Abstract
The invention belongs to the metallurgy environmental protection technical field, in particular to a slag composite powder non-fired and non-steamed brick. The slag composite powder non-fired and non-steamed brick is characterized by comprising the following components by weight percent: 70 to 80 percent of slag, 18 to 25 percent of blast furnace slag micro powder and 0 to 10 percent of peastone. The manufacture method is that the slag, the blast furnace slag micro mist and the peastone are weighed according to the proportion, water is added, the water cement ratio is 0.22 to 0.29, and the raw material is stirred evenly in a blender, pressed, molded, stacked and maintained for 7 to 28 days. The slag composite powder non-fired and non-steamed brick has the advantages of simple preparation technology, low cost, high intensity and good quality. Technical indexes reach the national building brick standard.
Description
Technical field
The invention belongs to the metallurgical environmental protection technical field, be specifically related to a kind of slag composite powder non-fired and non-steamed brick.
Background technology
A kind of industrial residue that slag produces when being iron and steel enterprise's steel-making, its quantity is generally 10～20% of crude steel output, and generation is huge.The generation of national slag in 2006 is about 0.7 hundred million tons, and the Multipurpose Utilization of Steel Slag rate has only 20% according to incompletely statistics.Shortcomings such as traditional process for treating steel slag ubiquity floor space is big, the processing procedure environment pollution is serious, devices consume is big; Simultaneously general modified method owing to active oxidation calcium content height, instability in the slag, can't be promoted the use of usually normally.Storing up in a large number of slag brought a large amount of dust pollutions for the on-site environment of iron and steel enterprise, also taken valuable land resources, " the dual waste " of this resource of being known as in environmentology simultaneously in a large number.
Summary of the invention
Technical problem to be solved by this invention provides a kind of slag composite powder non-fired and non-steamed brick and manufacture method thereof.The preparation technology of this slag composite powder non-fired and non-steamed brick is simple, and cost is low, and what obtain two exempts from brick (free of calcining and steam curing) intensity height, good product quality, and every technical indicator all can reach national building brick standard.
For solving the technical problem that the present invention proposes, the technical scheme that is adopted is: a kind of slag composite powder non-fired and non-steamed brick is characterized in that it consists of by weight percentage: slag 70～80%, blast-furnace cinder micro-powder 18～25%, Guamishi 0～10%.
Press such scheme, described slag is through fragmentation, magnetic separation, and particle diameter is no more than the slag of 5mm.
Press such scheme, described blast-furnace cinder micro-powder is that blast-furnace cinder forms through levigate, and its reference area is not less than 450m
2/ kg.
Press such scheme, the two manufacture methods of brick of exempting from of described blast-furnace cinder slag composite powder, it is characterized in that may further comprise the steps: raw material slag, blast-furnace cinder micro-powder and Guamishi are taken by weighing by proportioning, add entry, wherein water/binder ratio is 0.22～0.29, stirs in mixer, and it is molded to shake then, piled bricks after the moulding, maintenance 7～28 days are promptly.
The present invention is directed to slag and can not be used for the technical bottleneck that building materials are produced without ageing, stabilization processes, adopt blast-furnace cinder-slag complex technique to produce two bricks of exempting from, not only can effectively solve iron and steel enterprise's invar slag and store up occupation of land and the secondary pollution problem of bringing in a large number, the bad problem of soundness is to kill two birds with one stone in the time of simultaneously can solving slag and make the building materials admixture.The inventive method can improve the processing and the disposal efficiency of steel enterprise waste residue, improves the exploitation level of secondary resource, also can reduce the use amount of building material industry cement simultaneously, for national energy-saving and emission-reduction contribute.
Beneficial effect of the present invention:
1. the two manufacture methods of exempting from brick of this blast-furnace cinder slag composite powder make full use of slag and the blast-furnace cinder that iron and steel enterprise produces, need not to add in addition materials such as lime, carbide slag, cementing agent, early strength admixture and cement, cost is low: free of calcining and steam curing, and do not need to be provided with fog room, the stacking maintenance gets final product, technology is easy, and is energy-conservation;
2. produce the two brick intensity height (compressive strength can reach more than the 26Mpa in 28 days) of exempting from of the blast-furnace cinder slag composite powder that obtains, good product quality, the surface crack-free, abrasion resistance is good, and its every technical indicator such as compressive strength, water absorption rate, weather resistance ability etc. reach national building brick standard.
The specific embodiment

1. material preprocessing: 1. get iron and steel enterprise's blast-furnace cinder, levigate, make its specific area be not less than 450m
2/ kg puts into 85 ℃ of oven dry of baking oven 2 hours, promptly gets blast-furnace cinder micro-powder, and is standby; 2. get iron and steel enterprise's slag, after fragmentation, magnetic separation, standby; 3. market acquisition finished product Guamishi is after mud is removed in washing, standby.
2. brickmaking: the content according to raw material among each embodiment among Fig. 1 takes by weighing the above-mentioned blast-furnace cinder micro-powder 20kg that handled through preprocessing, and slag 80kg adds entry, and wherein water/binder ratio is 0.22, and pour into then to mix in the mixer and stir, after mixing, discharging; Send into mould by belt transmission, the demoulding after hydraulic press vibratory compaction then, batch production, piling is stacked maintenance again, between curing time, fetches water 2 times the maintenance use of can dispatching from the factory after 28 days every day at interval.
Embodiment 2-5
Adopt the raw material after the material pre-process method is handled among the embodiment 1, according to the corresponding raw material proportioning of each embodiment in the table 1, water/binder ratio and curing time are according to the two bricks of exempting from of the method slakin slag composite powder of embodiment 1.
Table 1
The slag composite powder non-fired and non-steamed brick that embodiment 1-5 is prepared carries out performance test, the results are shown in table 2.
Can be got by table 2: the slag composite powder non-fired and non-steamed brick that present embodiment 1-5 produces is solid durable, good product quality, and its every technical indicator all can reach national building brick standard.
Table 2
