This subject was approved in March 2000 and was appraised by the Science and Technology Department of Hebei Province. This system studies the regularity of the strengthening and toughening of cement-based materials by synthetic fibers with different chemical properties and mechanical properties, the regularity of grafting of synthetic fibers and polymer films, and the chemical and topographical changes in the surface properties of fibers on cement-based materials. Improve the effect of toughening effects. Use of grafting reaction to make fiber reinforced cement substrate
