Abstract:

This paper used butyl acrylate (BA), acrylic acid (AA), and water glass as main raw materials, and sodium dodecyl sulfate (SDS) and polyoxyethylene alkylphenol (OP-10) as composite emulsifiers, composite soil curing agent (PBA) was synthesized through pre-emulsification and semi-continuous seed emulsion polymerization. The effects of water glass modulus, curing agent content, and water-soil ratio on the unconfined compressive strength of the PBA-cured soil were investigated through orthogonal experiments. FT-IR analysis indicates that all three monomers, BA, AA, and water glass, participate in the reaction. When the modulus of water glass is 2.2, the content of curing agent is 4%(mass fraction), and the water-soil ratio is 0.44, the performance of the PBA-cured soil is optimal, with a fluidity of 132 mm and an unconfined compressive strength of 1.37 MPa after 7 d.

Key words: polyacrylate, emulsion polymerization, soil curing agent, solidified soil, unconfined compressive strength, optimal content
