混凝土养护标准规范

P2. If sections or parts of Standard Specification ACI 308.1 are edited into project specifications or any other document, they shall not be referred to as ACI standards, since the Standard Specification has been altered.

P3. Building codes set minimum requirements necessary to protect the public. This Standard Specification may stipulate requirements more restrictive than the minimum. Adjustments to the needs of a particular project shall be made by the Architect/Engineer by reviewing each of the items in the Specification Checklist and then including the Architect/Engineer's decision on each item as a mandatory requirement in the Project Specifications.

P4. These mandatory requirements designate the specific qualities, procedures, materials, and performance criteria for which alternatives are permitted or for which provisions were not made in the Standard Specification. Exceptions to

the Standard Specification shall be made in the Project Specifications, if required.

P5. A statement such as the following will serve to make Standard Specification ACI 308.1 a part of the Project Specifications:

Work on (Project Title) shall conform to all requirements of ACI (Standard Specification number with date suffix and title) published by the American Concrete Institute, Farmington Hills, Michigan, except as modified by the requirements of these Contract Documents.

P6. The Standard Specification Checklists identify Architect/Engineer choices and alternatives. The checklists identify the sections, parts, and articles of the Standard Specification and the action required by the Architect/Engineer.

The specification is written to allow each method of curing to be a stand-alone specification. The specifier is to determine the desired results of the curing and select the appropriate section or sections to achieve those results. Section 1 shall be included with the selected sections. The specifier is to use ACI 308-92 Standard Practice for Curing Concrete as commentary for making decisions within the checklists. The alternative methods described in each section of this Standard Specification are not necessarily equal in effectiveness, cost, effect on project schedule, or impact on other aspects of the project. To use this specification, the Architect/Engineer must not only include this document by reference in the Project Specifications, but must also review and respond to the checklists. It is imperative that the Architect/Engineer

customize this specification to meet the project requirements through the checklists. The Architect/Engineer must identify the concrete elements that are to be cured, and must choose the method to be used to cure them. Further, the Architect/Engineer must determine whether deliberate curing efforts must or may terminate after a predetermined time has elapsed, or only after particular levels of concrete properties have developed. When deliberate efforts to cure the concrete are to be terminated only when particular concrete properties have developed, the Architect/Engineer must also select the test method used to measure those properties. Checklists are provided in this document to guide the Architect/Engineer through these selection processes, and the selections must be included in the Project Specifications.
