Abstract
Provided is a kind of concrete containing smelting waste slag coarse aggregates. The concrete comprises cement, smelting waste slag coarse aggregates, coal ash, sands, water and addition agents. There are two kinds of particle sizes of the smelting waste slag coarse aggregates, according to aggregate requirements and the particle sizes are 5-16mm and 16-31.5mm respectively. The smelting waste slag coarse aggregates are formed after processing of generated solid waste in industrial production. The prepared concrete has good workability. the intensity of the concrete produced from smelting waste slag coarse aggregates according to different ratios is higher than that of concrete produced from natural coarse aggregates by 2-3MPa. The concrete can meet extensive requirements, the smelting waste slags formed after processing of generated solid waste in industrial production are employed as substitutes of artificial sands, the working performances are unchanged, resource can be used fully, and the cost can be lowered further.
Description
Technical field
The present invention relates to a kind of material of construction, especially use a kind of concrete that contains melting waste slag coarse aggregate of the solid waste melting waste slag of formation after processing producing in industrial production.
Background technology
Concrete is generally made gelling material with cement, sand, masonry gather materials, coordinate by a certain percentage with water (adding or do not add admixture and adulterant), 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 giving off in industrial production, and its long-term accumulation not only takies a large amount of soils, and can cause the severe contamination of water system and atmosphere and harm.The result that mass breaking barren rock is piled up, has damaged large stretch of farmland and backwoods, and it is very necessary therefore it being carried out to recycling.More existing cement mill are only confined to the cement spike as cement brick to the application of industrial residue, and usage quantity only accounts for 20%～30%, and the sand coarse aggregate ratio of its use is not high, does not reach the effect to the comprehensive utilization of resource.
Summary of the invention
The object of the invention is: for above-mentioned deficiency, provide a kind of concrete that contains melting waste slag coarse aggregate, its production cost is low, can utilize resources synthetically.
For achieving the above object, the technical solution used in the present invention is:
A concrete that contains melting waste slag coarse aggregate, comprises cement, melting waste slag coarse aggregate, flyash, sand, water, admixture, and the particle diameter of described melting waste slag coarse aggregate is joined requirement according to collection respectively two kinds: 5～16mm, 16～31.5mm, the solid waste that described melting waste slag coarse aggregate produces in industrial production forms after processing, the chemical composition of described melting waste slag coarse aggregate comprises silicon-dioxide (SiO), ferric oxide (FeO), aluminum oxide (AlO), calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (KO), (NaO) received in oxidation, sulfur oxide (SO), wherein silicon-dioxide (SiO) content is between 50%～55%, ferric oxide (FeO) content is between 7%～7.5%, aluminum oxide (AlO) content is between 6%～6.8%, calcium oxide (CaO) content is between 7%～7.5%, magnesium oxide (MgO) content is between 20%～25%, potassium oxide (KO) content is between 0.5%～0.7%, it is between 0.40%～0.46% that (NaO) content is received in oxidation, sulfur oxide (SO) content is between 0.07%～0.09%.
Further; it is that two kinds of grating particles of 5～16mm, 16～31.5mm mix while using that described melting waste slag coarse aggregate is joined requirement particle diameter according to collection; described cement is 100～500kg; described 5～16mm melting waste slag coarse aggregate is between 200～700kg; described 16～31.5mm melting waste slag coarse aggregate is between 400～850kg; described flyash is 0～130kg; described sand is 600～800kg; described water is 150～170kg; described admixture is 5～14kg, and above each integral part all by weight percentage.
Further, according to concrete workability, require capable of regulating 5～16mm and two kinds of grating particle consumptions of 16～31.5mm.
Beneficial effect of the present invention: compare with existing conventional concrete, in proportioning of the present invention, used melting waste slag coarse aggregate, this melting waste slag coarse aggregate is that the solid waste producing in industrial production forms after processing, and replace natural rubble coarse aggregate substitution rate can reach 100%, to resource, can utilize fully, substitute as natural coarse aggregate, the use of melting waste slag coarse aggregate can not only reduce the environmental disruption causing because of the natural coarse aggregate of overexploitation, its cost also can further reduce, and the use of artificial sand in concrete compare its serviceability with natural sand constant.
