- Аннотация: Aqueous formulations based on anionic butadiene-styrene microspheres (BSMs) andcationic poly(diallyldimethylammonium chloride) (PDADMAC) with the weight PDADMAC fractionfrom 0 to 1 were studied as the stabilizers of loose sandy soils. In general, these systems were shown tobe represented as the mixtures of microspheres saturated with PDADMAC and unbound polycation.Mechanical testing of BSMs–PDADMAC films evidenced that with increasing weight PDADMACfraction, a 20-fold growth in elastic modulus, 2-fold growth in strength and 2-fold decrease in ultimatestrain of the material were observed. Treatment of the sand with the above formulations resulted information of a protective porous polymer-sand surface crust with the strength from 0.8 to 45.0 MPa.“Elasticity–rigidity” balance and water resistance of the crusts were controlled by weight fraction ofpolycation in the mixed formulation. Stable water-resistant polymer-sand crusts were shown to beprepared using formulations with the weight PDADMAC fraction from 0 to 0.2. The results indicateda great potential of the polymer-colloid formulations for the fabrication of structured sand coatingswith controlled properties.
