Abstract
The invention discloses a baked brick prepared by sintering crushed construction waste, mud cakes by pressing waste mud, desulphurization gypsum and coal cinder in a leather factory as aggregates and admixture with a certain ratio. Compared with common baked bricks, the invention reduces the production cost while meeting the compressive strength. In the solid waste brick formula, all raw materials are selected from construction and industrial wastes, so that the invention solves the difficult problem of processing construction waste mud and construction waste and the problem of environment pollution caused by the desulphurization gypsum and other solid wastes, protects cultivated land resources, and realizes the recycling of the solid wastes.
Description
Technical field
The present invention relates to a kind of solid waste baked brick making method, be specifically related to a kind of mud cake, building waste, tannery's cinder making formula of sintered brick that is applicable to after desulfurated plaster, waste mud squeeze, belong to civil construction material technology field.
Background technology
There is a large amount of SO every day in general coal-burning power plant manufacturing enterprise
2Be discharged in the atmosphere by the flue gas flue, caused the serious environmental pollution.Bring a series of Litter governing problem to enterprise, obtain so-called desulfurated plaster by discharged flue gas being carried out the desulfurization processing.At present still do not have the report that carries out vitrified brick by desulfurated plaster, though the report of ardealite baked brick is arranged, yet in the sintering process that is adopted still with clay as main raw material(s).Utilizing clay to carry out vitrified brick will cut the earth and ruin the field, the land resources of consume valuable, the havoc eubiosis.For many years, the order of forbidding producing and using solid clay brick in national part city is repeatedly assigned about ministries and commissions by country.Therefore, the alternative brick producing material of searching clay has great importance.
The a large amount of waste muds that produce in the geotechnical engineering construction mainly are made up of clay, sewage, drilling cuttings and mud conditioner etc.The discharging of the unrest of waste mud has in the past caused the pollution of a large amount of urban rivers, river course silting.In recent years, by the stringent regulations of various places government department, this situation is alleviated to some extent, has also promoted the development of mud Technology in Pressing, yet is subjected to the influence of transportation cost, and the treatment of mud cost can be in any more always, has caused the tremendous economic burden to construction enterprises.At present, the main method of disposal of the mud squeezing formed mud cake in back has: the one, fertilize the soil nearby; The 2nd, outward transport backfill low-lying field; The 3rd, brickmaking.From the angle analysis of industrial chain, utilize the mud cake brickmaking after mud squeezes both can solve problem of environmental pollution that mud causes, reduce transportation cost, can solve brickmaking enterprise again and produce and the contradiction of protecting farmland, be effective measure of achieving many things at one stroke.
On the other hand, along with the China's economic fast development, the construction project in city, rural area is increasing, stays a large amount of building wastes in these project constructions.The landfill disposal of building waste has taken a large amount of soils and fund.Therefore, carry out the comprehensive utilization of resources of building waste, have great economical, societal benefits.
Adopt the desulfurated plaster vitrified brick generally need adopt interior fuel, the effect of bringing on producing is to reduce fuel consumption, shortens roasting time, and shortcoming is if interior fuel volume is excessive, can cause the fragment of brick core many, and the space is big, and ultimate compression strength reduces.The optimum incorporation of interior fuel is relevant with the type of vitrified brick composition and interior fuel, need be optimized design.
Building waste, mud cake mud squeezing after and the flyash of the present invention with desulfurated plaster, after pulverizing adds a certain proportion of admixture and carries out sintering as aggregate, has obtained a kind of novel solid waste baked brick.Compare with the unselected clay vitrified brick, in the requirement of satisfying ultimate compression strength simultaneously, reduced production cost.This solid waste brick prescription; all raw materials all derive from building and industrial waste, have solved the processing difficult problem of building waste mud and building waste, have solved desulfurized gypsum and other solid problem of environmental pollution that waste causes; protect cultivated land resource, realized the recycle of solid waste.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can be applied to the high-performance of actual production, cheap solid waste baked brick prescription.This formula of sintered brick is a raw material with solid waste such as desulfurated plaster, waste mud, building waste, flyash, solves problem of environmental pollution that solid waste causes, and has protected cultivated land resource, has realized the recycle of solid waste.
Formula of sintered brick of the present invention, wherein the building waste mass ratio is 14.15%, mud cake quality is than 56.60%, desulfurated plaster mass ratio 14.15%, flyash mass ratio 9.43%, toughener mass ratio 5.66%.
Formula of sintered brick of the present invention, the mud cake that is adopted are mainly derived from the waste mud that bored pile construction produces, and mainly are made up of compositions such as clay, sand, stones, and its medium clay soil composition accounts for more than 70% of solid composition.
Formula of sintered brick of the present invention, the mud cake that is adopted is mainly derived from the mud that produces in the bored pile construction, wherein mud adopts the moulding of flocculation combine milling process, removes macrobead compositions such as shakeout, stone before the squeezing earlier, and the mud cake water content after the squeezing is controlled at 35%.
Formula of sintered brick of the present invention, the building waste that is adopted mainly are made up of waste concrete, brickbat slag, mortar, and wherein the content of brickbat slag accounts for 20% of building waste.
Formula of sintered brick of the present invention, the building waste that is adopted is the diameter of milling through the ball mill powder less than 2mm.
Formula of sintered brick of the present invention, the desulfurated plaster major ingredient that is adopted is a terra alba, content is more than 75%.
Formula of sintered brick of the present invention is characterized in that: the flyash that is adopted is the power station dry discharge fly ash, SiO
2, the mass fraction of CaO is respectively 65.2,4.0%
Formula of sintered brick of the present invention, the admixture that is adopted are toughener, and major ingredient is Fe
