Abstract:
This month’s Q&A is a follow up to the February 2025 Q&A. It discusses changes in core conditioning requirements in ACI CODE-318 and ASTMC42/C42M that took place within the last 25 years and research findings that led to these changes. It also explains whether standard moisture conditioning requirements could be changed on some projects.
