Abstract
The present invention relates to a mixing excitation agent for raising the blending amount of mixture materials in cement, which uses calcined gypsum, calcined alunite and sodium sulfate as raw materials; the mixing excitation agent is manufactured by that the raw materials are respectively ground into particles, and the particles are uniformly mixed according to the proportion. The mixing excitation agent has the advantages of wide source of raw materials, reasonable prescription, low price and energy saving; the mixing excitation agent can effectively excite the activity of cement, so the blending amount of mixture materials in the cement is greatly enhanced; the mixing excitation agent is favorable for reducing the using amount of calcined materials, so economic benefits are increased.
Description
The invention belongs to building material technical field, relate to a kind of mixing excitation agent that improves blending amount of mixture material in the cement.
In the nearly many decades, because energy shortage in the world wide, energy-conservation problem has become an important content of cement science.The cement that utilizes blended material production few (nothing) grog polyhybrid material and have label height, excellent property has caused people's great attention, and it helps reducing the grog consumption, and save energy and resource consumption reduce the manufacture of cement cost.China's manufacture of cement major part is a vertical kiln operation, burn till (the grog label is less than the 55MPa) of low quality of grog, directly affect the volume and the cement output of blended material, for example: in the 425# slag cement, scoriaceous volume only is 25-30%, in the 425# pulverized fuel ash cement, the volume of flyash only is 15-20%, how on the basis of existing grog, improve the volume of blended material in the cement to greatest extent, reducing production costs, increase cement output, is an important technology difficult problem that needs solution at present.Data report was once arranged with some grinding aid and grog, slag, the common grinding of gypsum, by improving scoriaceous grinding fineness, reach the purpose of mixing blended material more.But because used grinding aid mostly is fluid organic material, the price height, the source does not have guarantees yet, produces to implement comparatively difficultly, and the strictness that its kind and addition all are subjected to national standard limits.Report is also arranged with some inorganics and blended material, grog, the common grinding of gypsum, reach the purpose that improves blending amount of mixture material in the cement.Because used inorganics is generally CaCl, NaCl, NaCO etc., though to improving blending amount of mixture material certain effect is arranged, its a large amount of Cl, Na etc. can have a negative impact to the weather resistance of cement concrete.
Task of the present invention provides that a kind of raw material sources are wide, prescription, production technique is simple, price is low, improve the effective mixing excitation agent of blending amount of mixture material in the cement, improve the blended material ratio greatly, few using not even with the complete qualified cement of grog production, reduce energy consumption and production costs, increase output, increase the benefit, thereby overcome the above-mentioned deficiency of existing in prior technology.
Task of the present invention realizes with following technical scheme: its exciting agent is a raw material with the plaster of Paris, calcined alunite and saltcake, and proportioning is: the plaster of Paris: calcined alunite: saltcake=50～68: 20～35: 6～17.And best proportioning is: the plaster of Paris: calcined alunite: saltcake=58～62: 25～30: 10～14.
Production method by above-mentioned said exciting agent is: the plaster of Paris, calcined alunite and saltcake are broken into fine granularity respectively, and mixing promptly gets exciting agent of the present invention in proportion.
Mixing excitation agent raw material sources of the present invention are wide, and prescription rationally, production method is simple, price is low, is used for manufacture of cement, and excited cement material activity improves blending amount of mixture material effectively.Usage ratio is that the exciting agent of 5-10% and macro-mixing material and small quantity of clinker are mixed into mill and promptly can be made into the cement that meets national standard.Help reducing the grog consumption, save energy increases turnout, increases economic efficiency.
The invention will be further described with embodiment below:
Embodiment 1: by the plaster of Paris: calcined alunite: the proportioning and the aforementioned production method of saltcake=59: 35: 6 make mixing excitation agent, in exciting agent: slag: the cement that the ratio of grog=8: 50: 42 is produced, after measured, resisted folding/ultimate compression strength (MPa) to be respectively 5.32/25.4,7.85/43.3 and 9.73/65.7 in 3 days, 7 days and 28 days; In exciting agent: slag: the cement that the ratio of grog=8: 60: 32 is produced, 3 days, 7 days and 28 days anti-folding/ultimate compression strength (MPa) are respectively 4.88/22.4,7.68/38.7 and 8.90/61.6; In exciting agent: slag: the cement that the ratio of grog=8: 70: 22 is produced, 3 days, 7 days and 23 days anti-folding/ultimate compression strength (MPa) are respectively 5.22/23.2,7.02/36.1 and 9.15/53.4.From last column data as can be seen, use 8% mixing excitation agent, fine slag contents brings up to 50% and 60% by 25% in the cement, compares with the Portland blast of common proportioning, and its performance does not only descend, and improvement is in various degree arranged on the contrary.Fine slag contents brings up at 70% o'clock, and 28 days intensity also approach the level of grog.
Embodiment 2: by the plaster of Paris: calcined alunite: the proportioning and the aforementioned production method of saltcake=50: 33: 17 make mixing excitation agent, in exciting agent: flyash: the cement that the ratio of grog=6: 40: 54 is produced, anti-folding/the ultimate compression strength (MPa) in 3 days, 7 days and 28 days is respectively 5.0/26,6,6.08/33.95 and 8.5/54.8.This result shows, adds 6% mixing excitation agent, and the strength property that doping quantity of fly ash is improved 20%, 3 day, 7 days and 28 days all is better than the Portland fly ash cement of common proportioning.
Embodiment 3: by the plaster of Paris: calcined alunite: the proportioning and the aforementioned production method of saltcake=68: 20: 12 make mixing excitation agent, in exciting agent: slag: the cement that the ratio of slag=10: 32: 58 is produced, anti-folding/the ultimate compression strength (MPa) of its 3 days, 7 days and 28 days is respectively 5.37/27.2,6.08/36.5 and 7.5/51.2, promptly show under the situation of no grog and gypsum, add this exciting agent 10%, its performance index also meet 425# dross slag cement GB13590-92 standard fully.
