Abstract
The invention discloses an antimony tailing aerated concrete block and a preparation method thereof. The antimony tailing aerated concrete block comprises the following raw material parts by weight: 60-80 parts of antimony tailings, 10-25 parts of cement, 10-30 parts of lime, 0.05-0.15 part of foaming agent, and water, wherein the weight of the water is 15-40% of the total weight of the dry materials. During preparation, the materials are added in the following sequence: the antimony tailings, the water, the cement and the lime, and the foaming agent; and the materials are mixed uniformly, stand still to be subjected to pre-curing for 2-3 h, is turned and cut, and is subjected to autoclaving curing for 10-12 h, so as to form the finished product. According to the invention, a great quantity of tailings produced in an antimony ore separation process are adopted as the main raw material to prepare the building concrete block with the high strength above 5 MPa, so as to achieve the following effects: new economic benefits are created for enterprises, and the cost for treating the tailings is reduced; the cyclic utilization of the tailings is facilitated to reduce the environmental and ecological pollution caused by the tailings; and the occupancy of land resource is avoided.
Description
Technical field
The present invention relates to the build concrete building block, particularly a kind of antimony mine tailings air-entrained concrete building block and preparation method thereof.
Background technology
The antimony mine tailings that the classified processing of mine tailing that produces in the antimony ore ore dressing produces afterwards are usually as waste disposal, but these slags are pulverous, be difficult for condensing, usually need just can condense slowly more than 20 days, therefore before the waste residue of powdery did not condense, the waste residue of stacking was met wind and is easy to produce airborne dust, serious environment pollution, can destroy ecotope and the eubiosis, have very strong contaminative, can not at will topple over.Therefore common way is to stack after waste residue is processed again, and needs special stockyard to stack and stack these waste residues, also needs trucking costs and the expense of setting up the stockyard, has increased the cost of business processes waste residue, and the land occupation resource.
Summary of the invention
The object of the invention is to: a kind of antimony mine tailings air-entrained concrete building block and preparation method thereof is provided.It is main raw material that the method adopts the mine tailings that produce in the antimony ore ore dressing process, makes high-intensity build concrete building block, and its making method is easy to grasp, prescription rationally, and is with short production cycle, reduces industrial waste to the pollution of environment, economize the land resource, be conducive to the recycling of waste material.
Technical scheme of the present invention: a kind of antimony mine tailings air-entrained concrete building block is characterized in that: it is the raw material with the following weight proportioning, and 15～40% the water that adds again the siccative gross weight is made;
60～80 parts of antimony mine tailings, 10～25 parts of cement
10～30 parts in lime, 0.05～0.15 part of foaming agent
The preparation method of described antimony mine tailings air-entrained concrete building block is:
A, first the antimony mine tailings are added the water mixing, add again cement and lime mixing, add at last the foaming agent mixing and make slurry, get the A product;
B, pour the A product in mould casting, through quiet stop precuring 2～3 hours, upset cutting, steam press maintenance 10～12 hours finished product.
Described antimony mine tailings are antimony ore rejects that particle diameter is no more than 0.2mm.
Described lime be particle diameter be no more than 0.05mm can generate calcium hydroxide unslaked lime.
Described cement is ordinary Portland cement, slag cement.
Described foaming agent refers to aluminium powder or aluminium powder cream.
Compared with prior art, the invention provides a kind of antimony mine tailings air-entrained concrete building block and preparation method thereof.A large amount of mine tailings that the present invention produces in the antimony ore ore dressing process add suitably batching, and adopt suitable preparation method as main raw material, make the build concrete building block, have both alleviated the pollution of industrial residue to environment, have increased novel material for construction work again.The present invention fills a prescription rationally, making method rationally and be easy to grasp, the block strength of making very high (can reach more than the 5MPa) reaches the standard of national build concrete building block.Have be easy to produce, with short production cycle, production cost is low, the characteristics of good product effect.
