Abstract
The invention discloses common concrete containing smelting waste sand, and the common concrete comprises 1,100-500kg of cement, 50-160kg of coal ash, 1,000-1,150kg of gravel, 660-790kg of manufactured sand, 150-170kg of water and 5.3-11kg of water reducing agent all by weight percentage. Compared with the existing commonly used concrete, the concrete disclosed by the invention is added with the manufactured sand; the manufactured sand is the smelting waste sand formed by processing the smelting waste generated in industrial production, the sand ratio of the manufactured sand can reach 35-45%, and the resource can be fully used; as a substitute of natural sand, the manufactured sand can be used for reducing the environmental damage caused by overexploitation of natural sand, and further lowering the cost; moreover, the working performance of the manufactured sand used in concrete is not changed in comparison with the natural sand.
Description
Technical field
The present invention relates to a kind of material of construction, especially use a kind of normal concrete that contains melting waste slag sand of the melting waste slag formation after processing produced in industrial production.
Background technology
Concrete is generally made gelling material with cement, sand, masonry gather materials, with water (adding or do not add admixture and adulterant), coordinate by a certain percentage, through stirring, moulding, maintenance and obtain, its use range is very extensive, not only in various civil engineering works, using, is exactly exploitation, geothermal engineering of shipbuilding, mechanical industry, ocean etc., and concrete is also important material.Development along with economy, scientific and technological level, the urban construction of China is also day by day burning hot, wherein need to use a large amount of concrete, and existing most of concrete is natural sand, stone in preparation used gathering materials in period mostly, but sand, stone resource as natural aggregate are day by day deficient, price increase, and excessively gather sandstone and also environment has been caused to certain destruction.On the other hand, industrial residue is as the harmful solid waste given off in industrial production, and its long-term accumulation not only takies a large amount of soils, and can cause severe contamination and harm to water system and atmosphere.The result that the mass breaking barren rock is piled up, damaged large stretch of farmland and backwoods, and it is very necessary therefore it being carried out to recycling.More existing cement mill only are confined to the cement spike as cement brick to the application of industrial residue, and usage quantity only accounts for 20%～30%, and the ratio of its use is not high, does not reach the effect to the comprehensive utilization of resource.
Summary of the invention
The objective of the invention is: for above-mentioned deficiency, provide a kind of normal concrete that contains melting waste slag sand, its production cost is low, can utilize resources synthetically.
For achieving the above object, the technical solution used in the present invention is:
A kind of normal concrete that contains melting waste slag sand, comprise cement, flyash, rubble, artificial sand, water and water reducer, described cement is between 1100～500kg, described flyash is between 50～160kg, described rubble is between 1000～1150kg, and described artificial sand is between 660～790kg, and described water is between 150～170kg, described water reducer is between 5.3～11kg, and above each integral part all by weight percentage;
Described artificial sand is the melting waste slag sand that the melting waste slag that produces in industrial production forms after processing, the chemical composition of described melting waste slag sand comprises silicon-dioxide (SiO), ferric oxide (Fe O), aluminum oxide (Al O), calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K O), (Na O) received in oxidation, sulfur oxide (SO), wherein silicon-dioxide (SiO) content is between 45%～55%, ferric oxide (Fe O) content is between 4.5%～4.8%, aluminum oxide (Al O) content is between 4%～4.5%, calcium oxide (CaO) content is between 7%～7.5%, magnesium oxide (MgO) content is between 26%～30%, potassium oxide (K O) content is between 0.15%～0.22%, it is between 0.18%～0.23% that (Na O) content is received in oxidation, sulfur oxide (SO) content is between 0.08%～0.1%.
Further, described artificial sand fineness is 2.3～3.0.
Beneficial effect of the present invention: compare with existing concrete commonly used, added artificial sand in proportioning of the present invention, this artificial sand is the melting waste slag sand formed after processing by the melting waste slag produced in industrial production, and the shared sand coarse aggregate ratio of artificial sand can reach between 35%～45%, to resource, can utilize fully, substitute as natural sand, the use of artificial sand can not only reduce the environmental disruption caused because of overexploitation natural sand, its cost also can further reduce, and the use of artificial sand in concrete compare its serviceability with natural sand constant.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
A kind of normal concrete that contains melting waste slag sand of the present invention, comprise cement, flyash, rubble, artificial sand, water and water reducer, described artificial sand is the melting waste slag sand that the melting waste slag that produces in industrial production forms after processing, the chemical composition of described melting waste slag sand comprises that silicon-dioxide (SiO), ferric oxide (Fe O), aluminum oxide (Al O), calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K O), oxidation receive (Na O), sulfur oxide (SO), further, described artificial sand fineness is 2.8.Further, the particle diameter of described artificial sand has respectively three kinds: 0～5mm, 5～16mm, 16～31.5mm.During concrete in preparation in the present invention, wherein cement used can be between 1100～500kg, described flyash is between 50～160kg, described rubble is between 1000～1150kg, described artificial sand is between 660～790kg, described water is between 150～170kg, and described water reducer is between 5.3～11kg, and above each integral part all by weight percentage; And each chemical composition of artificial sand, wherein silicon-dioxide (SiO) content is between 50%～55%, ferric oxide (Fe O) content is between 4.5%～4.8%, aluminum oxide (Al O) content is between 4%～4.5%, calcium oxide (CaO) content is between 7%～7.5%, magnesium oxide (MgO) content is between 28%～31%, potassium oxide (K O) content is between 0.15%～0.22%, it is between 0.18%～0.23% that (Na O) content is received in oxidation, and sulfur oxide (SO) content is between 0.08%～0.1%.
