Cement Testing

NNL has extensive experience in providing customers with a cement sample testing service. Over many years, our industry-leading understanding of cement behaviours has been developed through hands on testing, supporting an in-depth investigation of the effects of cement encapsulation on uranium.

Our Service

NNL can offer customers a range of tests, including:

  • Cement set time using the 'Vicat Method'
  • Assessment of sample defects within the prepared cement test samples using ultrasonic pulse velocity testing
  • Compressive strength testing
  • Dimensional stability

We then use this information to provide customers with a comprehensive assessment of the physical nature of cement samples, enabling them to make informed decisions about the suitability of particular cement mixes.

Outstanding Equipment

NNL's expert team has a range of specialist laboratory testing equipment available to help provide the highest level of service for our customers. Equipment includes:

  • An ELE International automatic 200kN compressive strength-testing rig. This equipment allows for the consistent automatic testing of a range of specimens, with calibration accuracy to BS EN ISO 7500-1 & ASTM E4 quality standards
  • An ELE International cement prism sample length comparator. The dimensional stability of cement systems are typically measured in units of strain, which is defined as the amount of deformation per unit length of an object when a load is applied
  • A 'Pundit' ultrasonic pulse velocity-testing instrument together with all the associated transducers. The basis of this technique is that where there are any voids (of whatever size) present in the test material, these will affect the speed of signal transmission through the material
