Abstract
A composite additive for increasing the blending ratio and the performance of cement is prepared from calcium feldspar, alunite, lime stone, gypsum, table salt, and sodium methylene bisnaphthalene sulfonate through calcining and pulverization, and features high effect.
Description
The invention belongs to the cement technology field, relate to a kind of cement industry additive.
At present, in the manufacture of cement, adopting traditional activity excitation theory mostly (is NaoH-Ca (OH)
2-CaSO
4Pattern) and traditional enhancing theory coach, in order to improve cement performance and blending amount of mixture material.But the exciting agent selectivity of traditional activity excitation theory is strong, poor reliability, poor effect; It mainly is according to the fusion gypsum that tradition strengthens theory---lime expands when hydrated cementitious and makes cement stone closely knit and gain in strength, owing to replace gypsum when using, be prone to the rapid hardening problem of cement, thereby its reinforced effects and not obvious, and also be difficult to control when using.Though the kind of cement additire is a lot of in the existing cement technology, as hardening accelerator, frostproofer, accelerating chemicals, anti-fissuring agent, water reducer, activity excitant or the like, but these additives have unicity more, even when improving a certain performance of cement, other performances to cement produce detrimental action, and complex function is poor.Vertical Kiln for Cement Production enterprise ubiquity yields poorly at present simultaneously, and is of poor quality, the cost height, and benefit is low, the key issue of new height on the difficulty.
The purpose of this invention is to provide a kind of composite additive that improves cement mixture volume and performance, thereby overcome the existing above-mentioned defective of present technology.
The objective of the invention is to excite theoretical and strengthen theory with tradition is foundation, and adopting neutral salt is activity excitant and toughener, and its main points are that its raw material and weight percent consist of;
Lime feldspar 12-40%
Alunite 17-40%
Wingdale 11-15%
Gypsum 9-15%
Salt 4-12%
Methylene radical two bitter edible plant sodium sulfonate 5-15%
Preferred raw material and weight hundred scores consist of;
Lime feldspar 18-35%
Alunite 20-38%
Wingdale 11-14%
Gypsum 10-13%
Salt 5-10%
Methylene radical two bitter edible plant sodium sulfonate 8-13%
Preferred raw material and weight percent consist of:
Lime feldspar 20-25%
Alunite 30-36%
Wingdale 11-13%
Gypsum 11-13%
Salt 5-7%
Methylene radical two bitter edible plant sodium sulfonate 10-12%
The production method of additive of the present invention is first to lime feldspar, alunite, Wingdale, gypsum fragmentation, calcines through 20-50 minute down at 1150 ℃-1300 ℃, makes 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 make additive of the present invention.
Additive of the present invention and cement clinker and blended material proportioning adopt (0.5-1.0): 100, when pulverizing cement, add.
Additive result of use of the present invention mainly embodies following 4 aspects:
1, improves strength of cement, improve cement performance.Intensity can improve more than 30% in three days, seven days, and intensity can improve more than 20% in 28 days.Eliminate free lime effectively.The drying shrinkage of cement, freeze-thaw resistance, wear resistance, impervious, anti-carbonization ability, corrosion resistance, cement color etc. is improved effectively.
2, increase the blended material addition content by a relatively large margin, improve cement output, reduce cement cost.
Reach under the 52.5MPa situation at clinker strength, the slag addition content can reach 50-70%; Slag, coal gangue, zeolite, flyash mixed dosage can reach 25-40%; Can reach 30-50% during the blended material blending; Stably manufactured 425#R cement can improve cement output more than 20%.
3, accelerate the warehouse compartment turnover, guarantee that soundness of cement goes out the break-in lattice.Under the square one, can improve a label and produce cement, guarantee the super design scale of production line.Every index meets GB175-92, GB1344-92, GB12958-91 requirement.
4, utilized industrial residues such as slag, slag, flyash, coal gangue by a relatively large margin, save energy reduces environmental pollution.Make cement production enterprise can enjoy the preferential policy of country.
Further illustrate the present invention with embodiment below.
Embodiment 1:
Lime feldspar 15%
Alunite 40%
Wingdale 13%
Gypsum 13%
Salt 5%
Methylene radical two bitter edible plant sodium sulfonates 14%
Earlier lime feldspar, alunite, Wingdale, gypsum are mixed fragmentation by above-mentioned formula rate, under 1200 ℃,, make these raw material react withs through 50 minutes calcining.Secondly, after the raw material that calcining is good carries out conventional grinding with salt, add methylene radical two bitter edible plant sodium sulfonates again to stir, promptly make additive of the present invention.
Embodiment 2:
Lime feldspar 20%
Alunite 36%
Wingdale 13%
Gypsum 13%
Salt 6%
Methylene radical two bitter edible plant sodium sulfonates 12%
Different is that temperature is controlled at 1300 ℃ to production process with embodiment 1., and the time was controlled at 20 minutes.
Embodiment 3:
Lime feldspar 23%
Alunite 35%
Wingdale 12%
Gypsum 12%
Salt 6%
Methylene radical two bitter edible plant sodium sulfonates 12%
Different is that temperature is controlled at 1250 ℃ to production process with embodiment 1., and the time was controlled at 30 minutes.
Further react Application of Additives effect of the present invention with example more below, the proportioning of described additive and cement clinker and blended material adopts (0.5-1.0): 100.Example one
According to the data of enumerating in the table one, with additive and grog and the common grinding of slag that the present invention the 3rd embodiment makes, different ingredients, three kinds of raw material consumptions are different.Wherein grog is 19.5-69.2%, and slag is 20-70%, and additive is 0.5-0.8%.Data can be seen from table, with the recipe ratio of grog and gypsum, the effect highly significant.
