Effect of Straw Fiber Modification on Performance of Gypsum Composite
Straw fibers were modified by acrylic acid coating treatment, and mechanical properties of straw fibers reinforced gypsum composite were investigated. Wax emulsion was added in order to improve waterproof properties of gypsum composite. Surface modification effect of straw fibers and micro-morphology of gypsum composite were analyzed by scanning electron microscope, infrared spectrometer and mercury porosimeter. The mechanism of modified straw fibers and wax emulsion in improving performances of gypsum composite was discussed.
