ACI 308.1-11 PDF Download

ACI 308.1-11 is a specification for curing concrete that can be applied to any construction project by citing it in the project specification. The specification provides requirements for alternative methods for curing concrete, which may vary in effectiveness, cost, schedule impact, and other aspects of the project. The Architect/Engineer must identify the concrete elements that need to be cured and choose the appropriate method for curing those elements. The specification includes default settings that may or may not be applicable to a specific project, and checklists are provided to guide the Architect/Engineer in customizing the specification for their project. The Architect/Engineer may also allow the Contractor the option of using permissible curing methods, subject to review and approval.

It is important for the Architect/Engineer to determine whether deliberate curing efforts are to be terminated based on a predetermined time or specified concrete properties. In the case of terminating curing efforts based on concrete properties, the Architect/Engineer must also select the test method used to measure those properties. The specification specifically addresses curing methods applied after the placement of concrete and does not cover internal curing (using saturated lightweight aggregate or other materials for supplemental water) or accelerated curing (heat curing).

Lastly, the materials, processes, quality control measures, and inspections described in this specification should be performed by individuals who hold the appropriate ACI certifications or equivalent qualifications.
