Abstract
A kind of non-steaming silicate brick and method for making thereof, adopt various metallurgical slags, residue of chemical industry, cinder, sand, stone flour or coal dust ash to be main raw material, be aided with iron ore slag, lime, gypsum etc., through stir, roll, compression moulding, and form finished bricks through natural curing, can reach 100 label brick requirements.This brick cost is low, simple for production, and raw material sources are wide, be easy to promote.
Description
The present invention relates to a kind of non-steaming silicate brick and method for making thereof.More particularly a kind ofly utilize various sandstones, industrial metallurgical slag, mine tailing, and coal gangue or flyash is main raw material, dinas brick of making without vapor cure and preparation method thereof.
In application number is 89109385 Chinese patent application " free of calcining and steam curing flyash brick and preparation method thereof ", disclose and a kind ofly made free of calcining and steam curing flyash brick and method for making thereof by in flyash, adding lime and cement (or gypsum).Because the amount of lime that this brick adds and cement is all bigger, corresponding cost is also higher, replaces cement as adopting gypsum and Tai-Ace S 150, because Tai-Ace S 150 costs an arm and a leg, resulting cost is also very high.
Purpose of the present invention overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of with low cost, non-steaming silicate brick that raw material sources are wide, simple for production and preparation method thereof is provided.
Non-steaming silicate brick of the present invention by gather materials, iron ore slag (being commonly called as grain slag), lime and excitation material form.Gathering materials can be various sands, metallurgical slag, residue of chemical industry, cinder, mine tailing, flyash and stone flour, and excitation material is gypsum or sodium sulfate.The various proportioning raw materials of this dinas brick (per-cent meter by volume) are:
Gather materials: 70-78%
Iron ore slag: 15-20%
Lime: 6-10%
Gypsum: 0.5-1.5%(or sodium sulfate 0.1-0.2%)
The each component sum is 100%
The principle of selecting materials is: aggregate size should as surpassing 2cm, be pulverized in 2cm.The iron ore slag should be selected the new slag in half a year for use, and particle diameter should be in 0.5cm.The content of free calcium oxide should＞65% in the lime, preferably selects the calcium lime powder that dispatches from the factory in three months for use.Gypsum can be selected building gypsum plaster for use.
The effect of excitation material mainly is to accelerate calcify reaction, increases the early strength of brick, also can not add any excitation material, but needs to increase the natural curing time.
The making method of non-steaming silicate brick of the present invention is: will gather materials earlier, iron ore slag and lime powder by the requirement mixed, ageing 3-5 days.Add excitation material then and suitable quantity of water stirs, the material that stirs should comprise the water content of former each component at 15-23%(by the water ratio that accounts for weight of material per-cent).Through rolling, compression moulding (pressure＞150kg/cm then
2).Left standstill after the moulding 2-4 hour, and used the complete overspread of black plastic cloth again, natural curing 7-14 days (be seven days summer, and spring and autumn is 14 days), finished bricks.As not adding any excitation material, need natural curing 28 days.
Adopt the non-steaming silicate brick of made of the present invention, cost is low, simple for production.Can adopt various sands, metallurgical slag, residue of chemical industry, mine tailing, cinder or flyash is main raw brickmaking, and raw material is easy to get, and is easy to utilize.
Embodiment 1: river sand 70%, and calcium lime powder 10%, iron ore slag 20%, sodium sulfate 0.1%(is the per-cent meter by volume).Make by method for making of the present invention, adopt 60 tons of brick pressing machine compression mouldings, natural curing 7-14 days.Finished bricks can reach 100 label requirements.
Embodiment 2: cinder 78%, iron ore slag 15%, calcium lime powder 6%, terra alba 1%.Implement by aforementioned method for making.Finished bricks reaches 100 label brick requirements.
Embodiment 3: flyash 40%, river sand (or stone flour) 30%, iron ore slag 20%, calcium lime powder 10%, sodium sulfate 0.1%.Make by aforementioned method for making, finished bricks can reach 100 label requirements.
Claims (2)
1, a kind of non-steaming silicate brick, by gather materials, iron ore slag, lime and excitation material form, it is characterized in that gathering materials and be various metallurgical slags, residue of chemical industry, cinder, sand, stone flour or flyash, excitation material is gypsum or sodium sulfate, and the proportioning raw materials of this non-steaming silicate brick (per-cent meter by volume) is:
Gather materials: 70-78%
Iron ore slag: 15-20%
Lime: 6-10%
Gypsum: 0.5-1.5% (or sodium sulfate 0.1-0.2%)
The each component sum is 100%.
2, a kind of method for making of non-steaming silicate brick according to claim 1, it is characterized in that will gathering materials earlier, iron ore slag and lime part by the requirement mixed, ageing 3-5 days; Adding the water ratio that excitation material and water is stirred to material is the 15-23%(weight percent); Roll then, again compression moulding; Left standstill after the moulding 2-4 hour, and used the complete overspread of black plastic cloth again, natural curing 7-14 days.
