The Applied Technical Services Family of Companies (ATS FoC) conducts ASTM C31 concrete testing to verify the quality of concrete cured at job sites. ASTM C31 is the industry standard for preparing and curing concrete test specimens.
Adhering to the ASTM C31 process helps contractors and engineers to achieve accurate, repeatable, and reliable concrete test results, supporting quality control and regulatory compliance on construction projects.
What Factors Affect the Results of Cured Concrete?
The accuracy of concrete strength and durability depends on how test specimens are handled during curing, molding, consolidation, and transport. Several factors can influence the quality of cured concrete and the validity of test results, such as:
- Temperature variations
- Moisture retention
- Moisture loss
- Handling, shock, vibration
- Timing and transportation
Even small deviations from ASTM C31 standards can reduce compressive strength, potentially leading to concrete failure.
How ASTM C31 is Applied in Concrete Testing
From sampling to final testing, ASTM C31 concrete testing process follows key steps:
Sampling: Fresh concrete is collected during placement to ensure a representative sample.
Specimen Preparation: Cylinders are molded, consolidated, and finished in accordance with ASTM C31.
Initial Curing: Specimens are stored on-site for 24–48 hours under controlled conditions.
Laboratory Curing: Cylinders are transported to a lab and cured under controlled temperature and moisture conditions.
Concrete Strength Testing (ASTM C39): Cylinders are tested at 7 and 28 days to verify compressive strength.
