Modification of Polypropylene Fibers by Acrylic Acid and its Influence on the Mechanical Property of Cement Mortar

Abstract:

Article Preview

The surface of the PP fibers were modified by acrylic acid and grafted by suspension in water medium. The effect of modified PP fibers on mechanical properties of cement mortar was studied. The microstructure of fibers surface, the active functional groups of fibers and the profile of cracked samples were analyzed by SEM and IR. The results show that, crylic acid was grafted on surface of PP fibers after modification; the flexural strength of cement mortar reinforced by modified PP fibers improved markedly, compared with cement mortar reinforced by ordinary PP fibers.
