Problems solved by technology

[0004] With the rapid development of society, due to limited natural resources in engineering construction, the existing sand and gravel materials are far from meeting the growing needs of engineering construction. At the same time, the mining of sand and gravel has also caused serious damage to the natural environment, and a large amount of resources have been invested And the waste is serious, the ecology is constantly being severely damaged, the quality of the social living environment is declining, the rapid growth of engineering construction has made the whole society pay too much, and a large amount of urban construction waste is produced every day

Embodiment

[0018] 1. According to 37% of glycerin, 24% of sulfonated oil, 13% of sodium sulfate, 12% of sulfuric anhydride, 7% of anionic cellulose, and 7% of water glass, mix uniformly under the environment of 60 ℃.

[0019] 2. Dilute the prepared soil solidifying agent 200 times with drinking water.

[0020] 3. Choose 96kg of construction waste, fully pulverize into fine aggregates with a maximum particle size (diameter) of about 3mm, add 4kg of P042.5 cement and 2.8kg of soil solidifying agent diluted 200 times according to the above step 2.

[0021] 4. Stir evenly and pave the road after a certain mechanical load.

[0022] 5. The current road standard is: seven-day unconfined compressive strength, the national standard: greater than 3Mpa, the test result is: seven-day unconfined compressive strength, the result is 3.7Mpa.

Abstract

The invention discloses a preparation and use method for soil curing agent, and particularly relates to the soil curing agent used for curing soil and processing urban construction rubbishes, heavy metal contaminated soils and the like. The soil curing agent mainly consists of the following ingredients in parts by weight: 30-39% of glycerol, 19-27% of sulfonated oil, 9-20% of excitant, 8-15% of oxidizing agent, 3-12% of dispersant and 4-12% of sodium silicate, wherein the excitant consists of one or a plurality of sodium sulfate, sodium chloride and magnesium chloride, and the oxidizing agent consists of one or a plurality of sulfuric anhydride, potassium permanganate, potassium chlorate and ferric chloride, and the dispersant is one or a plurality of metal soap classes, paraffin and anionic cellulose.

Description

[0001] 【Technical field】 [0002] The invention designs a method for preparing and using a soil solidifying agent, in particular a soil solidifying agent used for solidifying soil, resource disposal of urban construction waste, heavy metal polluted soil, etc., and belongs to the field of fine chemistry. [0003] 【Background technique】 [0004] With the rapid development of society, due to limited natural resources in engineering construction, the existing sand and gravel materials are far from meeting the growing needs of engineering construction. At the same time, the mining of sand and gravel has also caused serious damage to the natural environment, and a large amount of resources have been invested And the waste is serious, the ecology is constantly being seriously damaged, the quality of the social living environment is declining, the rapid growth of engineering construction has made the whole society pay a too high price, and a large amount of urban construction waste is p...
