Microscopical Examination of Portland Cement and Clinker - ONO Method

This examination is performed on raw cement and clinker, to assess proportions of clinker phases and evaluate various clinker phase characteristics associated with the cement raw mix and conditions in the cement kiln during production. The examination is mainly used as a troubleshooting tool and as part of a quality control program, often in conjunction with XRD, XRF, and other testing.

As a result of our connection with the Portland Cement Association, CTLGroup has a long and distinctive history in the development of microscopical methods for evaluating cement and clinker. Our petrographers have had the benefit of extensive training with pioneers in the field, and are uniquely positioned to troubleshoot cement issues as well as handle routine quality assessments.
