Abstract
The invention discloses dry-mixed plastering mortar of replacing part of fly ash with stone flour. The dry-mixed plastering mortar is prepared from the following raw materials: 750-800 kg of tailings aggregate, 120-160 kg of cement, 40-65 kg of fly ash, 45-70 kg of stone flour, 4-6 kg of a water reducer and 20-50 kg of an additive. The tailings aggregate is prepared by the use of mine tailings, and the sources are wide. In addition, the stone flour used in the invention is stone flour generated during machine-made sand making process of stone waste generated during production of the tailings aggregate. The stone flour generated during production of the tailings aggregate is fully utilized to replace part of fly ash. Resources recovery reutilization rate is high, energy is saved and emission is reduced. Production cost of the dry-mixed mortar is greatly reduced, and the economic benefit is high.
Description
Technical field
The present invention relates to the new green environment protection energy saving building building materials field of green building material, scrap concrete recycling, particularly related to a kind of stone powder and replaced the dry-mixed plastering mortar of part flyash.
Background technology
Dry-mixed mortar is generally hydraulic cement mixed mortar, refer to that aggregate, inorganic coagulation material and the additive etc. that drying screening processes carry out a kind of graininess or the powdery of physical mixed by a certain percentage, being transported to building site with form packed or in bulk, add water the material that can directly use after mixing and stirring. It is extremely wide that dry-mixed mortar plays bonding, liner, protection and decoration function, building and fitting-out work application with thin layer in building industry. Wherein prepare dry-mixed mortar to need to consume substantial amounts of natural sand. China is big steel country, and iron mine is based on lean ore, and the waste tailings therefore producing essence iron powder is very abundant, and its discharge is generally adopted tailing dam (storehouse) and concentrates stacking, not only land occupation, and contaminated environment. Utilizing mine tailing replacement natural sand to prepare dry-mixed mortar technology is a kind of not only twice laid but also the comprehensive utilization technique of energy-conserving and environment-protective.
Mine tailing is one of product of separation operation in ore dressing, and the part that wherein useful target components content is minimum is called mine tailing. Under current condition of technology and economy, should not further sort. But along with the development of Manufacturing science technology, useful target components there may also be the economic worth of recycling further. Mine tailing is not completely written-off waste material, often contains the component that can make other purposes, it is possible to comprehensive utilization. Realize no waste mine discharge, be the mineral resources needs being fully used and preserve the ecological environment.
And mine tailing is a kind of resource at the stone powder that the broken aggregate chips being classified into mine tailing aggregate and produce produces in the process of Machine-made Sand sand, it is very unfortunate for can not being fully utilized, process as solid waste, cause very big waste, also serious pollution can be brought to environment, stone powder is through reasonably utilizing, the management of science and control, in dry-mixed mortar produces, considerable income can be brought, the performance of dry-mixed mortar can be improved again, the quality of dry-mixed mortar there is a lot of liftings, meet the fundamental policy setting up conservation-minded society that China advocates, to major part enterprise self, stone powder need not also be waste, land occupation, environment and image to enterprise are also have certain harmful effect.If stone powder is fully utilized, it is possible to solve the difficult problem that enterprise's dry-mixed mortar cost is high, to enterprise under the current stagnant overall situation of building trade, have found new profit growth point, improve the core competitiveness of enterprise. But the stone powder selecting crude drugs with winnower that Machine-made Sand produces is not collected by enterprise at present, but is mixed in 10-30mm stone and 5-15mm stone, and resource recycling rate is low. In actual production, stone powder consumption can not get effective control, and the quality of stone powder also can not get keyholed back plate, and quality can not get ensureing, quality risk is higher. Under nowadays architectural environment, recovery of the capital is very big problem, and quality goes wrong and easily causes downstream client and embezzle part of what should be issued the excuse of engineering funds, and cost has high input, and economic benefit is low.
Therefore, in order to solve above-mentioned Problems existing, spy of the present invention provides a kind of new technical scheme.
Summary of the invention
It is an object of the invention to provide a kind of stone powder and replaced the dry-mixed plastering mortar of part flyash, it is possible to solve the technical barrier that existing dry-mixed mortar cost is high, recycling of recyclable waste reuse ratio is low.
The present invention is directed to above-mentioned technological deficiency be the technical scheme is that
A kind of stone powder replaces the dry-mixed plastering mortar of part flyash, it is characterised in that: the raw material including following weight is made:
Mine tailing aggregate 750-800kg;
Cement 120-160kg;
Flyash 40-65kg;
Stone powder 45-70kg;
Water reducer 4-6kg;
Additive 20-50kg.
Further, described mine tailing aggregate is that mine tailing stone forms through broken classification.
Further, described mine tailing aggregate is the granule less than 5mm after drying filtration treatment.
Further, described cement is one or more the combination in portland cement, sulphate aluminium cement, alumina cement.
Further, described water reducer is one or more the combination in melamine condensates, sulfamate condensation substance.
The preparation method that it is a further object of the present invention to provide stone powder in a kind of dry-mixed plastering mortar, concrete preparation method is as follows:
A, mine tailing is crushed the stone powder selecting crude drugs with winnower that the aggregate chips being classified as mine tailing aggregate and produce produces in Machine-made Sand sand collect;
B, by selecting crude drugs with winnower collect stone powder select powder by cyclone separator, coarse powder continue crush, fine powder blows into stone powder storage vault by ventilation skewed slot;
C, stone powder be homogenizing in stone powder storehouse, then enter conveying worm be transported in cement flour truck, then get to the stone powder storehouse of mortar mixing plant.
The invention has the beneficial effects as follows: the present invention adopts mine tailing to prepare mine tailing aggregate, wide material sources, and stone powder adopts the stone powder that the aggregate chips that mine tailing aggregate produces in producing produces in Machine-made Sand sand process, the stone powder that mine tailing aggregate produces in producing is utilized to replace part flyash fully, resource recycling rate is high, energy-saving and emission-reduction, greatly reduce the production cost of dry-mixed mortar, high financial profit.
