Background technique
With the continuous development of concrete technology, the performance of concrete is improved, and cost and energy consumption reduce, the application of concrete
Field is widened, and the current concrete annual output in China is very big, needs to consume many natural aggregates, in aggregate production use process
Brought ore resource, the consumption of the energy and the general of global range is caused to the pollution problem of atmosphere and environment
All over concern.
At present the resource utilization of lime-ash specifically include that the raw material of eco-cement, concrete and pitch aggregate substitute,
The gathering materials of road engineering, the covering material of landfill yard and brick setting prepare material etc..Natural soft-clay is compared with aggregate, lime-ash
It is a kind of material than relatively lightweight, water absorbing capacity is strong.Its engineering characteristic shows that it meets the multiple technologies as aggregate and gravel
It is required that and be easy to carry out partial size distribution, many scientific research personnel attempt to utilize urban household garbage incineration residue in concrete
Abrasive micropowder, analysis micro mist recycle feasibility and improve substitution rate etc. of the micro mist in concrete.
Summary of the invention
Goal of the invention: aiming at the problems existing in the prior art, the present invention is provided one kind and is made with domestic refuse incineration ash
For the concrete and preparation method thereof of admixture, it can be effectively improved the interface performance of Behavior of Hardened Cement Paste aggregate, porosity is reduced, make to mix
Solidifying soil is finer and close, to effectively increase the pressure-proof and snap-resistent intensity of concrete.
Technical solution: the concrete that the present invention provides a kind of using domestic refuse incineration ash as admixture, by following
The group of parts by weight is grouped as: 2.5 ~ 5 parts of domestic refuse incineration ash, 1 ~ 3 part of silicon ash, and 1 ~ 2.5 part of flyash, 8 ~ 13 parts of cement,
45 ~ 50 parts of stone, 26 ~ 30 parts of sand, 5 ~ 8 parts of water and 0.1 ~ 0.2 part of water-reducing agent.
The present invention also provides a kind of using domestic refuse incineration ash as the preparation method of the concrete of admixture, including with
Lower step: S1: by domestic refuse incineration ash, drying to constant weight under conditions of 120 DEG C；S2: by the consumer waste incineration
It is 8000 ~ 9000 that lime-ash, which is ground into specific surface area,Lime-ash micro mist, and lime-ash is added thereto during grinding
The calcium hydroxide that weight is 1 ~ 2%；S3: by the lime-ash micro mist and silicon ash, flyash, cement, stone, sand, water and water-reducing agent
It is uniformly mixed to obtain the concrete.
The utility model has the advantages that compared with prior art, the present invention having the advantage that
(1) lime-ash that the present invention generates consumer waste incineration carries out grinding and prepares micro mist, utilizes the mixed of micro mist preparation after drying
Solidifying soil, has the characteristics that higher intensity, lightweight, energy-saving and environmental protection.
(2) lime-ash is carried out superfine grinding by the present invention, and the grain composition of cementitious material is improved after incorporation concrete, can
Effective fill concrete hole, and the interface performance of Behavior of Hardened Cement Paste aggregate is improved, porosity is reduced, causes concrete more
It is close, to effectively increase the pressure-proof and snap-resistent intensity of concrete.
(3) domestic refuse incineration ash is applied to concrete, on the one hand will reduce since lime-ash is stacked for land resource
Occupancy and pollution to natural environments such as soil, empty gas and waters, be conducive to environmental protection, meet the strategy of sustainable development；It is another
Aspect can save cement consumption, alleviate the energy, resource consumption due to caused by the mass production of cement and caused by dust,
The environmental pollutions such as water, and the progress and development for having pushed modern concrete to study to a certain extent, also can be that society brings
Huge economy and environmental benefit have huge development space, have a extensive future.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.
Embodiment 1:
