AASHTO T 106M/T 106 Standards for Cement Tests

AASHTO T 106M/T 106 is a standard developed by the American Association of State Highway and Transportation Officials (AASHTO) that pertains to the determination of the specific gravity and absorption of fine aggregate. This standard provides guidelines and procedures for measuring the specific gravity and water absorption characteristics of fine aggregate, such as sand.

Products associated with AASHTO T 106M/T 106 include specific gravity and absorption testing equipment. The standard outlines the use of a pycnometer or a similar apparatus for determining the specific gravity of the fine aggregate. The pycnometer allows for precise measurement of the volume of the aggregate and its weight in both dry and saturated conditions.

Additionally, the standard specifies the use of an oven and a suitable container for drying the fine aggregate, as well as a suitable container for soaking the aggregate in water. These products enable the determination of water absorption characteristics, which are important in assessing the quality and performance of fine aggregate in concrete and asphalt mixtures.

By adhering to AASHTO T 106M/T 106, engineers, researchers, and material producers can ensure consistent and reliable measurement of the specific gravity and absorption of fine aggregate. This information is crucial in proportioning concrete and asphalt mixtures, as well as assessing their workability, strength, and durability.
