1、Designation: C387/C387M 17Standard Specification forPackaged, Dry, Combined Materials for Concrete and HighStrength Mortar1This standard is issued under the fixed designation C387/C387M; the number immediately following the designation indicates the yearof original adoption or, in the case of revisi
2、on, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers the production, properties,packaging, and testing of packaged, dry, combine
3、d materialsfor concrete and high strength mortar. The classifications ofconcrete and mortar covered are defined in Section 3.NOTE 1The scope of this standard does not cover mortars for unitmasonry. Dry preblended mortars for unit masonry are covered bySpecification C1714/C1714M.1.2 The values stated
4、 in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. Some va
5、lues have only SI units because theinch-pound equivalents are not used in practice.1.3 The following safety hazards caveat pertains only to thetest method portion of this specification. This standard does notpurport to address all of the safety concerns, if any, associatedwith its use. It is the res
6、ponsibility of the user of this standardto establish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior touse.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in

Rejectionshall be reported to the Producer or supplier promptly and inwriting.11.2 The purc
38、haser has the right to reject product indamaged or dampened containers.12. Storage12.1 Product must be stored in a dry area and shall not bestored in direct contact with the ground or floor.SAMPLING AND TESTING13. Accuracy of Measurement13.1 Use scales conforming to the applicable sections ofHandboo
39、k 44.3New and reconditioned scales shall be accurateto 60.1 % of the total capacity of the scale. When scales havebeen in use, they shall be accurate to 60.4 % of the totalcapacity of the scale.13.2 Record the mass of concrete in kilograms (pounds) toa minimum accuracy of 0.05 kg 0.1 lb. Record the
40、mass ofmortar in grams to an accuracy of within1gor0.1%,whichever is greater.14. Sampling Concrete14.1 Use a sufficient quantity of whole packages to conductall testing from a single batch.15. Mixing and Testing Concrete15.1 Determine the net mass of concrete in the package (orpackages), then empty
41、into a clean, watertight container.15.2 Mix the concrete, determine the properties of the freshconcrete, and mold and cure the specimens in accordance withthe applicable provisions of Practice C192/C192M, or modifi-cations of them as outlined herein. Test the strength of theconcrete in accordance wi
42、th Test Method C39/C39M.15.3 Mix the entire sample of the combined, dry material forconcrete either by hand or by machine, except that hand mixingis not applicable to air-entrained concrete.Add mixing water insufficient amount to produce a slump of 50 to 75 mm 2 to 3in.15.4 Use a watertight, clean m
43、etal container for handmixing, using either a blunted bricklayers trowel, handsprotected by rubber gloves, or a shovel, whichever is moreconvenient. Mix the dry batch until the materials appear to beuniformly distributed. Add water while mixing until the con-crete is homogeneous in appearance and ha
44、s the desired slump.If prolonged mixing is required because of the addition ofmixing water in increments while adjusting the slump, thebatch must be discarded and a new batch made withoutinterrupting the mixing to make trial slump tests.3Specifications, Tolerances, and Other Technical Requirements o
45、f Weighing andMeasuring Devices, Handbook 44, National Bureau of Standards.C387/C387M 17315.5 Place all materials in the mixer to be used for machinemixing. A mixing period of 3 min followed by a 3-min rest,followed by 2-min final mixing is suggested, unless a differentprocedure is better adapted to
46、 the mixer being used. Cover theopen end of the mixer during the rest period to reduceevaporation. Test the slump in accordance with Test MethodC143/C143M upon completion of the mixing. If the slump testof the mixed batch shows that additional water is required,return the sample used for the slump t
47、est promptly to the mixer,add additional water, and remix the batch for 2 min. Retest theslump. If the slump is not from 50 to 75 mm 2 to 3 in., discardthe batch.15.6 Discharge the mixed batch into a clean, watertightcontainer that has been predampened, then remix the batch byhand, using a scoop or
48、trowel, until the batch appears to beuniform. Promptly determine the density in kilograms percubic meter (or pound per cubic foot) in accordance with TestMethod C138/C138M. Return samples used for the slump andunit weight test to the container, then remix the batch by handand mold the specimens.15.7
49、 Mold six cylinders from each batch, using threecylinders for test at 7 days and three at 28 days, except that inthe case of high early strength concrete, three cylinders shall betested at 3 days and three at 7 days. Compression testspecimens shall be cylindrical with a length equal to twice thediameter. The minimum specimen diameter shall be 75 mm 3in., but the maximum diameter is not limited, provided thenumber of specimens for a test as required in this section aremolded from a single batch and the sampl
