Abstract
The invention discloses a kind of composite blending material for concrete of environmental protection, each component and its mass percentage content are：Clinker 5-20%, concrete filter residue 10-80%, waste concrete test block 10-80%, grinding aid 0.1-0.5%；The summation of above-mentioned each component mass percentage content is 100%；The concrete filter residue is the filter residue formed through precipitation, after filter-press dehydration after ready-mixed concrete manufacturing enterprise Sewage treatment；The waste concrete test block is the test specimen for being used to detect compression strength by concrete formation, the waste material formed after testing after testing.There is the composite blend of the present invention a large amount of produced using the low cost such as discarded object to meet National Standards Technical specification, the composite blending material for concrete of environmental protection.
Description
Technical field
The invention belongs to concrete field, more particularly to a kind of composite blending material for concrete of environmental protection.
Background technology
Composite blending material for concrete builds work professional standard mainly for the production of ready-mixed concrete, according to what the firmly portion of building was promulgated
JG/T486-2015《Composite blending material for concrete》Standard requirement, masonry cement is mixed by two or more mineral
Close material and be mixed into uniform powder body material by a certain percentage；Or by two or more raw mineral materials, by a certain percentage
After mixing, proper amount of gypsum and grinding aid can be filled if necessary, then grinding is to the powder body material of certain fineness.
At present, the waste water that ready-mixed concrete production process is produced, finds no to recycle and uses compound in production concrete
Admixture.
The content of the invention
Meet national standard skill the technical problem to be solved in the present invention is to provide a large amount of produced using discarded object low cost
Art specification, the composite blending material for concrete of environmental protection.
The present invention solves above-mentioned technical problem with following technical scheme：
A kind of composite blending material for concrete of environmental protection, each component and its mass percentage content are：
Clinker 5-20%；
Concrete filter residue 10-80%；
Waste concrete test block 10-80%；
Grinding aid 0.1-0.5%；
The summation of above-mentioned each component mass percentage content is 100%；
The clinker is to meet standard GB/T/T21372《Portland clinker》Clinker；
Formed after the Sewage treatment that the concrete filter residue produces for production ready-mixed concrete after precipitation, filter-press dehydration
Filter residue；
The waste concrete test block is the test specimen for being used to detect compression strength by concrete formation, shape after testing after testing
Into waste material；
The grinding aid is to meet standard GB/T/T26748《Cement grinding aid》Grinding aid.
A kind of preparation method of the composite blending material for concrete of environmental protection, by the clinker, concrete filter residue
With waste concrete test block, content is mixed by mass percentage after drying is broken respectively, then fills grinding aid, then grinding.
The composite blending material for concrete of environmental protection of the present invention has advantages below：
1st, work professional standard JG/T486-2015 is built meeting《Composite blending material for concrete》Demand of technical standard under,
A large amount of to make use of trade waste, trade waste content can exceed the 80% of gross mass, and green, environmental protection are prominent.Manufacturing cost
Low, technique is simple, it is not necessary to buys lime stone, commercial fly ashes, commodity slag or slag, protects national resources and resource again
Utilize.Meet national industry development policies and the strategy of sustainable development turned waste into wealth.
2nd, the composite blending material for concrete of environmental protection of the present invention, is fully achieved and builds work professional standard JG/T486-2015
《Composite blending material for concrete》The technical requirement of III grade of middle plain edition and the above.
3rd, the composite blending material for concrete of environmental protection of the present invention, work professional standard JG/T486-2015 is built with meeting
《Composite blending material for concrete》Other composite blending material for concrete of the constructed index of plain edition compare, cost reduction by 50
Member/more than t.
