Abstract
It is main raw material with the coal gangue that the present invention proposes a kind of, adds an amount of agglutinate and activator, adopts impact briquetting, the colliery wastes brick that the natural curing method is produced.The same common brick of its physical dimension, solid.Characteristics on the prescription are: coal gangue accounts for 75%～84%.Product strength and frost resistance satisfy the requirement of No. 75 bricks among the existing standard GB 5101-85 " fired common brick ".
Description
The present invention relates to a kind of natural curing coal gangue brick, belong to industry and building materials for civilan use.
Traditional building brick is generally clay brick, forms with the coal roasting after going into kiln by the clay base.Its shortcoming is to destroy a large amount of farmlands and consume the more coal energy.There is a large amount of by product-coal gangues in the place that produces coal, both also contaminate environment of land occupation.Spoil had and was used for making building brick in the past, but mainly was system " sintering spoil brick ", still needed a large amount of coals, and the quality instability, and spoil can not all utilize.
The present invention proposes a kind ofly without clay, without the coal roasting, without steam curing, by the brick that natural curing is produced, reach and protect the fields, turn waste into wealth, save energy is eliminated the purpose of waste dump.The present invention also aims in addition reduce the brick cost, and the intensity of brick and frost resistance satisfy the requirement of No. 75 bricks among the existing standard GB 5101-85 " fired common brick " with few cement of trying one's best.
The same sintered common clay brick of the physical dimension of brick, solid.Can partly replace common brick to be used for industry and covil construction.
The prescription of brick of the present invention is: coal gangue+agglutinate+activator.Wherein, coal gangue accounts for 75～84%; Agglutinate cement, consumption is 15%, can replace 1～7% cement with flyash 2～12% when having ready conditions; Activator can be: lime, gypsum and calcium chloride, lime consumption 0～5%, gypsum consumption 0～2%, calcium chloride consumption 0.01～0.1%.
The used coal gangue of the present invention is the spontaneous combustion spoil preferably, also can be weathering cash or weathering cash not, its carbon content all ≯ 5%, spoil particle diameter ≯ 5mm; Cement adopt newly produce 425
#Silicate system cement commonly used.Material all should be milled to cement fineness except that spoil.Flyash must be loss on ignition ≯ 2%, SiO
2Content ≮ 50%, fineness are 0.080mm square hole sieve screen over-size ≯ 20%.
During production, above materials processing is become required granularity, cooperate, add suitable quantity of water stirring, rolling by the prescription metering, send the extrusion forming of ram-type brick press, about forming pressure 300KN, natural curing behind the adobe pile, rainproof antifreeze, suitably watering in 15 days, maintenance can be used after 28 days.
Major advantage of the present invention is: can consume a large amount of coal gangues, without clay, low without fuel, cement consumption cost few, brick, provide effective way for eliminating waste dump.
Act is now mixed flyash and is supplied to implement with two kinds of prescriptions not mixing flyash:
| Prescription | Coal gangue | Cement | Fine coal sand | Lime | Gypsum | Calcium chloride |
| I | 75 | 8 | 12 | 3.8 | 1.1 | 0.10 |
| Ⅱ | 84 | 15 | 0 | 0.7 | 0.3 | 0.05 |
Claims (3)
1, a kind of colliery wastes brick adopts impact briquetting, and the natural curing method is produced, and it is characterized in that in the proportioning raw materials, coal gangue accounts for 75～84%; Agglutinate cement, consumption is 15%, can replace 1～7% cement with flyash 2～12% when having ready conditions; Activator can be: lime, gypsum and calcium chloride, lime consumption 0～5%, gypsum consumption 0～2%, calcium chloride consumption 0.01～0.1%.
2, brick as claimed in claim 1 it is characterized in that the coal gangue in the raw material can be spontaneous combustion, weathering or unweathered, but its carbon content all should be below 5%.
3, brick as claimed in claim 1 or 2 is characterized in that the flyash in the raw material must be loss on ignition ≯ 2%, SiO
2Content ≮ 50%, fineness are 0.080mm square hole sieve screen over-size ≯ 20%.
