Eurolabs AASHTO T24 Air Content of Hydraulic Cement Concrete by Pressure Method Laboratory Testing Service

Standard-Related Information

The Air Content of Hydraulic Cement Concrete by Pressure Method (AASHTO T24) is a laboratory test used to determine the air content of fresh hydraulic cement concrete. This test method is widely recognized and accepted globally, with various standards governing its implementation.

International Standards:

  • ISO 6707-1:2005 - Geometrical properties of roads, airfields and working areas - Part 1: Measurement of pavement surface

  • ASTM C231/C231M - Standard Test Method for Air Content of Freshly Mixed Hydraulic-Cement Concrete by the Pressure Method

  • EN 12390-7:2019 - Testing hardened concrete. Density of hardened concrete

    • National Standards:

  • TSE (Turkish Standard) 7051:2008 - Hydraulic cement concrete. Determination of air content by pressure method

  • AASHTO TP 43:2014 - Standard Test Method for Air Content of Freshly Mixed Hydraulic-Cement Concrete by the Pressure Method

    • Standard Development Organizations and Their Role:

    The development and maintenance of standards related to laboratory testing are carried out by various organizations, including:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)
