Overview

EN 1877-1:2000 is a pivotal European Standard developed by CEN, focusing on products and systems used for the protection and repair of concrete structures. This standard specifies a precise test method for determining the epoxy equivalent of epoxy compounds, which is critical in evaluating reactive functions related to epoxy resins. The method ensures consistent and reliable measurement, supporting effective quality control and material performance assessment in protective and repair applications for concrete infrastructure.

This standard is applicable to all types of epoxy compounds used in concrete repair systems, except for epoxide equivalents of nitrogen-containing resins. By standardizing the determination of epoxy equivalent, EN 1877-1 promotes uniformity and technical compatibility across products in the construction and infrastructure maintenance sectors.

Key Topics

• Epoxy Equivalent Determination: Establishes standardized methodology to quantify the epoxy equivalent in epoxy compounds.
• Scope: Applicable to epoxy compounds used in protection and repair products for concrete, excluding nitrogen-containing resins.
• Test Methods: Provides detailed steps and conditions for conducting reliable laboratory testing among manufacturers, suppliers, and quality control laboratories.
• Reactive Groups: Focuses on reactive functions in epoxy resins, critical for performance in bonding and repair applications.
• Quality Assurance: Supports robust product validation and certification of epoxy-based repair systems.

Applications

• Concrete Structure Repair: Assists manufacturers and engineers in verifying the chemical properties of epoxy resins used in structural maintenance to ensure durability and performance.
• Protection Systems: Ensures the epoxy components deliver expected reactive characteristics needed to protect concrete from environmental and mechanical damage.
• Material Development: Facilitates research and development of advanced epoxy compounds tailored for repair and protective coatings in civil engineering.
• Construction Quality Control: Used by laboratories to validate epoxy resin formulations prior to application on-site, reducing risk of repair failure.
• Infrastructure Maintenance: Helps public and private entities maintain long-term structural integrity of bridges, tunnels, and other concrete infrastructures by ensuring high-quality repair materials.
