This test method is for the determination of the compressive strength of 2-in (50 mm) hydraulic cement mortar cubes. The test method consists of applying a compressive axial load at a prescribed rate until failure occurs.  The compressive strength of the mortar is calculated by dividing the maximum load by the cross-sectional area.

 

Data entry and calculations for this test are performed on the Mortar Compressive Strength form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the reporting section below. The format of this report is controlled by the geotechnical template used for the test.

 

The methodology and calculations for this test adhere to "ASTM C109/C109M-07 Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)". For more detailed information on the methodology and calculations please review this standard.
