Mechanical and microstructural properties of recycling granite residual soil reinforced with glass fiber and liquid-modified polyvinyl alcohol polymer.

Glass fiber and liquid-modified polyvinyl alcohol polymer (SH Polymer) are used to reinforce granite residual soil. In this paper, scanning electron microscopy (SEM) tests and drop-weight tests were used to study the microscopic interaction mechanism and impact resistance of granite residual soil specimens reinforced by glass fiber and SH Polymer. Combined with the equivalent confining pressure theory, Mohr-Coulomb intensity lines were used to quantitatively analyze the reinforcement effect of glass fiber.
