AASHTO T106

Full Name

AASHTO T106 – Standard Method of Test for Compressive Strength of Hydraulic Cement Mortar (Using 50-mm or 2-in. Cube Specimens)

Scope

AASHTO T106 is a standard test method used to determine the compressive strength of hydraulic cement mortar. This test is essential for assessing the quality and consistency of hydraulic cements, such as Portland cement, blended cement, and masonry cement. The compressive strength of mortar is a key indicator of the cement’s ability to bind aggregates and provide structural integrity in concrete and mortar applications.

Key aspects of AASHTO T106:

  • Specimen preparation: mortar specimens are prepared using a standard mix design consisting of cement, sand, and water. The specimens are typically 50-mm or 2-inch cubes, which are compacted and cured under controlled conditions.
  • Testing procedure: after curing, the specimens are subjected to a compressive load using a testing machine. The load is gradually increased until the specimen fails, and the maximum load at failure is recorded.
  • Calculation: the compressive strength of the mortar is calculated by dividing the maximum load by the cross-sectional area of the specimen.
  • Significance: the compressive strength of mortar is a critical parameter for evaluating the quality and performance of hydraulic cements. It is used to determine compliance with specifications, predict the strength of concrete, and assess the suitability of cement for various applications.

Importance of AASHTO T106:

  • Quality control: by adhering to AASHTO T106, cement manufacturers and testing laboratories can ensure the consistency and quality of their cement products. This is crucial for producing high-quality concrete and mortar that meet the desired performance and durability standards.
  • Performance assessment: the compressive strength of mortar is a reliable indicator of the cement’s potential performance in concrete and mortar applications. This information is valuable for engineers and contractors when selecting cement for specific projects.
  • Standardized testing: AASHTO T106 provides a standardized test method for determining the compressive strength of mortar, ensuring consistency and reliability in test results across different laboratories and projects.
