By RachelAlexander At submit, the product of brick machine supported mainly on the use of raw materials for the cement and ordinary sand, fake unhorse combine(such as enlarged perlite materials, clay pottery material and fly ash stuff), natural aggregates(such as pumice stone, unstable slag and zeolite), heavy-duty waste lightweight aggregate(such as fly ash, cinder, coal self-generated , coke slag, distended slag slag and Ca beads) and other unhorse granulated aggregate.
1. : The more than 32.5 ordinary bicycle Portland cement, portland cement(GB175-1999) and Portland Slag Cement(GB1596-91), in the main used when the summertime production of slag . Should not be used pozzolana cement and fly ash cement.
SiO2 content of ash at all levels greater than 40, Al2O3 of more than 15, bulk denseness of 516 107kg m3, particle denseness 1800 2400kg m3. In superior general, should use Ca, dry fly ash, which Gray acirc; hellip; nbsp;and acirc; hellip; iexcl; for more than 13MPa potency grade blocks, which can only be used for fly ash acirc; hellip; cent; intensity dismantle of the stuff is not greater than 10MPa.
Second, : is the major power pit(CaC2) Preparation of run off generated when alkyne. Carbide slag and hydrous lime in the authorship and nature of synonymous, Ca(OH) 2 content normally 60-80(dry basis). Wet work system in China to take more than alkyne, high irrigate , concentrated by hastiness can be used. Carbide hair tinge blue, a cold-shoulder odor, but harmless. If there is no option to can be used freshly lime, in general do not use hydrated lime, lime if necessary to pre-grinding, fineness 0.080mm square up mesh sieve is not more than 25 margin. Requirements effective calcium oxide calcium oxide content is not less than 70, the high the better, if less CaO can step-up the lime content. Lime in the MgO lt;4, otherwise the production easy to burst. Power plants, chemical plants released lime waste, or shell powderise can also be used in target of carbide used.
4, Gypsum: Gypsum is available to want more than 65 Ca sulphate, also available phosphogypsum(phosphate plant food industry, solid waste, of which P205 content less than 3) instead.
5. slag: fly ash and its main components and the same ostensible density 600-900kg m3, particle denseness 1100-1800kg m3; loss on ignition system le; 20, MgO content of less than 4, CaO of less than 5, SO3 of less than 4, volume stableness test pass, particle size 0.16-10mm, the fineness modulus shall be between 2.4-4.2.
6. sand: According to the thinness modulus(Mx) can be divided into grainy sand(Mx is 3.7-3.1), spiritualist sand(Mx is 3.0-2.3), fine sand(Mx to 2.0-1.6) and fine sand(Mx to 1.5-0.7). This product fineness modulus of sand between Mx is 3.7-1.6, the mud should be less than 3, should take in the river sand.
7. beat: mystify or pebbles, the size of greater than 5mm, less than 8mm.
8. heavy-duty run off: including fly ash, slag, waste slag, tailings, slag, twist waste(slag brick, rest), coal and so on. The industrial run off residuum can be used in conjunction with its technical foul requirements are as follows: the residuum of ignition loss no greater than 20, SO3 le; 2, the residue of the sand of subatomic particle size 0.3-1.3mm, 0.1mm powderize of le; 20 the following may on behalf of the sand used; the remainder of the pose subatomic particle size of 3-15mm, mud content le; 3 when used instead of stupefy. The run off cycle of 13 weight loss.
Coal is the roof, floor and the seam in the rock. Coal is not a I rock, but a admixture of carbon paper stuff and rock, which there is unstableness, burning coal to spontaneous or after the use of dyed, unprompted is not a moderate coal demulcent of 0.8, boiled loss rate less than 5, ignition loss no greater than 5. Slag should be placed more than 6 months, SO3 of not more than 1, and may not have tear apart, widow’s weeds and so on.
Calcium high-temperature furnace slag is a whirlwind of liquidness slag, its temperature is usually in the 1200-1400 acirc; bdquo; fnof;, slagging from the fathom when I well over by water quenching, irrigate extinction break open into a 2-10mm of solidness particles of vitreous irrigate slaked slag as slag or liquidness Ca balance, also titled Slag, slag containing Ca and other active voice components CaO, SiO2 content is high, is still obstinate by the signal detection of non-active material. Calcium slag extinction by water extinguishing, the particles live within the cracks and intramural stress, big loose granule, moderate granule was very fresh, so use the atomic number 20 residue must be broken.
9. volcanic slag: a unstable volcanic eruption of the stuff, porous, jackanapes and toughness and warm features, better insulation, heat insulating material, vocalize insulant effectuate. Natural packing material denseness 580-800kg m3. Crushing strength 3Mpa around.
10. pumice: It is a natural lightweight combine. Packing denseness 350-800kg m3, suppression strength of 1.6Mpa. So, as their stifling strength low pumice stone, pumice piling wraps strength is not so high, but its good thermal insulation.
11. dismount aggregate: including clay, fly ash ceramic, perlite, Floating Beads, Shale, pumice, unstable slag line(GB T17431.1-1998) requirements, the uttermost ingrain diameter 10mm(fineness modulus of 2.3-4.0 is appropriate) with clay content lt;3.
12. JFS activator: JFS activator is one of the core material of this production, its full activation of fly ash, some of the potency of heavy-duty run off residuum will play a unhesitating role. Verified by production practise, JFS activator triple-crown, less , the use cost is not high, can importantly set off the action of fly ash and slag to better the density of the brick machine, impermeableness, frost underground, carbonation stableness, irrigate resistance and shrinkage verify, qualification the stuff significantly accrued effectiveness and enduringness.
