ASTM C174
Full Name
ASTM C174 – Standard Test Method for Measuring Thickness of Concrete Elements Using Drilled Concrete Cores
Scope
ASTM C174 covers the determination of the thickness of concrete elements, such as pavements, slabs, or structural components, by measuring the length of cores drilled from the structure.
Specifically, the standard addresses:
- Purpose: the main purpose is to verify if the concrete element’s thickness complies with design specifications.
- Specimen: the test requires at least one end of the drilled core to be a finished or formed surface.
- Apparatus: it describes the apparatus for measuring the core length, which should accommodate cores of varying lengths and enable measurements at multiple points on the core’s surface.
- Procedure: it outlines the steps involved in measuring the length of the core, including the placement of the core, alignment of the measuring device, and recording the measurements.
- Calculations: it provides instructions for calculating the average thickness of the concrete element based on the measured lengths of the cores.
- Report: it details the information that should be included in the test report, such as the identification of the structure, location of the core, average thickness, and any deviations from the standard procedure.
ASTM C174 does not cover:
- Strength testing: this standard is specifically for thickness measurement and does not address the strength properties of the concrete.
- Safety concerns: the standard does not include safety precautions related to the drilling and handling of concrete cores.
It’s important to note that ASTM C174 is often used in conjunction with other test methods, such as ASTM C42, to evaluate the overall quality and compliance of concrete structures.
