Abstract
The invention discloses a kind of is raw material with the industrial residue, without calcining and the steam-cured processing method that forms various building blocks, it is to be jointing compound with the magnesium oxychloride, slag or flyash are main component, add bittern and modification mix, with the mechanical presses or the moulding of vibrating, promptly become the various building blocks that suitable intensity is arranged through natural curing.Compared with prior art, the present invention simply, does not need high-temperature steam curing, saves investment, very easily promotes the use of industrial residue utilization rate height, technology.
Description
The invention belongs to the manufacturing process of material of construction, particularly is that main raw material is without calcining and the steam-cured processing method of making various building blocks with the industrial residue.
A large amount of flyash serious environment pollutions of thermoelectric power station discharging, destruction farmland, people need utilize the clay firing brick-and tile on the other hand, are used for building, and the excavation of these clays has equally seriously destroyed the soil, has influenced the exploitation of ploughing.Therefore fully utilize the flyash substitute for clay and make the problem that material of construction becomes people's care.The existing method of utilizing flyash to make silicate lock, gas concrete is to add raw materials such as cement, lime, gypsum in flyash, also must just can reach the intensity that needs through high-temperature steam curing, complex technical process, and the high-temperature steam curing facility investment is big, has influenced popularizing of this technology.
The purpose of this invention is to provide a kind of processing method that produces the various fly ash building blocks of sufficient intensity, energy load-bearing at normal temperatures and pressures.
The present invention is achieved in that with slag and flyash be main raw material, is jointing compound with the magnesium gelatinous material of rapid hardening high-strength, is equipped with suitable material modified again, in process of production, without sintering and steam-cured, only natural curing under normal temperature, normal pressure makes the goods setting and harden.Concrete proportion scheme is: with magnesium oxychloride is jointing compound, is benchmark by the activity (being effective MgO content) of magnesium oxychloride, complies with desired product properties, as unit weight, intensity, water tolerance, weather resistance etc., designs goods food ingredient and consumption.By weight percentage, magnesium oxychloride gets 1, and slag or the flyash amount of getting are 1～4, saltwater brine (MgCL
2) 18～28 ° of Be of concentration are suitable, get 0.8～1.4, and are material modified (as Fe FeCL
3, H
3PO
4, H
3BO
3And soluble resin etc.) consumption is 0.01～0.02, and wherein magnesium oxychloride and halogen powder (liquid) should meet the specification of quality of standard GB 672-78 and GB2275-80 respectively, and flyash and slag silicon oxide-containing, the aluminum oxide total amount should be greater than 60%.
The moulding process of goods, by moulding mode difference, adopt the mixture of differing temps, as the mechanical presses or the moulding of vibrating, then adopt the dryness ingredients mixture, promptly the liquid consumption is 20～40% of a dry mixture in the mixture, concrete steps are after puddling slag or flyash, magnesium oxychloride evenly in proportion, spray saltwater brine, after brute force stirs, the mechanical presses or the moulding of vibrating; As manual assembly, then adopt the plasticity ingredients mixture, promptly the liquid in the mixture (comprising blender and water) consumption is 40～50% of a dry mixture, step is: magnesium oxychloride and saltwater brine are mixed into clean slurry, be sprinkled into flyash or slag then, the powerful stirring pours into mould again.After treating initial set after the moulding, cut natural curing then before the final set.
Can make 1. flyash or slag brick as required; 2. double hole hollow brick; 3. diplopore holllow building block.
The advantage of processing method of the present invention is:
1, makes full use of industrial residue, in the proportioning raw materials, flyash and slag content are 1～4 times of magnesium oxychloride, account for 50～80% of gross weight, maximally utilise industrial residue, after the popularization, the waste residue that is expected to properly settle thermoelectric power station is handled a difficult problem, also can thoroughly solve the situation that takes the clay system of baking bricks watt simultaneously.
2, owing to be jelling agent with the magnesium oxychloride, its chemical ingredients is a magnesium oxide, again with saltwater brine in magnesium chloride or sal epsom etc. be mixed mutually, ultimate compression strength after the sclerosis is up to 147MPa, and all contain active silica and active aluminium sesquioxide in the industrial residue, magnesium oxychloride is had modifying function, make magnesite product not only strengthen but also water-fast, anti-ly freeze, durable, thereby excellent product performance.
3, owing to above reason, adopt natural curing, do not need specific installation, reduce investment outlay, simplify technology, very easily promote.
Details of the present invention is further specified by following examples:
Example one, semi-drying ingredients mixture are manufactured brick and hollow brick and holllow building block
Take by weighing magnesium oxychloride and (contain magnesium oxide 90%, the efficient oxidation magnesium is 84%) 100kg, it is 98kg that flyash 294kg(wherein adopts 1/3 slag powders), fully puddle evenly after, spray saltwater brine (magnesium chloride solution proportion be 1.22 i.e. 26 ° of Be) 170kg(and wherein contain FeCL
31.0kg), taking mechanical presses or the moulding of vibrating after powerful mix is even,, can use after 7 days or 14 days through normal temperature, normal pressure, natural curing.
Example two, plasticity ingredients mixture are manufactured brick and hollow brick and holllow building block
Take by weighing magnesium oxychloride (contain magnesium oxide 87%, the efficient oxidation magnesium is 80%) 100kg, 180kg(wherein contains H with saltwater brine (magnesium chloride solution proportion be 1.18 promptly 22 ° of Be)
3PO
40.6kg), puddle clean uniformly slurry, be sprinkled into 240kg flyash then successively, brute force stirs, make it to have the needed denseness of construction, in mould, build moulding, by the time before the initial set final set later on, wipe off or cutting, can use after 7 days or 14 days in natural curing under normal temperature, the normal pressure after the off-type.
In construction, should note:
If the dried wet degree or the denseness of 1 ingredients mixture do not conform to when construction requirement, then can adjust saltwater brine concentration earlier, then increase and decrease the consumption of saltwater brine;
2, extrusion molding is to adopt the brick press of manufacturing hollow brick to carry out;
3, the moulding of vibrating adopts plate vibrator or vibrating spear to carry out;
Also need adopt vibrator to carry out slight vibrating during 4, with the moulding of plasticity slip.
The prepared goods of above-mentioned example have good physics, mechanical property, and its leading indicator is as shown in the table: (carried forward)
