Overview
EN 12615:1999 is a European Standard developed by CEN that specifies a test method for determining the slant shear strength of concrete bonds. This standard focuses on assessing the structural bond strength between two concrete substrates, which is critical when evaluating the integrity of repaired or protected concrete structures. The method can be applied to various combinations including hardened concrete bonded to hardened concrete, as well as fresh concrete bonded to hardened concrete. The test accommodates both dry and wet conditions of the hardened concrete substrates, making it versatile for diverse现场 applications.
Key Topics
- Test Methodology: EN 12615:1999 outlines the detailed procedure to measure the slant shear bond strength, which is essential for determining the durability and load-bearing capacity of bonded concrete layers.
- Concrete Combinations: The standard covers bond strength evaluation for:
- Hardened concrete bonded to hardened concrete
- Fresh concrete bonded to hardened concrete
- Environmental Conditions: The test method is adaptable to substrates in either dry or wet states, reflecting realistic site conditions during repair or protection works.
- Structural Bond Assessment: This standard provides a reliable way to quantify the mechanical strength at the interface between two concrete elements, which is a critical factor in the longevity of concrete repairs.
Applications
EN 12615:1999 is widely used in the construction and civil engineering industries to:
- Evaluate Repair Products: Assessing the performance of repair mortars and bonding agents intended to restore concrete structures.
- Quality Control: Ensuring the bonding compatibility between new and existing concrete during structural rehabilitation projects.
- Research and Development: Supporting the innovation of products designed for concrete protection and repair by providing consistent and reproducible bond strength data.
- Structural Safety: Verifying adequate bond strength to maintain structural integrity and prevent delamination or failure at joints and repairs.
