The attapulgite pyroclastic rock concrete aggregate is taken as construction materials, low in processing cost and has good social and economical benefits, the needed technical equipment is simple; the most of ingredients of the attapulgite pyroclastic rock concrete aggregate adopt various wastes, so that not only can the resource utilization ratio be improved, the wastes are turned into wealth, but also the occupied space is reduced, the environment is protected and purified, the energy resources are saved, the economical benefits are improved, and the attapulgite pyroclastic rock concrete aggregate is suitable for the common concrete engineering.
Description
Technical field
The present invention relates to material of construction, be specifically related to the ripe aggregate of a kind of Attapulgite volcanoclastic rock concrete.
Background technology
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, makes Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area are caused to serious threat.
Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
With the volcanoclastic rock that also has of attapulgite clay ore deposit symbiosis, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area
'sthickness is up to tens of rice, at attapulgite clay in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, according to field trip, and 1 ton of attapulgite clay of every exploitation, the volcanoclastic rock producing has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock of generation, up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, causes the serious wasting of resources and financial loss.
Building waste refers to the waste that construction, unit in charge of construction or individual build, lay or remove, produce in repairerment process all kinds of buildingss, structures, pipe network etc.The composition of building waste has: the tr of the yellow ground being scattered in the mortar being scattered and concrete, brickbat and broken concrete, handling process, stone, piece stone, dregs, steel scrap muscle, waste iron wire, various steel scrap accessory, metal pipe line waste material, useless bamboo wood, wood chip, wood shavings, various finishing material and packing bag etc.
Coal gangue is thrown aside, takies tract, and sulfide in coal gangue is overflowed or leached can atmosphere pollution, farmland and water body, and waste dump also can spontaneous combustion presence of fire, or in avalanche in rainy season, silts river up and cause disaster.
Summary of the invention
The object of the invention is to overcome weak point in prior art, provide a kind of Attapulgite volcanoclastic rock concrete ripe aggregate.
The ripe aggregate of Attapulgite volcanoclastic rock concrete is comprised of attapulgite clay mine tailing, volcanoclastic rock mixture, building waste, opal, coal gangue and montmorillonite mine tailing.
The production method of the ripe aggregate of Attapulgite volcanoclastic rock concrete: the finished product that the batching of the ripe aggregate of Attapulgite volcanoclastic rock concrete is stirred and pulverize, soak, be packaged as the ripe aggregate of Attapulgite volcanoclastic rock concrete after extruding, roasting, pulverizing and screening.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, as a kind of mine tailing, abandons, and causes a large amount of wastings of resources.
Volcanoclastic rock is the rock of the transitional type between magma lava and sedimentogeneous rock, the material that wherein more than 50% composition is sprayed by pyroclastic flow forms, and these tephras are mainly the lava of premature coagulation on volcano, the rock formation that passage is around burst when volcanic eruption.Volcanoclastic rock mixture comprises landwaste, brilliant bits, glassiness bits, slurry bits, volcanic block (diameter is greater than 100 millimeters), volcanic gravel (diameter is greater than 2 millimeters) and volcanic ash (diameter is less than 2 millimeters), volcanoclastic rock main chemical compositions is silicon-dioxide and aluminum oxide, can increase the intensity of the ripe aggregate of Attapulgite volcanoclastic rock concrete.
Select the yellow ground, stone and the dregs the like waste that in the mortar that is scattered in construction work, concrete, brickbat, broken concrete, handling process, are scattered.
Opal and attapulgite clay symbiosis, be a kind of hard rock that attapulgite clay be difficult to be rejected in recovery process, as a kind of waste bulk deposition in attapulgite clay mining area.
The montmorillonite mine tailing that the present invention selects is distributed in the lower floor in attapulgite clay ore deposit mostly, be difficult to carry out independent exploitation, but montmorillonite mine tailing quality is harder, is applicable to producing aggregate.
Coal gangue is the solid waste discharging in coal mining process and coal washing process, has lower heating value, carbon containing 20～30%, and the present invention uses coal gangue can save part coal, increases the content of aluminum oxide, improves the intensity of the ripe aggregate of Attapulgite volcanoclastic rock concrete.
The present invention is achieved by following technical proposals:
1, the batching of the ripe aggregate of Attapulgite volcanoclastic rock concrete is comprised of following component by weight percentage: attapulgite clay mine tailing 5～25%, volcanoclastic rock mixture 10～35%, building waste 10～30%, opal 5～25%, coal gangue 2～15% and montmorillonite mine tailing 2～15%;
The production method of the ripe aggregate of described Attapulgite volcanoclastic rock concrete: (1) the batching of the ripe aggregate of Attapulgite volcanoclastic rock concrete is added in the two shaft pugmill mixer having moved and stirred, after stirring, inputting pulverizing in pulverizer is the mixture of the ripe aggregate of Attapulgite volcanoclastic rock concrete, particle fineness≤1.05 millimeter of the ripe aggregate mixture of Attapulgite volcanoclastic rock concrete; (2) will in the ripe aggregate mixture input of Attapulgite volcanoclastic rock concrete fermentation vat, soak, soak time is controlled at 24～72 hours; (3) by extruding in the ripe aggregate mixture input of the Attapulgite volcanoclastic rock concrete after soaking pair roller extrusion machine, be flap, thickness≤6.0 millimeter of flap; (4) by the ripe aggregate flap input of Attapulgite volcanoclastic rock concrete rotary type roasting roasting in kilns, maturing temperature is controlled at 650～950 ℃; (5) the ripe aggregate flap of cooled Attapulgite volcanoclastic rock concrete is pulverized and screening, it is 3.1～3.7 millimeters that the particle fineness of coarse aggregate is controlled, it is 2.3～3.0 millimeters that the particle fineness of middle aggregate is controlled, it is 1.6～2.2 millimeters that the particle fineness of fine aggregate is controlled, and is packaged as respectively the finished product of the ripe aggregate of Attapulgite volcanoclastic rock concrete;
