13、ble to any construction project by citing it in the ProjectSpecification. The Architect/Engineer uses and supplements the provisions ofthis reference specification as needed by designating or specifying individualproject requirements to which provisions of this specification apply.This document prov
14、ides requirements for alternative methods for curingconcrete. These alternative methods are not necessarily equal ineffectiveness, cost, effect on project schedule, or impact on other aspectsof the project. To use this specification, the Architect/Engineer must notonly include this document by refer
15、ence in the Project Specification, butmust also identify the concrete elements that are to be cured, and mustchoose the method to cure those elements. This specification has defaultsettings that may or may not be applicable to a specific project. TheArchitect/Engineer is to use the Checklists includ
16、ed in this specification tocustomize the specification to a specific project. Checklists are provided inthis document to guide the Architect/Engineer through these selectionprocesses, and the selections must be included in the Project Specification.Alternatively, the Architect/Engineer may allow the
17、 Contractor the optionof using one or more of a number of permissible curing methods, subject toreview and approval. Further, the Architect/Engineer must determinewhether deliberate curing efforts are to be terminated after a predeterminedtime has elapsed, or only after specified concrete properties
18、 have developed.When deliberate efforts to cure the concrete are to be terminated only whenspecified concrete properties have developed, the Architect/Engineer mustalso select the test method used to measure those properties.This specification addresses curing methods applied after placement ofconcr
19、ete and does not apply to internal curing (use of saturated light-weight aggregate or other materials to provide supplemental water) or toaccelerated curing (heat curing).The materials, processes, quality control measures, and inspectionsdescribed in this document should be tested, monitored, or per
20、formed asapplicable only by individuals holding the appropriate ACI certificationsor equivalent.Keywords: cold-weather concreting; concrete construction; curing; curingfilms and sheets; hot-weather concreting; insulating concrete; insulation;membrane curing compounds; moist curing; moisture retentio

ACI Specification 308.1M may be referenced bythe Specifier in the Project Specification for any buildingproject, together
22、 with supplementary requirements for thespecific project. Responsibilities for project participants must bedefined in the Project Specification. ACI Specification 308.1Mcannot and does not address responsibilities for anyproject participant other than the Contractor.F3. Checklists do not form a part
23、 of ACI Specification 308.1M.Checklists assist the Specifier in selecting and specifying projectrequirements in the Project Specification.F4. The Mandatory Requirements Checklist indicateswork requirements regarding specific qualities, procedures,materials, and performance criteria that are not defi
24、ned inACI Specification 308.1M. The Specifier must include theserequirements in the Project Specification.F5. The Optional Requirements Checklist identifiesSpecifier choices and alternatives. The Checklist identifies theSections, Parts, and Articles of the ACI Reference Specification308.1M and the a
25、ction required or available to the Specifier. TheSpecifier should review each of the items in the Checklist andmake adjustments to the needs of a particular project by includingthose selected alternatives as mandatory requirements in theProject Specification.Donald L.

ACI Spec
35、ification 308.1M is to be used by referenceor incorporation in its entirety in the Project Specification.Do not copy individual Sections, Parts, Articles, or Paragraphsinto the Project Specification, because taking them out ofcontext may change their meaning.P2. If Sections or Parts of ACI Specifica
36、tion 308.1M arecopied into the Project Specification or any other document,do not refer to them as an ACI Specification, because thespecification has been altered.P3. A statement such as the following will serve to makeACI Specification 308.1M a part of the Project Specification:“Work on (Project Ti
37、tle) shall conform to all requirements ofACI 308.1M, Specification for Curing Concrete, published bythe American Concrete Institute, Farmington Hills, Michigan,except as modified by these Contract Documents.”P4. Each technical section of ACI Specification 308.1M iswritten in the three-part Section f
38、ormat of the ConstructionSpecifications Institute, as adapted for ACI requirements.The language is imperative and terse.P5. ACI Specification 308.1M is written to the Contractor.When a provision of this Specification requires action by theContractor, the verb “shall” is used. If the Contractor is al
39、lowedto exercise an option when limited alternatives are available, thephrasing “either.or.” is used. Statements provided in theSpecification as information to the Contractor use the verbs“may” or “will.” Informational statements typically identifyactivities or options that “will be taken” or “may b
40、e taken” by theOwner or Architect/Engineer. P6. When ACI 301, “Specifications for Structural Concrete,”is referenced in a Project Specification, this Specificationshall not be referenced.Mandatory requirements checklistThe specifier is to determine the desired results of thecuring and select the app
41、ropriate section or sections toachieve those results if a particular curing method isdesired. The Specifier is to use ACI 308R, “Guide toCuring Concrete,” as commentary for making decisionswithin the checklists. The alternative methods described ineach section of this specification are not necessari
42、ly equalin effectiveness, cost, effect on project schedule, or impacton other aspects of the project. To use this specification,the Architect/Engineer must not only include this documentby reference in the Project Specification, but must alsoreview and respond to the checklists. It is imperative tha
43、tthe Architect/Engineer annotate this specification to meetthe project requirements through the checklists. TheArchitect/Engineer must identify the concrete elementsthat are to be cured and must choose the method to curethem. Further, the Architect/Engineer must determinewhether deliberate curing ef
44、forts must or may terminateafter a predetermined time has elapsed, or only afterparticular levels of concrete properties have developed.When deliberate efforts to cure the concrete are to beterminated only when particular concrete properties havedeveloped, the Architect/Engineer must also select the
45、 testmethod used to measure those properties. Checklists areprovided in this document to guide the Architect/Engineerthorough these selection processes, and the selections mustbe included in the Project Specification.SPECIFICATION FOR CURNG CONCRETE (ACI 308.1-11) 3American Concrete Institute Copyri
