Abstract
The invention relates to construction waste micro-powder composite stabilized soil. The stabilized soil consists of the following components: dry soil, cement, lime, construction waste micro-powder and water at a mass ratio of 100:(2-8):(4-12):(4-10):(10-20). The construction waste micro-powder composite stabilized soil can be used for realizing mass utilization of construction waste micro-powder, relieving pollution of construction solid waste on environment, saving cement and lime, and saving natural resource and energy.
Description
Technical field
The invention belongs to pavement construction material technical field, be specifically related to a kind of comprehensive stable soil with building waste micro mist part place of cement and lime, for roadbase and subbase.
Background technology
Building waste is a kind of effectively construction refuse resource approach for the production of processing regenerated aggregate.But in the process of regeneration aggregate fragmentation, screening and particle shaping, inevitably can produce fine powder, these fine powders need screen out, otherwise can affect the quality of regeneration aggregate.Conventionally the fine powder of nominal particle diameter≤0.08mm in the regeneration aggregate course of processing is called to building waste micro mist, building waste micro mist accounts for 10% left and right of regeneration aggregate quality.Chemical analysis and XRD analysis show, the main component of building waste micro mist comprises a large amount of grout powder, part of cement stone granulate and a small amount of Wingdale fine particle, has lateral reactivity, so this part fine powder material can be used by research.The composite gelled material made from building waste micro mist place of cement or other mineral adulterant is for the existing a lot of reports of achievement in research of concrete aspect.But the Stabilized Soil that building waste micro mist is used for roadbase and subbase, correlative study and report are also seldom.
In Road construction, be located immediately in the basic unit and the subbase below basic unit under top course, use in a large number stabilized with inorganic binder soil.Wherein, with the compound that cement or lime obtain as certain native binder, be called cement stabilized soil and lime stabilized soil, use cement and lime as the compound of certain native binder, referred to as comprehensive stable soil simultaneously.At present, take the industrial residues such as flyash, cinder, slag is that main industrial waste is also widely applied in lime industrial residue Stabilized Soil.And building waste micro mist is as a kind of solid waste, to use it in Stabilized Soil, the secondary combined material as cement and lime, has a good application prospect too.
Summary of the invention
The present invention is using building waste micro mist as cement with the secondary combined material of lime, for comprehensive stable soil, and part place of cement and lime.The comprehensive stable soil unconfined compression strength obtaining meets the related request of < < highway road surface construction technique normalizing > > JTJ034 ?2000, and shrinkage performance is also better than common comprehensive stable soil.
The mass ratio of each component of building waste micro mist comprehensive stable soil involved in the present invention is as follows: dry ground: cement: lime: building waste micro mist: water=100:(2～8): (4～12): (4～10): (10～20).
Cement of the present invention is one or more in ordinary Portland cement, Portland blast furnace slag cement, Portland pozzolana cement, and cement mark is 325 or 425.
Lime of the present invention is one or more in calcareous unslaked lime, magnesia unslaked lime, calcareous slaked lime and magnesia slaked lime, effective calcium-magnesium content >=60% of calcareous unslaked lime and calcareous slaked lime wherein, effective calcium-magnesium content >=55% of magnesia unslaked lime and magnesia slaked lime.
One or more in waste cement concrete, waste cement mortar, discarded brick and tile and discarded architectural pottery of building waste of the present invention form.
Building waste micro mist of the present invention is that produce with milling equipment, nominal particle diameter≤0.08mm, specific surface area>=300m that above-mentioned building waste generates in being broken for regeneration aggregate or direct
2the powder material of/kg.
Dry ground of the present invention is that plasticity index is at more than 8 viscosity dry ground.
Water of the present invention is tap water (containing livestock drinking water).
The production method of building waste micro mist comprehensive stable soil of the present invention is: by weight proportion the material beyond dewatering is added in mixing machine, mix, after 3～5 minutes, adds water by weight proportion, then mix evenly.
The present invention can utilize building waste micro mist in a large number, reduces the pollution of building solid castoff to environment, saves cement and lime, saves natural resources and the energy.
Embodiment
In proper mass proportioning, be dry ground: on the basis of the comprehensive stable soil of cement: lime=100:4:8, with building waste micro mist, replace respectively 1 part of cement and 3 parts of lime, obtain the comprehensive stable soil proportioning of following concrete ratio.
Plasticity index is 12 clay: 100kg;
325 ordinary Portland cements: 3kg;
Calcareous slaked lime: 5kg;
Building waste micro mist: 4kg;
Tap water: 17.7kg
The maximum dry density of above Stabilized Soil is 1.76g/cm
3, optimum moisture content is 15.8%.Take in proportion above material, test method according to < < highway engineering stabilized with inorganic binder testing of materials rules > > (JTJ E51) regulation is made test specimen, compactness 99%.After maintenance 7 days, surveying its 7d unconfined compression strength is 2.6Mpa, and the coefficient of shrinkage is 62% of former proportioning comprehensive stable soil.
The production method of building waste micro mist comprehensive stable soil of the present invention is: by weight proportion the material beyond dewatering is added in mixing machine, mix, after 3～5 minutes, adds water by weight proportion, then mix evenly.
