ASTM C803
Full Name
ASTM C803 – Standard Test Method for Penetration Resistance of Hardened Concrete
Scope
ASTM C803 is a standard test method used to determine the penetration resistance of hardened concrete. This test method can be done using either a steel probe or pin. The probe or pin is driven into the concrete with a driver that delivers a known amount of energy. The penetration resistance is then determined by measuring either the exposed length of the probes or the depth of the holes created by the pins.
Key aspects covered in ASTM C803:
- Purpose: the primary purpose is to assess the uniformity of concrete and to identify areas of poor quality or deterioration in structures.
- Applicability: the test method is applicable to various types of hardened concrete, including both in-place and laboratory specimens.
- Equipment: it specifies the requirements for the drivers, probes, and pins used in the test.
- Procedure: it outlines the steps involved in conducting the test, including surface preparation, driver selection, and measurement of penetration resistance.
- Calculations: it provides formulas for calculating the average penetration resistance and standard deviation.
- Reporting: it details the information that should be included in the test report.
Limitations:
- The test results are influenced by factors such as the concrete strength, aggregate type, and moisture content.
- The test method does not directly measure the compressive strength of concrete.
By following ASTM C803, engineers and technicians can gain valuable insights into the quality and condition of hardened concrete structures, aiding in maintenance, repair, and rehabilitation decisions.
