Abstract
A solidifying agent used for soil and building garbage to make the brick by die presisng and natural curing or for treating the bed of road or railway is disclosed. Its advantages are high effect and low cost.
Description
Technical field the present invention relates to that a kind of soil and building waste solidified material of being used for---special Saite solidifying agent difficult to understand the invention belongs to building material field.
The handled soil of background technology the present invention is mainly used in the more unmanageable or engineering that has higher requirements such as water conservancy imperviousing preventing flushing brush, flabbiness ground strengthened processing, road and rail subgrade strengthening.The handled building waste of the present invention is meant because the city layout adjustment, urban planning construction, development of real estate, dilapidated house are pulled down and removed a building for reconstruction in the process, waste and old concrete, grit, brick and tile, lime and a spot of pottery that forms, glass, soil etc. do not comprise metal, timber, pitch and organic domestic waste etc.
Along with the rapid growth of economic construction, environment protection and Sustainable development further worsen, and environmental requirement improves day by day.This protrusion phenomenon in building materials field, the one, a large amount of stackings of urban architecture rubbish form the new pollution in city; The 2nd, solid clay brick destroys and ploughs, the mass consumption energy.Though the new wall materials layer goes out not group on the market, as structural clay tile, haydite holllow building block, concrete hollow block, autoclave aerated concrete building block and all kinds of wallboards etc., but aspect bearing wall material, still there is not suitable material to substitute solid clay brick.Mentougou District, Beijing utilizes shale and coal gangue to produce the sintering solid clay brick at present, but still obviously has the defective of environmental protection aspect.
" naturally-cured powdered coal ash brick " patent of invention of patent " 89102223.6 " discloses a kind of flyash that utilizes and has made non-burning brick technological method, it uses flyash and sand, silicate cement and alkaline earth metal halide, through stirring, extrusion forming, hardening treatment become flyash brick.Hydraulic cinder brick, the piece of patent " CN1117030A " have then utilized solid waste, replace Tu Yuan as lime-ash, slag, slag etc., manufacture experimently out to contain cindery hydraulicity solidifying agent.
Above patent differs from one another, but still comes with some shortcomings when solidify material, and as 1, when solidifying silt or containing the thinner powder of particle, intensity there is no obvious raising.2, lime-ash or flyash brick all need to add a large amount of sands, have obviously increased cost.3, the main purpose of patent is how to digest lime-ash and flyash, is applied in the problem that the materials for wall aspect also exists intensity and weather resistance.4, the storage of lime-ash or flyash is not enough to provide the quantity-produced amount, and utilization ratio is not high.
Patent 1125702 provides a kind of lime firming agent for soil, utilizes unslaked lime, anhydrite, sodium sulfate and Tai-Ace S 150 combined grinding to specific surface area 300～500m
2/ kg.Patent 1131131 provides a kind of cement-like soil firming agent, utilizes Portland clinker, anhydrite, glycerol combined grinding to specific surface area 300～500m
2/ kg.Patent 1107500 provides a kind of soil modifier of stable soil making roadbed, has utilized alkyl benzene sulphonate (ABS), polysiloxane phosphoric acid, polyacrylic acid, lipid acid, polyvinyl alcohol to make emulsion.More than three kinds of patents characteristics are respectively arranged, but still have some shortcomings during curing soil, three kinds of solidifying agent all can't be handled the loam inferior in the engineerings such as the mud, collapsible loess, saline soil of high liquid plastic limit high organic.
Summary of the invention the purpose of this invention is to provide a kind of can solidification treatment building waste pellet extrusion forming standard solid brick, and maintenance reaches national building material industry standard " non-sintered common clay brick " every index request (JC422-91) under normal temperature condition.Its purposes can be as various building blocks of functions such as load-bearing and non-bearing wall body material, pavement brick, slope protecting components.
Another object of the present invention is the solidifying agent that provided can also be handled the various complexity that run in highway, railway, water conservancy, soft foundation treatment project a soil.The solidifying agent Stabilized Soil is as road basement material, and its performance can satisfy the rules requirement of national building material industry standard CJJ/J80-98.
High-performance special Saite solidifying agent difficult to understand is a kind of powdery solid, add the special inorganic materials that excites element to obtain and be main cement based organic polymer composite, this well behaved solidify material for general low in liquid limit clay, river sand, saprolite and contain organic higher mud etc. very significant stable curing effect is all arranged.Can be used for road and rail roadbed, water conservancy channel, lakebed and solidify in antiseepage antiscour, the soft foundation treatment project, compare, have that intensity height, barrier performance are good, antiscour, pollution are little, short construction period, the low characteristics of comprehensive cost with traditional technology.High-performance special Saite solidifying agent difficult to understand is as soil-stabilising material, can handle the engineering special soil that stable material such as cement and lime can't be handled, and as mud, powder fine earth etc., its intensity is compared with the cement of volume and wanted high by 50%～200%.
The exploitation that utilizes building waste to prepare unburned solid standard square curing technology, have save coal-fired, save mineral wealth, improve environment, advantage such as reduce cost.Its principle is summarized as follows:
The cement of coming of new, brick and tile are used on buildings or the structures, and after the use several years, owing to multiple reason, buildings or structures must be scrapped, remove, so become building waste.As building waste itself, by classification analysis, can be clear that there is difference in they on chemical ingredients and mineralogical composition, different chemically reactives is arranged, if it is simply passed through fragmentation, grinding mixes again as aggregate, economically may not be worthwhile.Chemical analysis and X-ray diffraction analysis show, in the waste and old concrete of 20 years usage periods, still have unhydrated C
2S reaches the not Ca of carbonization (OH)
2, and the aggregate material that can use according to the analysis correct decision waste and old concrete of mineralogical composition: useless common brick and blue bricks mineralogical composition behind life-time service are quite similar, the SiO that reacts during sintering
2The a large amount of existence, and a large amount of not carbonizations, the oxide compound of aquation are arranged behind the sintering, these oxide compounds can continue to bring into play cementation through after the special excitation.And building waste after levigate owing to following reason also has certain glued active: (1) is newly broken, levigate waste residue surface has higher surface energy; (2) contain a certain amount of not aquation composition in new broken, the levigate waste residue: (3) are newly broken, some have the material of lateral reactivity in the levigate waste residue, under the effect of exciting agent, show certain hydration reaction activity.Therefore essential earlier with its activation before utilizing this part material again.
The building waste pellet need be through broken, screening, and the particle diameter and the ratio of the broken back of control building waste pellet.Building waste pellet grating of the present invention is: 20～2mm accounts for 40%～60%, accounts for 60%～40% below the 2mm.
