Abstract
The invention discloses a construction-waste-adopted firing-free solid brick. The construction-waste-adopted firing-free solid brick is prepared from mortar through a brick making machine. The mortar is prepared from cement, lime putty, construction waste and water in a mixed mode, wherein the mass ratio of the cement to the lime putty to the construction waste is 1:(0.25-1.35):(5.5-11.15). The grade of the selected cement is four to five times that of the mortar. The construction waste is smashed with a smashing machine, and construction waste with the mass of particles with the particle size lager than 0.25 mm larger than 50% of the total mass is obtained. The lime putty is obtained in the mode that quick lime is cured into lime putty, and the lime putty is filtered with a net and sufficiently cured for no less than 7 days. The denseness of the mortar is 7 cm to 10 cm. According to the construction-waste-adopted firing-free solid brick, the pollution of the construction waste to the environment is reduced, and a new material is added for constructional engineering; the firing-free solid brick meets the national standard for building bricks, and has the advantages of being high in strength, free of pollution, resistant to freeze thawing, low in cost and the like; waste building demolishing waste can be recycled, the production cost of a building brick can be reduced, and high social and economic benefits can be achieved.
Description
Technical field
The present invention relates to building material technical field, specifically a kind of unburned solid brick of utilization building waste.
Background technology
In recent years, with the continuous development of national economy, define the upsurge of urban renewal throughout the country, exist everywhere
" tearing down and building greatly " and " big construction ", can produce substantial amounts of discarded concrete and building brick etc. inorganic in the demolishing process of building
Nonmetallic materials class building waste.The process of building waste has become a great problem of urban construction.Rapid digestion and comprehensive profit
With building waste, become the task of top priority.
At present, these building wastes are substantially poured into soot, take the mode of enveloping field landfill, this measure, both take
Substantial amounts of soil, consumes manpower and materials again, and the hidden danger of simultaneously buried lower secondary pollution causes the waste of resource, building
The utilization of the building waste that thing is removed is also extremely urgent；And on the other hand, all kinds of architectural engineerings need substantial amounts of building brick again,
Limited use with traditional clay brick, shale brick and normal concrete brick price are higher, occur in that using various discarded objects
Flyash the like waste makes building brick, such as flyash etc..And in the production and application process of the reality taken for many years,
Building waste sinters brickmaking, the transform mode such as cement concrete construction garbage brick, exists that the useless rate of profit is low, and product strength is inclined
Low, material water absorption rate is high, the problems such as contract with dry rate is big, and in process of production, due to some product processes high energy consumptions, produces
The reasons such as secondary pollution, are accordingly difficult to popularize in an all-round way and utilize.
Content of the invention
It is an object of the invention to provide a kind of intensity is high, pollution-free, the exempting from using building waste of freeze thawing resistance, low cost
Burn solid brick, to solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme：
A kind of unburned solid brick of utilization building waste, is made up through brickmaking machine of mortar, mortar is according to cement: lime paste
: building waste=1: 0.25-1.35: 5.5-11.15 mass ratio is simultaneously mixed with water.
As the further scheme of the present invention：4-5 times of label being numbered mortar from cement.
As the further scheme of the present invention：Building waste is pulverized by pulverizer, obtain particle diameter be more than 0.25mm
Grain quality exceedes the building waste of the 50% of gross mass, and the clay content of building waste is less than 5%.
As the further scheme of the present invention：Grade of mortar cannot be less than equal to No. 50.
As the further scheme of the present invention：Lime paste is that quick lime is cured into lime paste, with net filtration, and so that it is filled
Divide curing, the curing time must not be less than 7 days.
As the further scheme of the present invention：Water is using the clean water without harmful substance.
As the further scheme of the present invention：Consistency of mortar is 7-10cm.
As the further scheme of the present invention：Cement: lime paste: the mass ratio of building waste is 1: 0.5-1: 6.5-9.
Compared with prior art, the invention has the beneficial effects as follows：
It is primary raw material that the present invention adopts building rubbish, makes unburned reality with cement, lime paste by dispensing and shaping
Heart brick, had both decreased the pollution to environment for the building waste, increased new material, the unburned reality of present invention preparation for architectural engineering again
Heart brick reaches the standard of national building brick, have that intensity is high, pollution-free, freeze thawing resistance, low cost the features such as, simultaneously can greatly
Fast China abandoned building removes the recycling process of rubbish.The present invention both can achieve that abandoned building removed the money of rubbish
Sourceization utilizes, and reduces the production cost of building brick, thus has larger Social and economic benef@.
