Abstract
The invention provides an iron tailing concrete which comprises the following ingredients of cement, mineral processing barren rocks and detritus, admixture, water and pumping aid for the concrete determined according to performances, and the ingredients of the concrete according to the weight percentages of the concrete are respectively 4-20 percent of cement, 0-35 percent of mineral processing barren rocks and detritus, 1-8 percent of admixture, 1.5-2.5 percent of pumping aid for the concrete based on the weight sum of the cement and the admixture, and the balance of water. The invention hasthe effects that the novel concrete adopts tailing ores and detritus and is applied to the production of the concrete for partially or completely replacing natural aggregate. The concrete can reducethe pollution to the environment from mineral processing barren rocks, decrease the production volume and the production energy consumption of natural ore materials, accord with three 'green' meaningssuggested by the world environment organization: saving resources and energy; no environmental damages, and more environment friendly; and also according with the strategy of sustainable development,thereby not only satisfying requirements of the contemporary people, but also not damaging the capacity of satisfying unborn requirements.
Description
Technical field
The present invention relates to a kind of concrete, particularly adopt processing barren rocks to pass through cleaning, fragmentation, screening back, partly or entirely replace a kind of iron tailing concrete of natural aggregate as aggregate.
Background technology
Present normal concrete gathers materials and is mainly natural sandstone, is Nonrenewable resources, and machine instruction statement mining had both destroyed physical environment, caused the pollution of environment again.And processing barren rocks and chip, total iron (TFe) grade is lower, does not have comprehensive recovery value.Because the quickening of China's capital construction, construction industry enters the high speed development stage, the concrete market requirement is increasing, cause the exploitation of natural sand stone ore also sharply to increase, and the stacking of Steel Plant's processing barren rocks and chip has caused the pollution and the potential safety hazard of environment too, the treatment capacity and the processing costs of processing barren rocks and chip are more and more higher, and the social concern that causes thus is also more and more.
At present, the treating method of processing barren rocks and chip mainly is to throw aside or landfill, this not only land occupation but also contaminate environment.And, mix the back according to a certain percentage with grating, and utilize this new concrete that partly or entirely replaces natural aggregate to prepare to be the exploitation direction as new concrete aggregate with after the fragmentation of processing barren rocks process, cleaning and the classification.Processing barren rocks and chip technology can realize the utilization to the discarded ore of flood tide, thereby limited resources is utilized again, have solved environmental problem again.This is the development green concrete, realizes one of main path of building products ecology.
Summary of the invention
For solving the problem that exists in the above-mentioned architectural environment, the invention provides a kind of iron tailing concrete, be beneficial to reduce the pollution of processing barren rocks, reduce natural sand exploitation of stone amount and exploitation energy consumption environment, reduce production costs, satisfy the needs of construction market concrete product and performance thereof.
For realizing goal of the invention, the technical solution used in the present invention provides a kind of iron tailing concrete, the concrete pumping agent that the composition of this iron tailing concrete has cement, processing barren rocks and chip, adulterant, water and determines according to performance, by the described composition of weight concrete % is respectively cement 4-20%, processing barren rocks and chip 0-35%, adulterant 1-8%, the concrete pumping agent is 1.5～2.5% of cement and an adulterant sum weight, and all the other are water.
Described processing barren rocks and chip account for the 30%-40% of new concrete gross weight.
Described adulterant refers to flyash and GBFS.
The granularity of described processing barren rocks and chip is: the processing barren rocks particle diameter is 5-25mm, and the fineness modulus of chip is 1.9-3.2.
The described concrete pumping agent of determining according to performance is commercially available concrete pumping agent.
Effect of the present invention is to adopt mine tailing stone and chip, partly or entirely replaces natural aggregate and is applied to concrete production.This concrete can reduce the pollution of processing barren rocks to environment, reduces natural sand exploitation of stone amount and exploitation energy consumption, and meet the three big implications of " green " of World Environment Organization's proposition: (1) economizes on resources, the energy; (2) do not destroy environment, more should help environment; (3) Sustainable development both can have been satisfied the demand of contemporary people, did not endanger the ability that future generations satisfy the demand again.
Embodiment
In conjunction with the embodiments a kind of iron tailing concrete implementation procedure of the present invention is illustrated.
Iron tailing concrete of the present invention is gathered materials by cement, thickness, i.e. processing barren rocks and chip, adulterant, water and the admixture composition definite according to performance.The breakthrough point is to adopt processing barren rocks and chip partly or entirely to substitute natural rock; with supposition mass method design mixture proportion; again concrete is carried out the adjustment of aspects such as unit weight, workability according to the trial mix result; processing barren rocks and chip account for the 30%-40% of concrete gross weight in the designed proportioning, meet renewable resource management method and utilization of the recycling of renewable resources and waste treatment and dispose management regulation and state environment protecting standard compulsive clause.
The concrete pumping agent that the composition of iron tailing concrete of the present invention has cement, processing barren rocks and chip, adulterant, water and determines according to performance, by the described composition of weight concrete % is respectively cement 4-20%, processing barren rocks and chip 0-35%, adulterant 1-8%, the concrete pumping agent is 1.5～2.5% of cement and an adulterant sum weight, and all the other are water.
Described processing barren rocks and chip account for the 30%-40% of new concrete gross weight; The granularity of described processing barren rocks and chip is: the processing barren rocks particle diameter is 5-25mm, and the fineness modulus of chip is 1.9-3.2.Described adulterant refers to flyash and GBFS.
The particular case of iron tailing concrete of the present invention is as follows:
This iron tailing concrete is by cement, thickness gather materials (processing barren rocks and chip), adulterant, water and what determine according to performance is that commercially available naphthalene is that pumping agent is formed.Through test, this new concrete meets the cement concrete performance index request of the C10-C60 strength grade of demand, and concrete workability is good, and the slump, divergence etc. satisfies construction requirement.Through the total institute of Beijing mining and metallurgy and quality monitoring testing station the 21 station, Tianjin according to JC/T1060-2007 " residue doping quantity measuring method in the silicate building material made " detect (report number: J90320W4) this new concrete meet the specifications requirement, satisfy the engineering construction performance.
This iron tailing concrete, (1) steel mill's processing barren rocks and chip; (2) proportioning aspect with rational proportion, partly or entirely replaces natural rock according to test.
Through the repetition test of a large amount of starting material, concrete mix, planning has designed the series of concrete proportioning that can satisfy the construction market demand, and is as follows:
