Abstract

The present invention relates to a baking-free waste slag brick which comprises the raw materials: 36 to 43% of building waste slag, 44 to 51% of inferior rock and 12 to 20% of cement, wherein the cement is added with 1 to 2 wt% of water reducing agent; the baking-free waste slag brick can also comprise the raw materials: 38.5 to 39.5% of building waste slag, 46.5 to 47.5% of inferior rock, 5.5 to 6.5% of cement, 3.5 to 4.5% of fly ash and 3.5 to 4.5% of calcium oxide. The present invention has a manufacturing method that the building waste slag and the inferior rock are respectively crushed and ground into powder materials, the raw materials are proportioned, stirred and mixed, the mixture is pressed to form green bricks under the pressure of 170 to 200 kilograms/ square centimeter, and the green bricks are placed and cured for more than 15 days at the air temperature of more than 0 DEG C. As the brick uses the building waste slag as the principle raw material, the treating problem of the building waste is solved, and the cost is saved; the formulation materials can solidify to meet the hardness requirement after being cured at ordinary temperature, the energy saving effect is obvious, and the yield is high; the radioactivity and the hardness of the brick achieve the Chinese standards, and other properties are good. The present invention has the advantages of curing at ordinary temperature, energy consumption reduction, equipment simplification, compression forming, easy demoulding, easy flow-line production realization, large green brick strength, high yield and direct stacking and deposition.

Description

Unburned Industrial Residue Brick and preparation method thereof
(1) technical field
The present invention relates to a kind of building block and preparation method thereof, be specially a kind of unburned Industrial Residue Brick and preparation method thereof.
(2) technical background
Traditional clay brick is taken a large amount of clays and is fired, and power consumption is high, ruins the field and takes up an area of unfavorable environmental protection.And general cement brick adopts rock ballast, sand, cement and chemical additive to add water stirring vibratory compaction.Though be unburned, it is the cost height not only, and surface irregularity, degree of compactness is poor, and influence is used.
Existing multiple be the Industrial Residue Brick of raw material with cinder or slag, be raw material as coal gangue, slag, cement clinker, clay and the boiler slag of Chinese patent application 02100218.5 " non-calcine hollow brick " after with unslaked lime, burning; " 01102954.4 the processing method of a kind of non-autoclaved and unburned quick production fly ash building block or flyash brick " etc.
China renovates in the city on a large scale at present, and building waste residue has become new environomental pollution source.If can turn waste into wealth, be that main raw material is produced material of construction with the building waste residue, will be extremely meaningful to the protection environment.Chinese patent application 87108093.1 " manufacture method of cinder brick for construction " is a main raw material with the building waste, but still needs autoclave curing behind its green brick forming, and power consumption is big, and cost height, and making equipment complexity are so be difficult to popularize.
(3) summary of the invention
The purpose of this invention is to provide a kind of with the construction waste be main raw material unburned Industrial Residue Brick with and preparation method thereof.
Unburned Industrial Residue Brick provided by the invention is made by the following raw material with weight proportion: building waste residue 36~43%, rock 44~51% inferior, cement 5~10%, flyash 3~6%, lime 3~6%, the water reducer of its weight 1~2% of adding in the cement.
Its better scheme is: (by weight) building waste residue 38.5~39.5%, rock 46.5~47.5% inferior, cement 5.5~6.5%, flyash 3.5~4.5%, lime 3.5~4.5%.
The making method of unburned Industrial Residue Brick provided by the invention, operation comprises: at first get the raw materials ready by the said ratio amount, carry out material sorting, fragmentation then, mill, sieve, batching, add water and fully mix, moulding, maintenance, its building waste residue, rock inferior are broken respectively, milling is the powder of granularity less than 6 millimeters, add the water that is equivalent to above-mentioned compound weight 3~8%, mix, send into afterwards in the mould, compression moulding under the pressure of 170~200 kg/cm, adobe was placed maintenance more than 15 days under the temperature more than 0 ℃.
The advantage of the unburned Industrial Residue Brick of the present invention is: 1, utilize building waste residue to be main raw material, promptly solved the handling problem of a large amount of building wastes, saved the raw materials cost of brick again; 2, this prescription material interacts and reacts, and is that solidifiable reaches the hardness requirement in the normal temperature maintenance, and energy-saving effect is obvious; 3, after this prescription mixing of materials stirred, hydrability was good, solidifies quickening, has guaranteed the intensity of adobe, the yield rate height; 4, the internal radiation index (Ira) according to this brick of survey report of Product Quality Supervision ﹠ Testing Office is 0.02, and external radiation exposure index (I γ) is 0.1, all is significantly smaller than construction main body material technical requirements 1.0; Ultimate compression strength mean value (f) is 20.5MPa, strength standard value (f k) be 18.0Mpa, all above construction main body material MU15 level technical indicator, ultimate compression strength mean value (f) 15.0MPa, strength standard value (f k) 10.0Mpa; 5, this product degree of compactness height, insulation, sound insulation, fire prevention etc. are functional.
The advantage of the making method of the unburned Industrial Residue Brick of the present invention is: 1, only need maintenance at normal temperatures after this formed product, need not to fire or vapor cure, energy consumption reduces greatly, and manufacture craft equipment is also simplified greatly, thereby product cost significantly descends; 2, green brick forming under pressure, faster than general vibratory compaction mode of production moulding caking, easily demoulding is easily realized streamline production; 3, the pressure forming green strength is bigger, the yield rate height, and directly piling is stacked, and has reduced the stacking place.
