Standard: ASTM C403, AASHTO T197

Product Description

The Concrete Penetration Apparatus is an equipment used in determining the resistance of concrete to penetration. This test is often conducted to evaluate the quality and strength of concrete in construction projects. The apparatus typically consists of penetrometer probe with a pointed tip that is driven into the concrete surface under a constant load. The penetration depth is measured either manually or automatically by the device. The resistance encountered during penetration is indicative of the concrete's hardness, density, and overall strength. 

Features of Concrete Penetration Apparatus

  • Penetrometer Probe designed with a pointed tip  to penetrate the concrete surface. Comes is various sizes and shape depending o the specific specification and standards being followed. 
  • Load Application Mechanism which helps in applying a constant load to the penetrometer probe during the penetration test. This ensures consistency and accuracy in the results. 
  • It provides a depth measurement system which is essential for accurately determining the penetration depth of the probe into the concrete. 
  • The apparatus is typically constructed from durable materials such as stainless steel or hardened alloys to withstand the forces exerted during penetration tests and ensure longevity.

Standard: ASTM C403, AASHTO T197

  • ASTM C403

ASTM C403 is a standard developed by ASTM International, formerly known as the American Society for Testing and Materials. This standard provides a reliable and standardised approach for assessing the crucial transition points of concrete from its initial workable state to its final hardened form by quantifying the resistance encountered by a penetrating needle, ensuring accurate determination of setting times for various construction applications. 

  • AASHTO T197

AASHTO T197, also known as "Standard Method of Test for Penetration Resistance of Hardened Concrete," provides similar guidelines to ASTM C403 for determining the setting time of concrete mixtures through penetration resistance measurements. This standard is specifically developed by the American Association of State Highway and Transportation Officials (AASHTO) and is commonly used in the transportation and infrastructure sectors for quality control and assurance of concrete materials and structures. The test involves driving a hardened steel probe into the surface of the concrete under a constant load and measuring the depth of penetration to assess the concrete's hardness and strength.

Test Procedure

  1. Prepare Concrete: Make cylindrical concrete samples and let them cure.
  2. Set Up Apparatus: Arrange the concrete penetration tool as instructed.
  3. Choose Parameters: Decide on the probe size, load, and testing intervals.
  4. Perform Test:
    • Place the concrete sample on the apparatus.
    • Push the probe into the concrete while measuring resistance.
    • Record how deep the probe goes and how much resistance it encounters.
  5. Analyse Data: Look at the numbers to understand how strong the concrete is.
  6. Report Findings: Write down what you discovered in a clear report.
  7. Check Equipment: Clean and maintain the tool for future use.
