Description
Technical field
The present invention relates to building material field, more particularly to a kind of iron tailings sand dry-mixed masonry mortar, is a kind of ecological ring
Guarantor's type construction material.
Background technology
Since reform and opening-up, China has turned into the construction market of maximum in the world, and sand using amount rises year by year, and long-term opens
Adopt, cause natural sand resource progressively exhausted, find new sand resource, reduction masonry mortar cost is very urgent, so necessary
It is suitable for sand material material to find.
China's iron ore disseminated grain size is thin, and iron tailings chemical composition is with the composition required for structure material very close to this is
Carry out research of the mine tailing for making construction material and create condition.Building sand or aggregate etc. are most basic construction materials,
Chemical composition is not strict with, only requires that material has certain hardness and granularity, and iron tailings quality meets building sand
Standard, quantity is more, without reprocessing, can make up the shortcomings that natural sand is with poor quality but high price.On the other hand, largely gone back using mine tailing
Can solve the problems such as tailings stack anxiety, environmental pollution.The mine tailing of iron ore is after rotational flow sorting, and fineness mould degree is 2.3~3.0
In the range of middle sand can directly substitute natural sand be used for masonry mortar in, the mine tailing after levigate screening largely belongs to
Ultra fine sand, fine sand scope, as building sand directly using at present it is relatively difficult, by this part iron tailings and natural sand or machine
Sand processed composition mixed sand substitutes natural sand fine aggregate to produce masonry mortar be feasible.
In recent years, country has implemented a series of preferential policies such as the deduction and exemption resource expenses of taxation, guiding and encouragement society and enterprise in succession
The exploitation project of the resources such as industry fund input mine tailing, and actively support enterprise to carry out research of technique, undergo technological transformation, add
The technological innovation of strong comprehensive utilization of tailing, research and development advanced technology, sophisticated equipment, advanced technologies, accelerates correlative study achievements conversion.
Had obvious social and economic benefits with mine tailing substitution natural sand, be the technology research project that country encourages, building will be turned into
The inexorable trend of industry development.There are many technologies in iron tailings application aspect, be largely for preparing steam pressure as construction material
Air-entrained concrete building block, foamed hollow brick, light wall material and roadbed filling etc..And iron tailings is substituted into natural sand and is used to build
Build mortar without pertinent literature report, Chinese patent 103011697A disclose it is a kind of using iron tailings powder substitute fine quartz sand make
External thermal insulation polymer mortar and its manufacture method, the iron tailings powder in this method are less than 0.6mm iron tailings powder from particle diameter
Substitute fine quartz sand and make external thermal insulation polymer mortar, have essential distinction with the present invention.
The content of the invention
The purpose of the present invention develops iron tailings, there is provided a kind of iron tailings sand is done aiming at the deficiencies in the prior art
Mixed masonry mortar, a kind of masonry mortar that partial natural sands are substituted using iron tailings, natural sand is substituted as carefully using iron tailings
Aggregate prepares masonry mortar.
The object of the present invention is achieved like this：A kind of iron tailings sand dry-mixed masonry mortar, it is characterised in that constituent
And folk prescription consumption proportion (kg/m3) as follows：
Fine aggregate, 1320~1550, described fine aggregate uses iron tailings sand or iron tailings mixed sand；
Binder materials, 160~365, described gel rubber material uses common portland cement or masonry cement；
Pozzolanic reaction admixture, 91~170, described admixture uses II level flyash；
Water-keeping thickening material, 17~32, described water-keeping thickening material is mainly by several organic matter surfactants
It is combined；
Additive, 3.7~8.1, described additive is a kind of compound high efficiency water reducing agent；
Water, 270~330；
Described masonry mortar strength grade is DM2.5~DM30.
As currently preferred technical scheme, described iron tailings sand or iron tailings mixed sand belong to sand in II areas, iron
Clod content≤1.0%, SO3≤0.5% in CHARACTERISTICS OF TAILINGS SAND, chloride≤0.02%.
As currently preferred technical scheme, described water-keeping thickening material be by sldium lauryl sulfate (SDS) 16%,
AESA (AESA) 45%, the organic matter surfactant of alkyl, polyether (PO-EO copolymers) 39%
Mixing composition.
As currently preferred technical scheme, described compound high efficiency water reducing agent be by polycarboxylic acids, citric acid and
Its salt and alkyl benzene sulfonate compounding form.
As currently preferred technical scheme, described cement uses 42.5 grades or 32.5 grades.
As currently preferred technical scheme, described iron tailings mixed sand is iron tailings and natural sand or Machine-made Sand
Mixture, iron tailings account for mixture ratio be 30%~70%.
Compared with prior art, it is an advantage of the invention that：Destruction of the exploitation natural sand to ecological environment is not only reduced, and
And reduce destruction of the iron ore mine to environment in itself, masonry mortar cost is substantially reduced, is reached using waste mining rock, milltailings
To 30%, enterprise, which can also enjoy, exempts from value-added tax policy.
Brief description of the drawings
Embodiment
To further describe the present invention, with reference to embodiment, the invention will be further described.
Embodiment 1：
After rotational flow sorting, middle sand of the fineness mould degree in the range of 2.3~3.0 can be substituted directly naturally the mine tailing of iron ore
Sand is used in masonry mortar, and the mine tailing after levigate screening largely belongs to ultra fine sand, fine sand scope, and containing a certain amount of
The features such as stone flour, as building sand directly using at present it is relatively difficult, the use of mixed sand can technically overcome iron tail
The shortcomings that ore deposit disproportionately graded, particularly adopting iron ore tailings, change the defects of iron milltailings particle diameter is partially thin with Machine-made Sand recombination energy, make grading
Rationally.CHARACTERISTICS OF TAILINGS SAND can also reduce the content of stone powder in CHARACTERISTICS OF TAILINGS SAND with the compound use of Machine-made Sand simultaneously.Iron tailings in mixed sand
