Description
Technical field
The present invention relates to a kind of industrial caustic, the invention particularly relates to the application process of a kind of industrial caustic in road foundation, base treatment.
Background technology
Alkaline residue is that alkali factory utilizes ammonia-soda process to produce soda ash and the white solid waste material that produces, China produces soda ash and adopts ammonia-soda process more at present, its output accounts for more than 60% of soda ash total output, thereby produced a large amount of alkaline residues, the stacking of these waste residues takies a large amount of soils, while alkaline residue dust is to diffusion all around, and is very big to surrounding environment influence.Large-scale alkaline residue will bring the huge social environmental issue, storage need take a large amount of soils, the discarded resource of both having wasted, contaminated environment again, recycle this regenerated resources and caused the great attention of the Chinese government, both at home and abroad to the processing of alkaline residue with turn waste into wealth and carried out many-sided further investigation.
At present, the alkaline residue utilization is more in the research of building engineering field.The institute of civil engineering, Ukraine Kiev has at first succeeded in developing the alkaline residue concrete, obtains high evaluation and extensive use (Dong Jindao, alkaline residue cementitious materials and alkaline residue concrete, concrete, 1999 the 2nd phase P41～48); Tianjin Municipal Architecture Design and Research Institute and Tianjin mechanical execution company just utilize alkaline residue to replace loess to carry out experimental study as packing jointly, and carried out large-area applications at sky, Tanggu alkali dormitory, obtained better effects, it is primary raw material that Tianjin New Building Materials industrial group and Jiaozhuo chemical industry three factories have developed jointly with the alkaline residue, be equipped with the generation method of a small amount of flyash and sulfate low-temperature sintering cement, be called alkaline residue building cementing material (Hou Jinfang " research that alkaline residue replaces engineering soil to fill out pad " University Of Tianjin Master's thesis P2～3 in 2004); Green building material technical research institute of Southeast China University has carried out the research of alkaline residue modified bitumen mixed fillers, good effect (Qian Chunxiang etc. " alkaline residue is as the feasibility study of bituminous mixture filler " have been obtained, highway communication science and technology, 2006 23 volume the 4th phase P14～18).Gather Chinese scholars the twice laid achievement in research of alkaline residue is mainly contained the following aspects: flyash-alkaline residue brick, the high strong type haydite of alkaline residue-flyash, alkaline residue concrete, alkaline residue are filled out (Wang Yanyan etc. such as pad engineering soil, alkaline residue mixed cement, alkaline residue modified bitumen mixed fillers, the development of comprehensive utilization situation research of alkaline residue, industry security and environmental protection, 2005 31 volume the 2nd phase P29～31).Because the water stability of alkaline residue own is poor, intensity is low, and high-grade highway and town road are very high to the performance requirement of filling material, alkaline residue is only limited to as filling out the pad engineering soil in the highway construction Application for Field and fills out the low-lying location of pad inferior grade road process so far, and be not applied in high-grade highway and the town road, as the filling material of roadbed processing, subbase and basic unit is domestic precedent do not arranged.

In urban roadbed is handled, traditional fado of doing adopts the weak soil that road materialss such as rubble, lime and flyash are too high to water content, organic content is abundant to be cured processing, reach designing requirement to seek roadbed intensity, this often needs higher expense.Many in recent years urban road surfaces occur " when annual overhaul, the coming year bad " phenomenon, being unequal to ideal with the roadbed treatment effect has great relation, the maintenance expense that this has not only increased road has greatly also caused unnecessary economic loss to administrative department.
For highway and speedway, though be fill subgrade, roadbed filling does not often reach code requirement, needs to solidify to handle, and the demand of cement, lime and flyash is very big.Along with the fast development of traffic engineering in recent years, because express highway roadbed processing (end of the bridge or highway section, pond) needs a large amount of rubbles and cement, building stones seem and more and more lack, and expense is higher and be difficult to produce a desired effect; On the other hand, roadbed filling adopts in an opposite direction ash to handle, and makes that the demand of lime is huge, and this not only causes the rise in price of lime, and bum lime is also seized the opportunity and sneaked into use; And the deficient and transportation difficulty of flyash the increasing substantially of cost that more caused building the road in the base material, the utmost point need be sought alternative material and treatment measures.
Alkaline residue is as industrial residue, contaminated environment, and (utilization is established in Tianjin Caustic Soda Plant of nineteen twenty-three to land occupation, is China alkali factory the earliest, the annual alkaline residue 1.8 * 10 of discharging
5T has formed the alkaline residue mountain between Tanggu District and development zone, the about 3.5km of floor space
2).The existence of alkaline residue makes the soil property around the place be subjected to saliferous erosion, while alkaline residue dust is to diffusion all around, and is very big to the urban environmental impact, and alkaline residue takies a large amount of soils, not only influence the ecoscape in area, and influence and hinder exploitation, construction and the economic development in this city.
