This test method determines the tensile strength cylindrical concrete specimens obtained from molds or drilled cores. The test method involves applying a diametral compressive force along the length of the cylindrical concrete specimen at a prescribed rate until failure occurs. Tensile strength is obtained by dividing the maximum load by the appropriate geometrical factors.

 

Data entry and calculations for this test are performed on the Concrete Tensile 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 C496/C496M-11 Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete Specimens". For more detailed information on the methodology and calculations please review this standard.
