1、Designation:C803/C803M18Standard Test Method forPenetration Resistance of Hardened Concrete1This standard is issued under the fixed designation C803/C803M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A nu
2、mber 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 test method covers the determination of the resis-tance of hardened concrete to penetration by either a steelprobe or pin.1.2 The valu
