Testing mechanical properties

A system for testing cement, comprising:

• a testing vessel having interior walls defining a mold cavity to receive the cement;
• and
• a body in the mold cavity adapted to apply a specified pressure to the cement while it is being received in the mold cavity;
• a load arm operable to load the cement in tension until a bond between the cement and the interior walls fails;
• the load arm adapted to contact the cement and apply a testing load to the cement, the interior walls of the testing vessel configured to anchor the cement against the testing loads;
• the load arm operable to load the cement in tension until failure at a break area;
• and
• wherein the testing vessel is adapted to mold the cement in an annular shape about the break area.

A method for testing cement, comprising:

• receiving a cement in a testing vessel, the cement curing in the testing vessel;
• testing a shear bond strength of the cement, the cement cured and tested while applying a specified temperature and/or pressure;
• and
• loading the cement in tension until the cement breaks before testing the shear bond strength of the cement.
