example 1

[0025]Weigh 1.0kg of river bottom mud and put it in the sun to dry naturally for 1 day to obtain river bottom mud with a moisture content of 1%, then weigh 0.8kg of dried hawthorn and put it into 80mL of sodium hydroxide solution with a mass fraction of 5%, heat to boil Treat for 80 minutes, after the temperature drops to 70°C, add 100mL of hydrogen peroxide with a mass fraction of 30%, continue heating for 35 minutes, keep the temperature at 70°C, filter, separate the filter residue, wash the filter residue with deionized water until neutral , put it in an oven, dry it at 50°C for 1 hour, and then discharge the fiber sample. Weigh 30g of polypropylene and heat it up to 160°C to soften it. Add 60g of fiber sample and 5g of titanic acid to the softened polypropylene. The ester coupling agent PN-105 was mixed and ground for 10 minutes. After grinding, the self-made modified fiber was obtained. Continue to mix and stir the ordinary Portland cement and the silane coupling agent KH-...

[0027] Weigh 1.5kg of river bottom mud and put it in the sun to dry naturally for 1 day to obtain river bottom mud with a moisture content of 2%, then weigh 0.9kg of dried hawthorn and put it into 100mL of sodium hydroxide solution with a mass fraction of 5%, heat to boil Treat for 90 minutes, after the temperature drops to 75°C, add 125mL of hydrogen peroxide with a mass fraction of 30%, continue heating for 40 minutes, keep the temperature at 75°C, filter, separate the filter residue, wash the filter residue with deionized water until neutral , put it in an oven, dry at 55°C for 1.5h, and the output is a fiber sample. Weigh 40g of polypropylene and heat it up to 165°C to soften it. Add 75g of fiber sample and 7g of titanium to the softened polypropylene. Ester coupling agent PN-105 was mixed and ground for 11 minutes. After grinding, the self-made modified fiber was obtained. Continue to mix and stir ordinary Portland cement and silane coupling agent KH-550 for 9 minutes to o...

Abstract

The invention discloses a high-strength durable type solidified soil preparation method and belongs to the technical field of civil engineering preparation. According to the preparation method, polypropylene resin and a titanate coupling agent are utilized to modify plant fiber to form a covalent bond, the covalent bond is utilized to modify cement powder, a silane coupling agent is added to be mixed and stirred and is blended with vegetable oil and sludge to be fermented, microorganisms in the sludge are utilized to decompose the vegetable oil to generate a lipophilic ester group, the ester group is grafted to the surface of the cement powder, the cement powder can serve as an interface bonding catalyst after being modified, pores in solidified soil can be filled by the particles, and modified natural rubber, quartz sand, coal ash and silica fume are added to fill the pores, strength and durability of the solidified soil are improved; finally, a mixed salt solution is added to generate gel, and the porosity of the solidified soil is reduced; thus, the strength and the durability of the solidified soil are improved, sand is doped into a mixture to change grain composition of the solidified soil, a coarse particle content of the solidified soil is improved, a framework effect is enhanced, and the strength and the durability of the solidified soil are further improved.

Description

technical field [0001] The invention discloses a preparation method of high-strength durable solidified soil, which belongs to the technical field of civil engineering preparation. Background technique [0002] Consolidated soil is a road surface formed by adding a certain stabilizer to the soil to stabilize the soil, and then paving and rolling. Solidified soil is a new natural solidified soil pavement system formed by stabilizing natural sand, ore tailings, slag waste soil and other renewable raw materials through scientific proportioning and technical treatment. [0003] Like air and water, roads and pedestrian spaces are used unconsciously every day. Yet roads and pedestrian spaces are fundamental to our daily life and economic activity. It refers not only to the movement of cars and people, but also places for encounters and leisure, the formation of urban landscapes, etc. The pavement pavement that has been laid has satisfied and enriched people's daily life, but th...
