1
In 2012, 4 billion tons of cement were produced worldwide.
2
This makes concrete the product most consumed by humans.
3
Compared to many other materials, producing cement is very ecological, but with several billion of tons produced each year,
4
the cement industry becomes a major contributor to global CO2 emissions.
5
To reduce its impact, we can substitute a part of cement by supplementary cement issues materials.
6
Our new course, Cement Chemistry and Sustainable Construction Materials, We'll introduce you using lectures and tutorials,
7
the basics of cement hydration and how to develop and characterize low carbon cement.
8
This course will be divided into major themes, the cement chemistry during the first four weeks,
9
then the last two weeks will focus on the use of X-ray diffraction for the analysis of low carbon cements.

Professor Scrivener, her team and Dr. Snellings, researcher at Vito, hope to find all you there.

About This Lesson

You're practicing English with "Cement Chemistry and Sustainable Cementitious Materials" using the Shadowing technique — a method originally developed for professional interpreter training.

Focus on sounding like the speaker — not just repeating words. With 15–30 minutes of daily practice, you'll build real-world speaking confidence.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
