Effect of Perlite Addition on Fracture Properties of Discontinuous Fiber-Reinforced Cementitious Composites Manufactured Extrusion Molding

We investigated the effect of perlite addition on poly vinyl alcohol (PVA) reinforced cemen- titious composites manufactured by extrusion molding. The PVA fiber composites of Perlite/C=10% and W/C=80% produced pseudo strain-hardening behavior with multiple cracking, and their ultimate tensile strain…

Abstract

We investigated the effect of perlite addition on poly vinyl alcohol (PVA) reinforced cemen- titious composites manufactured by extrusion molding. The PVA fiber composites of Perlite/C=10% and W/C=80% produced pseudo strain-hardening behavior with multiple cracking, and their ultimate tensile strain of this PVA fiber composite reached 2.2%. It was demonstrated that multiple cracks in the composite became invisible on naked eyes, possibly due to the matrix microstructure modified by the addition of per- lite.
