Development of Cement Based Composites with PVA Fibers

摘要

This paper is focused on mechanical properties of fine-grained cement based composite materials reinforced by short PVA fibers. Cementitious materials are characterized by their fragile matrix. A reinforcing by fibers (e.g. steel fibers, PVA fibers, PP fibers, glass fibers) increases tensile strength. The behavior of the elements after developing and spreading of micro cracks under load should be described as a strain-softening, strain-hardening, etc. The multiple cracking under load is typical deformations of composite materials reinforced by short PVA fibers, that is known worldwide as a ECC.
