Description
Technical field
The present invention relates to chemical building material technical field, more particularly to a kind of waste and old concrete regeneration aggregate surface treatment
Device and method.
Background technology
During building waste cycling and reutilization produces regeneration concrete, by discarded concrete, fragment of brick through it is broken,
Regeneration concrete is prepared as regeneration aggregate after screening and occupy very important status, and realize that building waste is sharp again at present
Main path.Regeneration aggregate is that there are mortar attachment, Regenerated Bone in the surface of regeneration aggregate applied to concrete main bottleneck
Microcrack be present in the attachment of material micro mist, aggregate matrix.The old mortar strength of attachment is low, low with cement slurry bond strength.Again
Raw micro mist main component is stone flour, cement stone dust, soil, is non-sticky inorganic matter, equally also result in regeneration aggregate with it is new
Mix slurries faying face weakness.Microscopic checks in aggregate matrix causes regeneration aggregate water absorption big, aggregate low intensity.These are unfavorable
The regeneration concrete various aspects of performance that factor all makes to make substantially is inferior to natural aggregate concrete, it is impossible to prepares high-grade mix
Solidifying soil, limits recycling for building waste.
It is to improve the effective way of regeneration aggregate quality that intensive treatment is carried out to regeneration aggregate, and its main method is aggregate table
Face is modified.At present, conventional aggregate surface modification method has two kinds of Physical and chemical method.Physical strengthening method mainly passes through
Plant equipment is handled the aggregate after crushing, and by regeneration aggregate and itself or extraneous friction, is removed surface laitance, is reached
Strengthen the purpose of aggregate.This kind of method high energy consumption, and aggregate basal body structure can be damaged.Chemical method is mainly utilizationization
The peculiar property of slurries is learned, the processing such as is impregnated, eluted, dried to regeneration aggregate, reaches the purpose that aggregate is strengthened.Chemistry side
Method is divided to two kinds, and one kind uses inorganic slurry, and another kind uses organic slurry.Inorganic slurry mainly has cement mortar, cement mortar+fine
Mineral admixture, cement mortar+KIM powder are several.KIM powder is a kind of high effect leakage proof waterproof of Canadian Kaidunbaisen company production
Agent.Simple cement mortar or cement mortar+Separate Fine-grained Minerals admixture do not have invigoration effect to aggregate, and cement mortar+KIM has certain effect
Fruit, this can penetrate into aggregate mainly due to KIM powder and be internally formed crystal, also improve aggregate intensity.Organic procedures are mainly
Regeneration aggregate is impregnated using solution of silane and PVA (polyvinyl alcohol) solution.The regeneration aggregate impregnated via organic solution
Water absorption rate has a certain degree of decline.More than the method for chemical grout dipping complex process be present, cumbersome lack
Point.And simply improve aggregate matrix strength or reduce the water absorption rate of regeneration aggregate, do not solve regeneration aggregate circle
Face is combined the problem of poor with cement slurry.
The content of the invention
The problem of poor, mesh of the invention are combined with cement slurry for existing waste and old concrete regeneration aggregate interface
Be to provide a kind of waste and old concrete regeneration aggregate surface processing device that can effectively improve regeneration concrete overall performance and
Method.

First, waste and old concrete regeneration aggregate surface processing device of the invention and method, pass through the skin of interconnection first
Surface processing device with machine, liquid bed and chain net type conveyer composition, liquid bed, liquid are delivered to by regeneration aggregate via belt feeder
Hydrated calcium silicate gel solution is placed in bed；Chain net type conveyer drives regeneration aggregate to be moved in liquid bed；Last vibrating motor
Band hydrodynamic bed and the vibrations of hydrated calcium silicate gel solution and regeneration aggregate so that hydrated calcium silicate gel solution equably wraps up
On regeneration aggregate surface.Regeneration aggregate by the vibrations of liquid bed processing after, can effectively remove originally be attached to it is inviscid on aggregate
Micro mist, to be clipped in the micro mist in gap it is also possible to shake.Hydrated calcium silicate gel solution can uniformly be wrapped in regeneration aggregate
The defects of surface is filled into aggregate surface simultaneously.The regeneration aggregate handled by liquid bed can directly be regenerated instead of natural aggregate
The stirring of concrete, need not move through and the step such as dry.After being contacted with cement slurry, hydrated calcium silicate gel solution can effectively promote
Enter the development of cement strength around regeneration aggregate, while gel solution can combine together with the Behavior of Hardened Cement Paste around aggregate.This
Sample, the intensity of regeneration aggregate and cement slurry linkage interface is just effectively increased, so as to effectively increase regeneration concrete
Overall performance.
2nd, waste and old concrete regeneration aggregate surface processing device and method of the invention provide a kind of new to regeneration
The method that aggregate carries out intensive treatment, i.e., regeneration concrete is carried out again after soaking regeneration aggregate with hydrated calcium silicate gel solution
Stirring.Regeneration aggregate is handled using this method, hydrated calcium silicate gel solution can fill microdefect and parcel on regeneration aggregate
On regeneration aggregate surface.Treated intensifying regenerating aggregate can be directly used for regeneration concrete production, enter again after can also drying
The production of row regeneration concrete.Party's forensic science is feasible, and the corollary equipment of mechanization processing can also be with existing concrete bone
Material induction system is integrated, and effectively increases the production efficiency of regeneration concrete.
