Description
Technical field
The present invention relates to a kind of canal system earth solidification agent, especially require and the compound novel architecture soil-solidified-agent of a kind of organic and inorganic material of invention and the production method of this curing compound at canal system engineering high strength, high impervious, high anti-freezing, high-durability etc.
Background technology
Some developed countries are building in the engineerings such as road, harbour, airport from 20 beginnings of the century, since employing lime, cement are improved soil, have obtained good effect.The seventies in 20th century; countries such as U.S., day, moral have carried out profound exploitation to the reclamation technology; technical level obtains rapid progress; by original single lime, cement, flyash etc.; develop into being used for new material---the soil-solidified-agent of consolidated soil specially, be widely used in every field such as road, civil construction, environmental protection, farmland water conservancy works at present abroad.The present soil solidification technology of China is in the level of external twentieth century six the seventies substantially, mainly continues to use single lime, cement, flyash etc. as mix.
Soil-solidified-agent is a kind of special engineered material that can be used for solidifying all kinds soil, the physicochemical properties of the soil of Jia Guing as required, mix a certain amount of curing compound, through machinery or manually mix and stir, compaction treatment, can reach the performance indications that need, thereby abundant soil resource is modified to the engineering material of function admirable.Soil-solidified-agent is a kind of extraordinary constructional materials that is different from lime, cement, and it is compared with lime, is a kind of hydraulic cementing materials, also can make soil solidification under high water state; Compare with cement, it can not only solidify general earth, can also solidify peracid, high-alkali, high salt soil, can solve cementitious material more insurmountable specific questions when soil fixation such as cement, lime, performance than cement solidification soil is more good, has unique solidification effect and practicality widely.Hydraulic engineering and environmental engineering such as can be used for rivers and lakes burrock bank protection, bank protection, storage reservoir pond engineering, water delivery engineering, treatment of soft foundation, sludge solidification, reclaim land from the sea.Have good resistance to compression, impervious, anti-freezing property after the curing soil moulding, construction costs is low, easy construction, advantage such as elegant in appearance.
Summary of the invention
Present soil-solidified-agent intensity both domestic and external lower (unconfined compression strength was generally about 2-3MPa, about China Higher level road base layer requirement of strength 4MPa in 7 days) generally is used for road base layer construction and riverway sludge more and solidifies.Because soil solidification body antiseepage poor ability possesses frost resistance hardly, does not reach the requirement of channel to materials ' durability, therefore, seldom be used for the canal system construction.We are by new material, new technologies such as high-performance dispersing agent, multi-element composite materials, develop have high strength, canal system earth solidification agent (the curing compound kind that special optimization is arranged at different types of soil of high permeability resistant, high frost resistance, thereby form the product of a seriation), adopt the unconfined compression strength of the firming body of this series curing compound moulding can reach more than the 15MPa, transmission coefficient is less than 10-8cm/s, freezing-thawing cycles reaches more than 50 times, makes the performance indications of soil-solidified-agent step up a new step.
This canal system earth solidification agent is mainly by 44%～60% calcium silicates, 8%～19% calcium aluminate, 3%～14% anhydrous calcium sulphoaluminate, 1%～16% sulfate, 2%～14% calcium hydroxide, 0%～3% NaOH, and 0.01%～0.09% naphthaldehyde condensation compound, 0.01%～0.06% lignin sulfonate, 0%～0.0008% modified abietic resin are formed.At different soil types, soil property composition, performance requirement, each raw material consumption changes in above-mentioned scope, thereby forms a series of curing compound product.
For example the configuration proportion of clay class curing compound is: 48～54% calcium silicates, 8～14% calcium aluminate, 5～8% anhydrous calcium sulphoaluminate, 10～16% calcium sulfate, 1～5% aluminum sulfate, 2～6% calcium hydroxide, 1～3% NaOH, and 0.06～0.09% naphthaldehyde condensation compound, 0.01～0.04% lignin sulfonate, 0.0005～0.0008% modified abietic resin.
For example the configuration proportion of sand soil solidifying agent is: 44～48% calcium silicates, 13～16% calcium aluminate, 10～14% anhydrous calcium sulphoaluminate, 15～20% calcium sulfate, 10～14% calcium hydroxide, and 0.01～0.03% naphthaldehyde condensation compound, 0.03～0.06% lignin sulfonate.
For example the configuration proportion of sand class curing compound is: 55～60% calcium silicates, 15～19% calcium aluminate, 3～7% anhydrous calcium sulphoaluminate, 10～16% calcium sulfate, 3～7% calcium hydroxide, and 0.01～0.03% naphthaldehyde condensation compound, 0.02～0.05% lignin sulfonate, 0.0001～0.0003% modified abietic resin.
The mode of production of this canal system earth solidification agent mainly contains: 1. mix in proportion with the natural or industrial chemicals that contains above-mentioned mineral, with the Cement Production explained hereafter, become product through calcining, grinding; 2. directly mix with the raw material of the certain fineness that contains above-mentioned mineral and make.Fineness requirement of the present invention is generally 250～300m2/kg, and keeping life is half a year.
In view of the difference of the mode of production, wherein:
Calcium silicates, calcium aluminate, anhydrous calcium sulphoaluminate, calcium hydroxide, NaOH can also can get by the mixture of calcined clay, limestone, alumina, gypsum, alunite by getting in portland cement, Portland cement, aluminate cement, the sulphate aluminium cement;
Sulfate can adopt chemical products calcium sulfate, aluminum sulfate, sodium sulphate etc., also can get by grinding or the calcining plaster of paris, alunite etc.;
Calcium hydroxide also can directly adopt fine grinding quicklime, and NaOH also can directly adopt industrial chemicals;
Naphthaldehyde condensation compound can adopt commercially available naphthaldehyde condensation compound class cement water reducing agent;
Lignin sulfonate can utilize the papermaking enterprise waste liquid to process;
Modified rosin resin can use commercially available industrial goods;
Canal system earth solidification agent raw material of the present invention is easy to get, and can select different proportion schemes according to different user, different location, different soil property, different weather and geographical conditions, and adopts reasonable construction scheme, thereby improves workmanship, reduces engineering cost.
This canal system earth solidification agent can be widely used in engineering foundations such as reservoir, channel, pond, dam and handle and bank protection; The sludge solidification processing in pond, river course, lake, reclamation, php slurry are handled; Fix the sand to build the road in the roadbed of speedway, high-grade highway, country road and basic unit, railway bed, desert, the engineerings such as floor treatment of airfield runway basis, stadiums; The weak ground of various building lot processing, weakness and ultra-soft is handled, the sewer pipe based process; The aspects such as ground processing in harbour, harbour and rubbish stockyard.
