ACI 364.5T-10 PDF Download

ACI 364.5T-10 is a specific standard within the ACI (American Concrete Institute) that focuses on the "Importance of Modulus of Elasticity in Surface Repair Materials." This standard is part of the TechNotes series, which are committee documents that provide practice-oriented guidance on specific topics.

The purpose of ACI 364.5T-10 is to highlight the significance of the modulus of elasticity in surface repair materials for concrete structures. The modulus of elasticity is a measure of a material's stiffness and its ability to deform under stress. In the context of surface repair materials, it is crucial to consider the modulus of elasticity to ensure proper compatibility and durability.

This standard outlines the factors that influence the modulus of elasticity of surface repair materials and provides guidance on selecting materials with suitable modulus of elasticity values. It emphasizes that the modulus of elasticity should be compatible with the substrate concrete to avoid issues such as differential movement or premature failure. Proper assessment and understanding of the modulus of elasticity is essential for effective repairs and long-term performance of concrete structures.
