Abstract
A load-bearing building block or brick is prepared from iron ore tailings (20-40 Wt%), broken stone (40-60), powdered coal ash (10-30), Portland cement (9.9-20) and water-reducing agent (0.1-1). Its making technology without calcining and steaming is also disclosed.
Description
Technical field
The present invention relates to a kind of buring free, steaming free bearing building blocks or brick and manufacturing process thereof, particularly a kind of buring free, steaming free bearing building blocks or brick and manufacturing process thereof of utilizing prepared from tailing sand of iron ore to make belongs to the building brick technical field.
Background technology
In China's mining technical process, the processing of mill tailings and application are the difficult problems in the mining technology always, generally take at present mill tailings to fill out the extensive processing mode that ditch is stacked, this mode makes a large amount of mine tailing air storages cause surface vegetation to destroy on the one hand, cause the pollution of mine environment, cause soil erosion and desertification, the mine tailing resource does not obtain utilizing on the other hand, whole mine resources utilization ratio is low, causes the waste of national mine resources.Simultaneously; in the building brick technical field; country is the protection clay resource; prohibited the use clay brick; developing ecotecture becomes the research direction of clay brick substitute products with brick; the no-baked no-steamed building of having used at present mainly is fly ash in electric power plant, Steel Plant's blast-furnace slag with the raw material of building block, brick, is not the reported in literature of building block, brick and the manufacturing process thereof of main raw material with the iron ore mine also.
Summary of the invention
Purpose of the present invention overcomes the deficiencies in the prior art, provides that a kind of what have the ecological, environmental protective effect is building block, brick and the manufacturing process thereof of main raw material with the prepared from tailing sand of iron ore.
The object of the present invention is achieved like this:
Prepared from tailing sand of iron ore buring free, steaming free bearing building block of the present invention or brick, form by prepared from tailing sand of iron ore, rubble, flyash, silicate cement and cement water reducing agent, its weight percent is: prepared from tailing sand of iron ore: 20-40%, rubble: 40-60%, flyash 10-30%, silicate cement 9.9-20%, cement water reducing agent: 0.1-1%, the particle diameter of described prepared from tailing sand of iron ore is 0.3-2.0mm, and described ballast grain sizes is 5-20mm, and described flyash is I level, II level ash.
The manufacturing process of prepared from tailing sand of iron ore buring free, steaming free bearing building block of the present invention or brick comprises the following steps:
A. iron ore mine is sieved, utilize shaking-sieving technology, the screening particle diameter is at the coarse particles of the 0.3-2.0mm fine aggregate as building block or brick from mine tailing;
B. rubble is sieved, sieving out particle diameter from the barren rock that mining is peeled off is the coarse aggregate of the rubble of 5-20mm as building block or brick;
C. prepared from tailing sand of iron ore, rubble, flyash, silicate cement and cement water reducing agent are taken by weighing preparation by above-mentioned bearing building block for building or brick weight percent, the water that adds raw material gross weight 40-60%, after the mixing and stirring, mix machinery is sub-packed in building block or the bricks die, extrusion jolt moulded;
D. with stripping forming building block, brick piling, add a cover to 12-36 hour, add a cover straw mat again after opening straw mat and watering, watered once in every 6-10 hour, continue 5-9 days, throw off straw mat natural curing then to 22-28 days with straw mat.
Buring free, steaming free bearing building blocks of the present invention or brick, with the iron ore mine is raw material, form with addition of other raw material manufacturing, opened up the approach that utilizes again, solved mill tailings and filled out ditch and stack and to cause mine environment to pollute and the destructive problem for the mill tailings that produces in China's mining technology; After clay brick bans use of,, and, make the building block of novel no-baked no-steamed building, the brick that are applicable to Highrise buildings simultaneously by rational manufacturing process for building block, brick have found new low price raw material; The present invention is by the mine tailing resource reutilization, prevents that tailings pollution from preserving the ecological environment, and both met the objective law of recycling economy, meets the develop a mine industry policy of resource and development of new building brick of state guarantee mine environment again.
