Selecting and using raw materials for cement manufacture

** This course is undergoing some maintenace and will be unavailable for new registrations whilst the content is updated. Please email with any queries. **

Course Introduction and approach

A new, instant access, online course, comprising of 14 lectures covering all aspects of raw material exploration, planning, extraction and preparation for use as cement clinker kiln feed.

The course is open to all in the cement industry and a fee will be charged for each student, with discounts offered to group bookings.

The course is based on self-learning, allowing students flexibility to follow the lectures at work or home. As well as the lecture slides, the links form an important part of the learning so time should be allowed to follow these and further into the subject where appropriate. A computer with internet access (broadband recommended) and email capabilities will be necessary to follow this course.

Course certification

Participants who successfully pass the end of course exam are posted a course certificate for their training record.
