ASTM A615/A615M-15a 混凝土钢筋用变形和普通碳素钢筋的标准规格

1.1 This specification covers deformed and plain carbon-steel bars in cut lengths and coils for concrete reinforcement. Steel bars containing alloy additions, such as with the Association for Iron and Steel Technology and the Society of Automotive Engineers series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. (A) The nominal dimensions of a deformed bar are equivalent to those of a plain round bar having the same weight [mass] per foot [metre] as the deformed bar.(B) Refer to Note 2. 1.2 Bars are of five minimum yield strength levels: namely, 408201;000 psi [280 MPa], 608201;000 psi [420 MPa], 758201;000 psi [520 MPa], 808201;000 psi [550 MPa], and 100 000 psi [690 MPa], designated as Grade 40 [280], Grade 60 [420], Grade 75 [520], Grade 80 [550], and Grade 100 [690], respectively. Note 1: Grade 100 [690] reinforcing bars were introduced in this specification in 2015. In contrast to the lower grades, which have ratios of specified tensile strength to specified yield strength that range from 1.31 to 1.5, Grade 100 [690] reinforcing bars have a ratio of specified tensile strength to specified yield strength of 1.15. Designers should be aware that there will, therefore, be a lower margin of safety and reduced warning of failure following yielding when Grade 100 [690] bars are used in structural members where strength is governed by the tensile strength of the reinforcement, primarily in beams and slabs. If this is of concern, the purchaser has the option of specifying a minimum ratio of tensile strength to actual yield strength. Consensus design codes and specifications such as “Building Code Requirements for Structural Concrete (ACI 318)” may not recognize Grade 100 [690] reinforcing bars: therefore the 125 % of specified yield strength requirements in tension and compression are not applicable. Mechanical and welded splices should meet a minimum specified tensile strength of 115 000 psi [790 MPa]. Note 2: Designers need to be aware that design standards do not recognize the use of the No. 20 [64] bar, the largest bar included in this specification. Structural members reinforced with No. 20 [64] bars may require approval of the building official or other appropriate authority and require special detailing to ensure adequate performance at service and factored loads. 1.3 Plain bars, in sizes up to and including 21/2 in. [63.5 mm] in diameter in coils or cut lengths, when ordered shall be furnished under this specification in Grade 40 [280], Grade 60 [420], Grade 75 [520], Grade 80 [550], and Grade 100 [690]. For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Requirements providing for deformations and marking......

Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement

ASTM C876-15 混凝土中无涂层钢筋的腐蚀电位的标准试验方法

4.1 This test method is suitable for in-service evaluation and for use in research and development work. 4.2 This test method is applicable to members regardless of their size or the depth of concrete cover over the reinforcing steel. Concrete cover in excess of 3 in. (75 mm) can result in an averaging of adjacent reinforcement corrosion potentials that can result in a loss of the ability to discriminate variation in relative corrosion activity. 4.3 This test method may be used at any time during the life of a concrete member. 4.4 The results obtained by the use of this test method shall not be considered as a means for estimating the structural properties of the steel or of the reinforced concrete member. 4.5 The potential measurements should be interpreted by engineers or technical specialists experienced in the fields of concrete materials and corrosion testing. It is often necessary to use other data such as chloride contents, depth of carbonation, delamination survey findings, rate of corrosion results, and environmental exposure conditions, in addition to corrosion potential measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure. 1.1 This test method covers the estimation of the electrical corrosion potential of uncoated reinforcing steel in field and laboratory concrete, for the purpose of determining the corrosion activity of the reinforcing steel. 1.2 This test method is limited by electrical circuitry. Concrete surface in building interiors and desert environments lose sufficient moisture so that the concrete resistivity becomes so high that special testing techniques not covered in this test method may be required (see 5.1.4.1). Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit. The basic configuration of the electrical circuit is shown in Fig. 1. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

It is the responsibility of the user of this specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM A970/A970M-15 混凝土钢筋用有头钢棒材的标准规格

1.1 This specification covers deformed steel reinforcing bars in cut lengths, with a head attached to one or both ends, for concrete reinforcement. Heads are forge-formed, machined from bar stock, or cut from plate. Attachment can be accomplished through: 1.1.1 Welding; 1.1.2 Integrally hot forging of a head from the reinforcing bar end; 1.1.3 Internal threads in the head mating to threads on the bar end; 1.1.4 Cold-swaging an externally threaded coupling sleeve onto the reinforcing bar; 1.1.5 Cold-extruding an external coupling sleeve onto the reinforcing bar; 1.1.6 Cold-swaging an external coupling sleeve or headed sleeve onto the reinforcing bar; 1.1.7 Attaching a coupling sleeve to the end of the reinforcing bar by means of the means of a ferrous-filler medium; or 1.1.8 Separate threaded nut to secure the head to the bar. Note 1: The requirements of this specification are only applicable to headed bars where the attachment of the head is accomplished by one of the methods listed in 1.1. 1.2 Limitations on head dimensions and on obstructions and interruptions of bar deformations on the non-planar features on the bearing face of the head are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser (see 4.1.13). 1.3 This specification is applicable for orders in either inch-pound units as Specification A970 or SI units as Specification A970M. 1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This International Standard specifies rules for a certification scheme for continuous production of welded fabric for ordinary reinforcement of concrete structures, in order to verify the conformity with requirements specified in product standards such as ISO 6935-3. A certification scheme for continuous production consists of the following stages: — suitability testing (see clause 4); — internal inspection by the manufacturer (see clause 5); — inspection and supervision by an external body (see clause 6).
