EPOKSİ KAPLAMALI VE KAPLAMASIZ DONATILARIN MEKANİK ÖZELLİKLERİNİN KARŞILAŞTIRMALI ANALİZİ

Öz

Bu çalışma, donatı çeliğinin dış etkilere karşı korunmasını sağlamak ve beton içindeki mekanik ve aderans performansını artırmak amacıyla epoksi kaplama uygulamasını incelemektedir. Bu amaçla, 10 mm çapında ve 30 cm uzunluğundaki epoksi kaplı ve kaplamasız filizler, 15×15×15 cm boyutlarındaki beton bloklara iki farklı yöntemle yerleştirilmiştir: döküm sırasında doğrudan ve kür sonrası kimyasal dübelle sonradan ekilerek. Her numunede bir adet filiz bulunmakta olup; akma dayanımı, çekme dayanımı, kopma dayanımı, kesit daralması, kopma uzaması, tokluk, elastisite modülü ve aderans dayanımı gibi mekanik testler gerçekleştirilmiştir. Sonuçlar, epoksi kaplamanın akma ve çekme dayanımı gibi mekanik özellikleri artırdığını, tokluğu iyileştirdiğini ve yeterli süneklik sağladığını ortaya koymuştur. Rijitlikte ve plastik şekil değiştirme kapasitesinde azalma gözlenmiş olsa da, kaplama akma davranışının güvenilirliğini artırmıştır. En dikkat çekici sonuç ise aderans dayanımındaki artış olmuş, özellikle sonradan ekilen filizlerde %30’un üzerinde iyileşme sağlanmıştır. Genel olarak, epoksi kaplama, kimyasal dayanım ve uzun ömürlülüğün önemli olduğu koşullarda donatıların mekanik bütünlüğünü ve aderans performansını artıran etkili bir çözüm sunmaktadır.

COMPARATIVE ANALYSIS OF MECHANICAL PROPERTIES OF EPOXY COATED AND UNCOATED REINFORCEMENT BAR

Abstract

This study aims to enhance the mechanical and bond performance of reinforcing bars embedded in concrete by applying epoxy coatings as a protective layer against external effects. For this purpose, epoxy-coated and uncoated rebars with a diameter of 10 mm and length of 30 cm were embedded into 15×15×15 cm concrete blocks using two different methods: cast-in-place and post-installed with chemical anchoring after curing. Each specimen contained a single rebar, and mechanical tests including yield strength, tensile strength, fracture strength, reduction of area, elongation at break, toughness, modulus of elasticity, and adherence strength were conducted. The results showed that epoxy coating slightly improved mechanical properties such as yield and tensile strength, while enhancing toughness and maintaining sufficient ductility. Although a slight decrease in stiffness and plastic strain capacity was observed, the coating increased the reliability of yield behavior. Most notably, adherence strength was significantly improved by epoxy coating, particularly in post-installed specimens, where an increase of over 30% was recorded. Overall, epoxy coating proved to be an effective solution for improving both mechanical integrity and adhesion performance of reinforcing bars, especially in conditions where chemical durability and long-term performance are critical.
