STUDY ON THE MICROSTRUCTURE OF PLANT FIBER REINFORCED GYPSUM COMPOSITES

The influences of adding addition agent, such as slag and cement, on the microstructure and properties of gypsum composites were investigated by means of SEM analyses. The results show that treating the surface of plant fiber with styrene-acrylic acid latex can improve effectively the fiber-matrix interface binding state of plant fiber gypsum composites, and a remarkable increase in its mechanical properties can be obtained.
