Abstract
A cement sample testing apparatus including a first pressure zone; a second pressure zone; and a pressure control system. The pressure control system can be in fluid communication with the first pressure zone and the second pressure zone, operable to raise the first pressure zone to a first pressure above ambient pressure, and operable to raise the second pressure zone to a second pressure above ambient pressure. A method for determining mechanical properties for a sample cement composition can include applying a first pressure condition to a first portion of the sample cement composition; applying a second pressure condition raised to a second portion of the sample cement composition; and determining one or more mechanical properties of the sample cement composition based at least in part on the pressure conditions present at the failure of the sample cement composition.
