Jun 26, 2013 · Core strengths represent the quality of the inplace, or insitu, concrete which in addition to concrete batching, mixing, transportation and testing is influenced by jobsite practices such as ...
The lock feature protects cores from damage during extraction and assures laboratory acceptance for testing without repeat drilling. Models for 4in (102mm) or 6in (152mm) core sizes have identical features and operation. Extractors are welded, painted steel with sturdy handle grips. CDA18 extracts 4in asphalt or concrete cores.

CORE EXTRACTION TEST. Core Extraction test is used to determine the compressive strength of a concrete core, which has usually been extracted from an existing structure. The value of compressive strength can then be used in conjunction with other measured properties to assess the condition of the concrete. Using a masonry saw, the core is first ...
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. 3 These factors shall be considered in planning the loions for obtaining concrete samples and in comparing strength test .
Analytical testing laboratories, like CTL, are known for conducting inhouse and onsite testing of materials used for bridges, buildings, subgrades, structural fills, roadways, and earthen and concrete dams. In addition to the standard tests that are required by the specifiion, we perform specific tests on construction materials as dictated ...
Nowadays concrete core test is a famous and wellestablished method for the assessment of the compressive strength of the hardened concrete. Core testing enables visual inspection of the interior regions of a concrete member which is also related to strength estimation. Concrete coring also enables to evaluate other properties of the Reinforced Concrete Framed Structure by concrete core test.
A piezoelectric transducer emitting vibration at its fundamental frequency is placed in contact with the concrete surface so that the vibrations travel through the concrete and are received by another transducer, which is in contact with the opposite face of the test object.
