1、Designation: C 129 06Standard Specification forNonloadbearing Concrete Masonry Units1This standard is issued under the fixed designation C 129; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in
2、parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers hollow and solid nonloadbear-ing con
3、crete masonry units made from portland cement, water,and mineral aggregates with or without the inclusion of othermaterials. These units are intended for use in nonloadbearingpartitions, but under certain conditions they may be suitable foruse in nonloadbearing exterior walls above grade whereeffect
4、ively protected from the weather.1.2 The text of this standard references notes and footnoteswhich provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be consideredas requirements of the standard.1.3 The values stated in inch-pound units are to be
5、 regardedas the standard. The values given in parentheses are forinformation only.NOTE 1Concrete masonry units covered by this specification aremade from lightweight or normal weight aggregates, or both.NOTE 2When particular features are desired, such as density classi-fication, surface texture for
6、appearance or bond, finish, color, fireresistance, insulation, acoustical properties, or other special features, suchproperties should be specified separately by the purchaser. However,suppliers should be consulted as to the availability of units having thedesired features.2. Referenced Documents2.1

16、s or shall be shown by test or experience not tobe detrimental to the durability of the concrete masonry unitsor any material customarily used in masonry construction.6. Physical Requirements6.1 At the time of delivery to the purchaser, units shallconform to the strength requirements prescribed in T
17、able 2.NOTE 3The purchaser is the public body or authority, association,corporation, partnership, or individual entering into a contract or agree-ment to purchase or install, or both, concrete masonry units. The time ofdelivery to the purchaser is FOB plant when the purchaser or purchasersagent tran
18、sports the concrete masonry units, or at the time unloaded at theworksite if the manufacturer or manufacturers agent transports theconcrete masonry units.6.2 At the time of delivery to the purchaser, the total lineardrying shrinkage of units shall not exceed 0.065%.6.3 Solid UnitsThe net cross-secti
19、onal area of solid units,in every plane parallel to the bearing surface, shall be not lessthan 75 % of the gross cross-sectional area measured in thesame plane.7. Dimensions and Permissible Variations7.1 Minimum face shell thickness shall be not less than12in. (13 mm).7.2 No overall dimension (width
20、, height, and length) shalldiffer by more than 618 in. (3.2 mm) from the specifiedstandard dimensions.NOTE 4Standard dimensions of units are the manufacturers desig-nated dimensions. Nominal dimensions of modular size units are equal tothe standard dimensions plus the thickness of one mortar joint.
21、Nominaldimensions of nonmodular size units usually exceed the standard dimen-sions by18 to14 in. (3.2 to 6.4 mm).8. Finish and Appearance8.1 All units shall be sound and free of cracks or otherdefects that interfere with the proper placement of the units orsignificantly impair the strength or perman
22、ence of the construc-tion. Minor cracks incidental to the usual method of manufac-ture or minor chipping resulting from customary methods ofhandling in shipment and delivery are not grounds for rejec-tion.8.2 Where units are to be used in exposed wall construction,the face or faces that are to be ex
23、posed shall not show chips orcracks, not otherwise permitted, or other imperfections whenviewed from a distance of not less than 20 ft (6.1 m) underdiffused lighting.8.2.1 Five percent of a shipment containing chips, not largerthan 1 in. (25.4 mm) in any dimension, or cracks not wider than0.02 in. (
24、0.5 mm) and not longer than 25 % of the nominalheight of the unit is permitted.8.3 The color and texture of the units shall be specified bythe purchaser. The finished surfaces that will be exposed inplace shall conform to an approved sample consisting of notless than four units, representing the ran
25、ge of texture and colorpermitted.8.4 Nonloadbearing concrete masonry units shall be clearlymarked in a manner to preclude their use as load bearing units.9. Methods of Sampling and Testing9.1 The purchaser or authorized representative shall beaccorded proper facilities to inspect and sample the unit
26、s at theplace of manufacture from the lots ready for delivery.9.2 Sample and test units in accordance with Test MethodsC 140 and Test Method C 426 when applicable.9.3 Total linear drying shrinkage shall be based on tests ofconcrete masonry units made with the same materials, concretemix design, manu
27、facturing process, and curing method, con-ducted in accordance with Test Method C 426 not more than 24months prior to delivery.10. Compliance10.1 If a sample fails to conform to the specified require-ments, the manufacturer shall be permitted to remove unitsfrom the shipment. A new sample shall be s
28、elected by thepurchaser from remaining units from the shipment with asimilar configuration and dimension and tested at the expenseof the manufacturer. If the second sample meets the specifiedrequirements, the remaining portion of the shipment repre-sented by the sample meets the specified requiremen
29、ts. If thesecond sample fails to meet the specified requirements, theremaining portion of the shipment represented by the samplefails to meet the specified requirements.NOTE 5Unless otherwise specified in the purchase order, the cost oftests is typically borne as follows: if the results of the tests
30、 show that theunits do not conform to the requirements of this specification, the cost istypically borne by the seller. If the results of the tests show that the unitsconform to the specification requirements, the cost is typically borne bythe purchaser.11. Keywords11.1 concrete masonry units; face
