Where can you find in ACI code the effect of cold joints in concrete?

The effects of cold joints in concrete are addressed in the ACI (American Concrete Institute) code, specifically in ACI 318, which covers building code requirements for structural concrete. In particular, Section 10 discusses the design considerations for joints, including cold joints, and their impact on structural integrity. Additionally, ACI 224 provides guidance on controlling cracking, which can also relate to cold joint conditions. For detailed analysis and recommendations, refer to these sections in conjunction with relevant design and construction practices.
