Abstract

This study aims to evaluate the improvements in mechanical properties of Portland cement concrete reinforced with Polyvinyl Alcohol (PVA) fibers, specifically focusing on compressive strength, workability, and flexural strength, compared to conventional concrete. The use of fibers in airport concrete pavements has been widely recognized for improving various mechanical properties, yet research on PVA fibers remains limited. To address this gap, an experimental program was conducted using PVA fiber contents of 0,5% and 1,0% by volume, compared to plain concrete, encompassing material characterization, mixing, molding, curing, and testing. Results indicated a significant reduction in workability with increased fiber content, necessitating the use of superplasticizers to maintain desired consistency. Compressive strength results were inconsistent, with the 0,5% fiber content showing the highest improvement in strength, while the 1,0% fiber content showed a less significant improvement in this aspect. It was not possible to definitively confirm a change in compressive strength with the addition of PVA fibers. In contrast, flexural strength tests showed no significant difference between plain concrete and PVA fiber-reinforced concrete. This may be attributed to the anchorage of fibers in the cementitious matrix, suggesting the need for further pullout tests to better understand the anchorage mechanisms. The findings of this study contribute to the understanding of PVA fiber-reinforced concrete, offering practical insights for optimizing concrete mixes for enhanced performance in construction applications.
