Embodiment 1
[0015] Take 1 part of acrylic acid and 1.1 parts of 30% sodium hydroxide by mass and mix them. Add 25 parts of allyl polyoxyethylene ether, 1.5 parts of methacrylic acid, 2 parts of maleic anhydride, and 12.5 parts of vinyl acetate to the acrylic acid solution in sequence, add 60 parts of water, stir and mix, and Nitrogen was passed through the mixed solution for 30 minutes, and 5 parts of γ-glycidyl etheroxypropyl trimethoxysilane (KH560) and 0.7 parts of ammonium persulfate were added dropwise at 60°C, and reacted for 6 hours to obtain a road soil stabilizer. Weigh a certain amount of air-dried soil, add cement and mix well, and the amount of cement added accounts for 5% of the mass of dry soil particles. Dilute the soil stabilizer with water, pour it into the above soil, mix well, make a ?50mm×50mm cylinder test piece, and make 3 parallel ones. The added amount of soil stabilizer accounts for 5‰ of dry soil particles, and the added amount of water accounts for 12% of the w...
Embodiment 2
[0017] Mix 1 part of acrylic acid with 2.0 parts of 10% sodium hydroxide. Add 27 parts of allyl polyoxyethylene ether, 1.5 parts of methacrylic acid, 2 parts of maleic anhydride, and 15 parts of vinyl acetate to the acrylic acid solution in sequence, add 53 parts of water, stir and mix, and Nitrogen was passed through the mixed solution for 30 minutes, and 7 parts of γ-methacryloxypropyltrimethoxysilane and 0.8 parts of ammonium persulfate were added dropwise at 65° C., and reacted for 7 hours to obtain a road soil stabilizer. Weigh a certain amount of air-dried soil, add cement and mix well, and the amount of cement added accounts for 5% of the mass of dry soil particles. Dilute the soil stabilizer with water, pour it into the above soil, mix well, make a ?50mm×50mm cylinder test piece, and make 3 parallel samples. The added amount of soil stabilizer accounts for 5‰ of dry soil particles, and the added amount of water accounts for 12.5% of the weight of dry soil particles....
Embodiment 3
[0019] Take 1 part of acrylic acid and 1.1 parts of 30% sodium hydroxide by mass and mix them. Add 22 parts of allyl polyoxyethylene ether, 1.5 parts of methacrylic acid, 2.1 parts of maleic anhydride, and 10 parts of vinyl acetate to the acrylic acid solution in sequence, add 50 parts of water, stir and mix, and Nitrogen was passed through the mixed solution for 30 minutes, and 4 parts of 3-aminopropyltriethoxysilane and 0.8 parts of ammonium persulfate were added dropwise at 55° C., and reacted for 8 hours to obtain a road soil stabilizer. Weigh a certain amount of air-dried soil, add cement and mix well, and the amount of cement added accounts for 6% of the mass of dry soil particles. Dilute the soil stabilizer with water, pour it into the above soil, mix well, make a ?50mm×50mm cylinder test piece, and make 3 parallel samples. The added amount of soil stabilizer accounts for 2‰ of dry soil particles, and the added amount of water accounts for 12.5% of the weight of dry ...
