In will produce a large amount of building waste.The landfill of building waste with the unreasonable disposition such as stack, not only can land occupation resource, together
When will also result in serious pollution to soil, water source and air.It is substantially not useless to build solid waste, is put in wrong time
Resource in wrong place is precious deposits and " the city mine " of mispairing.It, can by recycling processing, recycling or other measures
Directly become product or be converted into the secondary raw material of recycling, mitigated and even avoid its harm, available good economy,
Society and environmental benefit.Construction refuse regenerated aggregate is applied to cement stabilizing regenerative granular material base (recycled water is steady), it can be maximum
Realize to limit the green utilization of building waste.
Surely middle cement consumption (is generally not less than 3%, not higher than 7%), 7 days without lateral spacing resistance to compression to recycled water for 5% or so
Intensity also has certain promotion in 3.6MPa or so, with 7 days unconfined compressive strengths of promotion of cement consumption, but is usually no more than
4.4MPa, and low compression strength can limit the steady application range and service life of recycled water.
For the reason of the above situation occurs other than the defect of recycled aggregate itself, Another reason also resides in a small amount of cement
Can not be uniformly dispersed during mix so that recycled water it is steady integral strength it is not high.For the above situation, engineering is answered at present
It uses water-reducing agent to increase cement dispersibility in more, is also that current application is most using polycarboxylate water-reducer as water-reducing agent of new generation
Water-reducing agent.But since polycarboxylate water-reducer is more sensitive to the content of soil in aggregate in use, and regenerated aggregate
Middle fine aggregate (grain size<It is 0.075mm, follow-up to be referred to as " regeneration soil ") content 4% or so, with cement consumption phase therein
When, regeneration soil can inhibit dispersion of the polycarboxylate water-reducer to cement, or even failure, eventually lead to cement in recycled water is steady according to
Old uniformly to disperse, when solidification, cannot form complete solid space structure, surely strong to play enhancing recycled water
The effect of degree.
In order to solve influence of the regeneration soil to polycarboxylate water-reducer, common method is that the direct polycarboxylate water-reducer that increases is used
Amount, but increases of polycarboxylate water-reducer dosage not only results in the increase of production cost, simultaneously because volume is excessively and in turn
Influence the steady intensity of recycled water.
In addition, also have by way of being compounded with other anti-mud agent to reach requirement, but these anti-mud agent are most
Number is applied in concrete, the soil for the middle doping that is primarily directed to newly to gather materials, such as montmorillonite, kaolin, and for poly-
Carboxylic acid water reducer recycled water does not surely carry out relevant research with anti-mud agent, also without application example.
Therefore, develop it is a kind of can effectively inhibit to regenerate the anti-mud agent that soil influences polycarboxylate water-reducer it is most important.
