This technical note briefly discusses non-destructive evaluation of cold joints in concrete structures. We will review how structural engineers and quality control laboratories can utilize NDT methods to assess the quality and integrity of concrete on or around the cold joint. How Does GPR Work? GPR technology utilises electromagnetic radiation to detect and image. The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete. While often dismissed as purely aesthetic blemishes, a cold joint is, fundamentally, a failure of integration—a plane of weakness that interrupts the essential structural continuity in columns that is vital for resisting bending, shear, and axial compression. If not handled correctly, it can weaken structures and shorten their lifespan.

Cold aisle containment (CAC) works like this: instead of chasing heat, you trap cold air right where it's needed — at the front of the racks. You build barriers around the aisle, then feed it conditioned air from the raised floor or ducted units. Proper server rack cooling is essential to prevent overheating, improve performance, and extend equipment lifespan. In this guide, we'll break down how hot aisle and cold aisle configurations. The hot aisle /cold aisle data center layout was originated by IBM in 1992 and it is one of the oldest ways to save energy in the data center. 1 Hot aisle/cold aisle layout involves lining up server racks in alternating rows with cold air intakes – the fronts of servers – facing each other (the. The system simply aligns server fronts (air intakes) toward a shared cold aisle, and backs (exhausts) toward a shared hot aisle.
