WHAT ARE REBARS?
These are epoxy coated iron reinforcing bars. They are preferred for the reinforcement of structures, increasing service life where used. Epoxy coated rebars are manufactured as per ASTM A 775/775M standards.
WHY CHOOSE THEM?
- These play a significant role in the prevention of corrosion, which causes concrete structures to crack and lose its properties.
- Thanks to epoxy coated rebars, a physical and electrochemical barrier is created on steel, reinforcement is isolated and the occurrence of corrosion is prevented.
- Epoxy coated rebar products are much stronger in proportion to normally used products.
- These products provide almost 50% profit in the long-term compared to standard products when cost is calculated.
WHY ARE THEY COATED IN EPOXY PAINT?
When chemicals are used under various environmental and process conditions, natural factors such as rain water, humidity and other materials can come into contact with steel reinforcements within the bearings due to various reasons causing the reinforcements connecting foundation concrete, concrete platforms, concrete columns and beams to start to corrode. Epoxy coating prevents liquid from reaching rebars and as with the dowel bars, both rusting and corrosion resistance are increased. Potential cracks and fractures in the concrete is eliminated.
PLACES OF USE
They are highly used in strategic and qualified infra and superstuctures, roads, bridges, viaducts and industrial facilities, energy plants, dams, malls and high-rise buildings.
WHAT IS THE CONCRETE ADHESION STRENGTH OF EPOXY COATED STRUCTURAL IRON?
Epoxy coated rebars have a higher concrete adhesion strength capacity than uncoated rebars. A material’s elastic modulus is the measurement of its resistance to being deformed elastically under force. The most important parameter in determining this modulus is its interatomic bonding strength. The initial slope of the interatomic bonding strength curve for materials with high elastic modulus is high. The rigidity of the material is directly proportional to the interatomic bonding strength curve. The higher the initial slope of the interatomic bonding strength curve, the more rigid the material is. When the situation is the other way around, deformation is observed on the material.
The statistics for pulling tests on epoxy coated rebars are provided in the following table. The highest adhesion values belong to the epoxy coated rebar, as observed in the MPa results.
