Description
Technical field
The invention belongs to changing rejected material to useful resource Application Areas, particularly itself and preparation method of phosphorus slag-phosphorus tailing foam concrete building block.
Background technology
Foam concrete block is a kind of light weight and has some strength, has the building material of heat insulating and noise-proofing function simultaneously.Along with developing rapidly of economic construction and improving constantly of living standards of the people, the energy that consumes of building increases day by day, and it is particularly evident that wherein heating air conditioning energy consumption has accounted for the Xia Redong cryogenic region of significant proportion ， China, the energy-conservation developing direction that becomes current building materials.Therefore,, under the situation of current power supply anxiety, light building material becomes the main body of current building materials just gradually with its superior energy-saving effect.In recent years light building material, protection of the environment and ecology useless around energy-conservation, joint soil, profit, improve the aspect developments such as building materials function, make light building material have more wide market.
Along with exploitation and the utilization of phosphorus ore, phosphate rock resource increasingly dilution ，Yi Bei Ministry of Land and Resources can not meet one of 20 kinds of mineral of national economic development demand after listing 2010 in, classifies non-renewable strategic resource as.China's phosphate rock resource is abundant, but the 80%th, in, low-grade phosphate ore, mostly belong to high, the difficult collophanite selecting of foreign matter content, in order to meet the specification of quality of phosphoric acid by wet process to raw ore, must could meet phosphoric acid and high-concentration phosphate compound fertilizers Production requirement through cost-effective beneficiation enrichment, produce thus a large amount of mine tailings.From mining ore out, after ore dressing extracts useful matter, the overwhelming majority is accumulated all the year round and is deposited in tailing dam, not only takies tract, and may cause severe contamination and destruction to ecotope.Phosphorus mine tailing granularity is thinner, piles up a place, if meet heavy rain, washes away, and easily causes and causes security incident by Serious geological disasters.
A kind of industrial residue discharging when phosphorus slag is producing yellow Phosphorus by electric oven, its major ingredient is Calucium Silicate powder, often contains the objectionable impuritiess such as heavy metal cadmium, phosphorus, fluorine, a large amount of phosphorus slags still save as master with outdoor heap.Because phosphorus slag contains phosphorus, fluorine, when taking a large amount of soils, easily, by sleet leaching, rainwash polluted-water, periphery people's living environment has been brought and had a strong impact on.Therefore, how to turn waste into wealth by these two kinds of trade waste recyclings, the problem that has become people more and more to pay close attention to.
A lot of scholars take up research and utilization phosphorus slag, phosphorus mine tailing is made various industrial building materials, as phosphorus slag aerated concrete building blocks and the manufacture method (CN101328051A) thereof of the application of Chinese architecture Si Engineering Bureau, but in this patent, only utilized a kind of phosphorus ore waste material of phosphorus slag, in 2nd～3 pages, its specification sheets to product properties introduction, the concrete segment intensity that aforesaid method is manufactured is lower, and thermal conductivity > 0.1w/ (mk).A kind of phosphorous slag autoclave aerated concrete building block and the manufacture method (CN101608484A) thereof of Guizhou Yuanlong New Environment-Friendly Wall Building Materials Co., Ltd.'s application, but this method has also only been utilized a kind of phosphorus ore waste material of phosphorus slag, waste utilization rate is low, referring to its Instructions Page 3, product properties is tested and introduced, its average strength is only also 5.1MPa, thermal conductivity > 0.1w/ (mk).
Phosphorus mine tailing and phosphorus slag belong to the waste residue that phosphate rock resource utilization produces afterwards, much phosphorous chemical industry enterprise has this two kinds of industrial residues simultaneously, but in current disclosed technical scheme, there is no the report that both are fully utilized together, particularly there is no the method for the phosphorus mine tailing that a large amount of utilizations are thinner.And in the making method of existing disclosed foam concrete block, cement, aggregate consumption are large, and trade waste utilization ratio is not high, need to use air entrapment agent/foaming agent, causes cost of manufacture high, lack the market competitiveness.

Each component proportion of phosphorus slag-phosphorus tailing foam concrete building block of embodiment 16～19 is in Table 4, and described base-material is by phosphorus mine tailing, phosphorus slag, lime and cement composition, and described admixture is sodium sulfate (Na
2sO
4), sodium aluminate (Na
2al
2o
4) and water glass (Na
2siO
3) between two or three's mixture, the consumption of described admixture is 0.5% of described base-material quality, the consumption of described water is that the 0.3(ratio of water to material of the dry material quality of described base-material and described admixture composition is 0.3), described foam be take volume as measure unit, and the ratio of the consumption of foam and the total mass of other each components (total mass of base-material, admixture and water) is 1000ml/kg.
In embodiment 16～19, the preparation method of phosphorus slag-phosphorus tailing foam concrete building block is identical with embodiment 11～15.The building block of prepared phosphorus slag-phosphorus tailing foam concrete, its corresponding ultimate compression strength, unit weight, thermal conductivity are listed in table 4, and testing method is the same.From test result, can find out, the equal < 0.1w/ of thermal conductivity (mk) of the foamed concrete that embodiment 16～19 prepares, can meet the industry current standards (JGT266-2011) that is even less than each density rating, and pore is even, heat preservation and soundproof is effective, block strength is high, weight is little, meet < < foam concrete block JGT266-2011 > > standard, can better reduce building energy consumption.
The performance of each component proportion of table 4 and foam concrete block
Obviously, above-described embodiment is to be only the example that clearly explanation is done, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of therefore amplifying or change are still within the protection domain in the invention.
