Influence of POM fibers modified by nano-SiO2 on mechanical strength of cement-based materials

As a reinforcing material for cement-based composites, the smooth surface and lack of chemical activity of polyoxymethylene (POM) fiber result in poor adhesion to the matrix, thereby limiting the application effect. In this paper, an attempt to improve the bonding performance between the POM fibers and the matrix has been made by increasing the fiber surface roughness and surface activity with nano-SiO2 (NS) modification. The effects of NS (0~10%) modified POM fibers on the flexural and compressive strengths, bending toughness and tensile strength of mortars were studied. The deposition effect of NS on the surface of the fiber and the microstructure of the bonding interface between the fiber and the cement matrix were characterized by SEM and EDS. Results show that NS was successfully deposited on the surface of POM fiber, which greatly improved the mechanical properties of POM fibers reinforced cementing materials. To be specific, the enhancement effect on flexural strength was most obvious when the mass fraction of NS was 5% of the POM fibers to be modified, which were 16.9% and 16.4% at 7 and 28 d higher than that of the control sample, respectively; the bending toughness coefficient reached the maximum value when the mass fraction of NS was 2.5%, which was 57.9% at 28 d higher than that of the control sample; and the tensile strength reached its maximum when the mass fraction of NS was 7.5%, which was 57.2% at 28 d higher than that of the control sample.

1 Introduction

In recent years, fiber-reinforced cement-based composites (FRC) have developed rapidly. POM fibers are a type of synthetic fiber used in FRC due to their high strength, excellent abrasion resistance, as well as outstanding pull-out recovery performance. As a reinforcing
