ACI 306R-16 PDF Download

ACI 306R-16 is a standard It is designed to provide guidance to specifiers, contractors, and concrete producers on the selection processes for cold weather concreting methods. The main objectives of this standard are to prevent damage to concrete caused by freezing at early ages, ensure that the concrete develops the recommended strength for safe removal of forms, maintain curing conditions that promote normal strength development, limit rapid temperature changes, and provide protection consistent with the intended serviceability of the structure.

The standard emphasizes that proper proportioning, production, placement, and protection of concrete placed during cold weather are crucial for it to develop sufficient strength and durability to meet the desired service requirements.
