Abstract
The invention discloses a building material product based on the synergic action between alkali and CO2 and a method for preparing the same, which belongs to the field of silicate building material and product thereof. In the building material product, the fly ash the fineness of which is controlled in the range of between 400 and 600m<2>/Kg and the slag form a mixed powder material, and an aggregate and water glass are added into the mixed powder material for forming so as to obtain a blank, and the blank is subjected to natural curing and carbonization to obtain the building material product. In the invention, the industrial waste slag is used as raw materials, the high-performance silicate product is prepared under the conditions of low alkali and not doping lime and cement clinker, so that the strength level is high, no scumming phenomenon occurs on the surface of the product, the release quantities of various toxic and harmful ions are far below the threshold value; moreover, the building material product has the advantages of good durability, strong freezeproof and weather resistance capabilities, and is suitable to be the building wall material. The invention has active effect on utilizing waste slag resources, saving energy and reducing emission.
Description
Technical field
The present invention relates to silicate building material and goods, relate generally to waste residue, alkali, CO
2For main raw material, do not mix the novel wall material that lime prepares.
Background technology
In China, industrial residues such as flyash, slag have become the sharp useless main path of cement concrete industry as blended material, the concrete adulterant of cement.According to statistics, China in 2006 cement concrete industry 3.1 hundred million tons of industrial residues of having dissolved account for 46% of national industrial residue comprehensive utilization total amount.From reducing CO
2The discharging angle is set out, and this is equivalent to few production or uses 3.1 hundred million tons in grog less, and grog per ton discharges 1 ton of CO approximately
2, the CO that then causes thus
2CER is about 3.1 hundred million tons.This shows that utilizing industrial residue to make blended material, adulterant also becomes the most effective CO of cement concrete industry
2The reduction of discharging measure.Yet, utilize industrial residue to make supplementary cementitious material (as blended material, adulterant) or be that alkali is when exciting the main raw material of gelling material with the industrial residue at bigger volume, must mix a certain amount of (2% to 50%, even higher) alkali-activator to excite the chemically reactive of waste residue, promote the quick performance (being referred to as the alkali shooting techniques) of its gelling property.These alkali-activators that mix might cause the weather resistance of concrete structure bad (as alkali), even also may cause the concrete engineering quality accident, have restricted popularization and the application of this technology in cement concrete industry; High volume alkali-activator also can cause the alkalimetal ion stripping that excites gelling material, the surperficial accumulation of salt in the surface soil and problem such as expensive, and having hindered with slag, flyash, kaolin is that the alkali of raw material excites the practicability of gelling material to use.Therefore, mix alkali-activator and a series of problems of causing, seriously restricted the alkali shooting techniques at more effectively utilization of waste as resource of silicate material field performance, CO
2The effect of reduction of discharging aspect.
On the other hand, the aluminium in the silicate cement gel material, silicate minerals in hydration process and hydrated product (as calcium hydroxide) very easily with water-soluble carbonic acid gas generation chemical reaction (being referred to as carbonization), generate lime carbonate and aluminium glue, silica gel.For Steel Concrete, should do one's utmost to avoid the generation of carbonization, because the fine and close passive film that the carbonization meeting causes causing rebar surface destroys, quicken steel bar corrosion, influence durability of structures.But for silicate product, the carbonization meeting significantly improves the physical and chemical performance of goods.This improvement effect is mainly reflected in: carbonized product (mainly referring to lime carbonate) is deposited in the hole, and the porosity of goods is reduced, and compaction rate improves, and correspondingly shows as the raising of intensity on macro property; The passage of sedimentary carbonized product meeting blocking portion hole, sealing ion migration, thus ion packet is rolled in the product, its stripping is reduced.Pay close attention to reduction CO in the whole world
2Under the background of quantity discharged, it is significant to utilize carboniogenesis to prepare material.It not only can carry out modification to material, and can also capture a certain amount of CO
2In recent years, people to utilize carboniogenesis to prepare with lime, carbide slag, slag etc. be the material and the goods of raw material.But its carbonation source is not the hydrated product of aluminium, silicate minerals, but calcium hydroxide or the contained calcium hydroxide of waste residue itself that the lime that mixes forms.As everyone knows, 1 ton of lime of every production is removed the CO of fuel draining
2Also discharge about 0.79 ton of CO outward
2, this greatly reduces the reduction of discharging meaning of such material and goods undoubtedly.More disadvantageously, because calcium content is had relatively high expectations, only have the waste residues such as carbide slag, slag can be as raw material at present, its raw material sources be very narrow; To matrix water content, compaction rate and conservation system (humiture, CO
2Concentration and dividing potential drop) require very strictness, and also exist goods from great deficiency.Therefore, the technology of utilizing carboniogenesis to prepare material and goods also needs also need obtain important breakthrough aspect raw material, the preparation technology, and this technology of performance is at waste residue utilization, capture CO conscientiously
2The effect of aspect.
