A redline edition is available for this document, with all changes visible. Ask Document Center Inc. This test method is not applicable to cores from shotcrete. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in non-conformance with the standard. These notes and footnotes astm c42 pdf download those in tables and figures shall not be considered as requirements of the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Another use of this method is to provide strength information astm c42 pdf download older structures. Core strength is also affected by core orientation relative to the horizontal plane of the concrete as placed, with strength tending to be lower when measured parallel to the horizontal plane. There is no standard procedure to condition a specimen that will ensure that, at the time of test, it will be in the identical moisture condition as concrete in the structure.
The moisture conditioning procedures in this test method are intended to provide reproducible moisture astm c42 pdf download that minimize within-laboratory and between-laboratory variations and to reduce the effects of moisture introduced during specimen preparation, astm c42 pdf download. For a given concrete, however, there is no unique relationship between the strengths of these two types of specimens see Note 3.
The relationship is affected by many factors such as the strength level of the concrete, the in-place temperature and moisture histories, the degree of consolidation, batch-to-batch variability, astm c42 pdf download, the strength-gain characteristics of the concrete, the condition of the coring apparatus, and the care used in removing cores. An example of acceptance criteria for core strength is provided in ACI5 which are used to evaluate cores taken to investigate low strength test results of standard-cured cylinder during construction.
