ACI 440.9R-15 PDF Download

ACI 440.9R-15 is a guide that provides guidance on assessing the durability performance of internal and external Fiber-Reinforced Polymer (FRP) composite reinforcement using accelerated conditioning protocols (ACPs) in combination with standard test methods for mechanical properties. The primary purpose of ACPs is to allow manufacturers to characterize the durability of their FRP composite products and to encourage researchers and testing laboratories to adopt common test protocols.

It is important to note that the results obtained from the tests conducted using the recommended ACPs should not be used in the design of FRP composites as concrete reinforcement. However, as more research is conducted and a better understanding of the relationship between field performance and ACPs is established, these protocols may be refined for use in quality control and design processes. By establishing consistent and standardized testing procedures, a meaningful database of durability testing of FRP materials can be developed, which will contribute to the improved performance of FRP composites as a sustainable and durable reinforcement system for concrete.
