Mechanical property test of polyvinyl alcohol (pva) fiber reinforced concrete

The traditional PVA-ECC mix proportion is improved based on the orthogonal test to obtain the PVA fiber concrete material with lesser fiber content and conventional aggregate size satisfying structure use requirements and lower construction cost requirements. Moreover, material property test of this material is conducted, and the failure mode of the test piece and the influence factors are analyzed. Then the rupture strength, compressive strength and the respective load-deformation curves are obtained, and a basis for numerical simulation is provided.
