1、Designation:C1583/C1583M13Standard Test Method forTensile Strength of Concrete Surfaces and the BondStrength or Tensile Strength of Concrete Repair and OverlayMaterials by Direct Tension(Pull-off Method)1This standard is issued under the fixed designation C1583/C1583M;the number immediately followin
2、g the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is suitabl
3、e for both field and laboratoryuse to determine one or more of the following:1.1.1 The near-surface tensile strength of the substrate as anindicator of the adequacy of surface preparation before appli-cation of a repair or overlay material.1.1.2 The bond strength of a repair or an overlay material t

8、ication of a concrete repair or overlaymaterial,or on the surface of a concrete repair or overlaymaterial after the material has been applied to the preparedconcrete surface.4.2 The test specimen is formed by drilling a shallow coreinto and perpendicular to the surface of the substrate,andleaving th
9、e intact core attached to the concrete.A steel disk isbonded to the top surface of the test specimen.4.3 A tensile load is applied to the steel disk until failureoccurs.The failure load and the failure mode are recorded andthe nominal tensile stress at failure is calculated.5.Significance and Use5.1
10、 This test method determines the tensile strength ofconcrete near to the prepared surface,which can be used as anindicator of the adequacy of surface preparation before apply-ing a repair or an overlay material.5.2 When the test is performed on the surface of a repair oran overlay material,it determ
11、ines the bond strength to thesubstrate or the tensile strength of either the overlay orsubstrate,whichever is weaker.5.3 The method may also be used to evaluate the adhesivestrength of bonding agents.5.4 When the test is performed on the surface of a materialapplied to the substrate,the measured str
12、ength is controlled bythe failure mechanism requiring the least stress.Thus it is notpossible to know beforehand which strength will be measured1This test method is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregatesand is the direct responsibility of SubcommitteeC09.25 o
