Abstract
The invention discloses a construction waste concrete brick and a method for making the same. The concrete brick is prepared by mixing the following raw materials: 15 to 35 portions of construction waste concrete, 50 to 70 portions of construction waste brick dust and 10 to 15 portions of cement. The method for making the brick is as follows: construction wastes are sorted and sieved so as to be mixed and stirred with other raw materials; wet basis water content is controlled between 12 and 16 percent; the mixed materials are formed under a pressure of between 15 and 35 MPa; and a formed brick undergoes natural curing or steam curing. The product meets the requirements of the agricultural industry standards of the people's republic of china, i.e. the 'Concrete Common Brick and Decorative Brick' (NY/T671-2003), and the strength of the product can reach to above MU10. The technology ensures that the total use of construction waste reaches to above 85 percent, and has the advantages of no sintering, low energy consumption and no exhaust emission, etc.; moreover, the technology solves the problems of the prior construction waste wall brick process such as low treatment efficiency of construction waste, more raw materials, high cost of a jelling material and poor market applicability; meanwhile, the technology accords with national energy-saving and emission-reduction policies, and has enormous environmental benefit, economic benefit and social benefit.
Description
Technical field
The invention belongs to made from construction refuse resource and utilize technical field, be specifically related to a kind of concrete brick and production method thereof of utilizing building waste for raw material production.
Background technology
Be accompanied by developing rapidly of construction industry, the building waste that is produced by construction industry also unprecedentedly increases.China has 40,000,000,000 m now
2Building mostly will be converted into building solid castoff in following 100 years.Produce building solid castoff at present China's year more than 300,000,000 tons, existing disposal options is mainly based on landfill.The building waste of flood tide also causes a lot of environmental problems and social effects of pollution except processing costs is quite surprising.
Country also progressively strengthens the protection to land resources, and the coal resources price continues high, utilizes vitrified bond to become the technology of brick progressively to be eliminated in the past, and what replace will be to need not sintering, and main raw material is solid useless no-firing brick.State Economic and Trade Commission determines that 170 big and medium-sized cities, the whole nation will ban use of solid clay brick in limited time before 30 days June in 2003, also require other provincial capitals also will realize banning use of the target of solid clay brick at the latest before the end of the year 2005.Utilize building waste to prepare wall body brick, both eliminated building waste and stacked the environmental problem that causes, the substitute products of the solid vitrified brick of a kind of clay are provided again.Domestic the development partly utilizes building waste to prepare the research of wall body brick.
Building waste has at the main patent documentation aspect other concrete bricks of production:
Chinese patent literature " building refuse concrete perforated brick and manufacture method thereof " (publication number CN101148340, open day on 03 26th, 2008) in, its weight percentages of components is coarse aggregate 20-25 part, fine aggregate 50-55 part, cement 15-18 part, slightly wet ash discharge 10-12 part, water-solid ratio 13～15%.Shortcoming is that cement mixing content is big, and cost is higher, near the slightly wet in addition ash discharge ingredient requirement brick field coal-burning power plant is arranged.
Chinese patent literature " adopting the building block of building waste preparation " (publication number CN101157532, open day on 04 09th, 2008) in, building waste 65-70 part, compound 30-35 part, admixture: be dissolved in 6-8 part water by sodium abietate 0.2-0.4 part, tripoly phosphate sodium STPP 0.1-0.3 part and make; Compound is by forming flyash, slag or coal gangue 13-16 part, carbide slag or lime powder 7-9 part, phosphogypsum or terra alba 2.5-4 part and the mixing of refuse clay brick particle 7-9 part, raw material technology is comparatively loaded down with trivial details, during especially raw material mixes fineness to be controlled at 180 mesh standard sieve screen over-sizes 40～60% difficult.
In general, in the building waste wall body brick technology in the past, the building waste processing efficiency is low, and the raw material number is many, and the gelling material cost is higher, and market applicability is relatively poor.
Summary of the invention
