentage are:
Tai-Ace S 150 40-70%
Salt slurry 10-25%
First level flour coal ash 20-50%
Advantage of the present invention and effect are:
The present invention makes full use of high reactivity mineral material, organic element and inorganic elements, particularly ingeniously select for use industrial waste (as the utilization of flyash and salt slurry) processing formulated, the abundant lateral reactivity of some industrial residues such as activated slag, boiling slag increases the content of the early strong mineral of cement.Use this toughener not only to improve the early strength of cement, but also help the growth of later strength.Its advantage is in particular in:
1, through evidence, the present invention can increase substantially strength of cement, and intensity GB can improve more than 20% in 3 days, 7 days, 28 days intensity (GB, ISO) can improve more than the 20-15%, equal to improve cement one-level label, the drying shrinkage of cement, corrosion resistance, cement color are all effectively improved.
2, behind use the present invention, the volume summation of blended materials such as slag, zeolite, flyash, coal gangue, slag can reach 50-60%, and cement still can reach original intensity and national every technical indicator, reduces the manufacture of cement cost greatly.Because a large amount of industrial residues such as slag, zeolite, flyash, coal gangue, slag that use reduce the use of cement clinker, play good environmental protection and energy-saving effect.
3, cement reaches same fineness behind use the present invention, can reduce the grinding time, guarantees that soundness of cement goes out the break-in lattice, accelerates the warehouse compartment turnover, under square one, can improve a label and produce cement, and every index meets the GB requirement.
4, the present invention preferentially selects industrial waste for use on raw material is selected for use, has effects of energy conservation and environmental protection.
5, preparation technology of the present invention is simple, and the production less investment helps promoting the use of.
