Determining how to test the bond strength of cement involves a three step process. The first step is to determine the bond that is to be tested, the temperature at which it will be tested and the condition of the cement. Is the cement itself acting as the adhesive and bonding two other materials together? Is the bond to be tested at elevated temperatures or is it to be tested below subzero temperatures? Is the cement wet or dry? This will help to determine which machine to use and its accessories. The next step is to determine which type of test to perform. This will aid in the selection of the testing fixtures as each type of test will require a fixture that will allow the sample to be properly orientated so that the bond experiences the specific stress designated by the test. Is the cement acting as an adhesive between two stones that will experience shear stress? Is the cement holding a metal rod that will experience torsion? Then the test will range from anywhere between a tensile test to a shear test to a flexural test or any combination of those and will depend upon which way the cement bond is stressed during the test. The final step is to determine the shape and setup of the cement sample that is used during the test. Is the cement holding two bricks together or is it acting as a ground anchor into which a metal rod has been placed, such as for a basketball pole? This will also help to determine which testing fixture to use during the test as certain shapes and setups will require unique fixtures to hold them.
