Резюме

Every day, we see concrete used all around us – to build our houses, offices, schools, bridges, and infrastructure. But few people actually understand what gives concrete its strength, resistance, and utility.

The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering.

You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers. You’ll learn to test your samples in isocalorimetry in order to track the hydration and to prepare and observe samples by scanning electron microscopy. In the last two weeks of the course, you will also learn how X-ray diffraction works and how to apply it to cements.

Because the course is designed for beginning students, it’s not necessary to have a cement background, however a bachelor degree in Materials Science or knowledge in chemistry, physics and crystallography will help. This course starts with basics of cement, and progressively covers the latest advances in the understanding of cement hydration. This course lasts 6 weeks, during which you can take theoretical courses and tutorials to test the cement in the laboratory.

  • Understanding of the hydration of cement
  • The science and utility behind Supplementary Cementitious Materials in concrete technology
  • Best practices (via tutorials) for testing samples through X-Rays diffractometry, Scanning Electronic Microscopy and Isothermal calorimetry

Специальные требования

This course will go into the details of the mechanisms of cement hydration. The most useful techniques for the characterization of cementitious materials will also be quite deeply explained.

In order to assimilate all this information, it is recommended for the attendees to have a solid background in chemistry, physics and crystallography, or a bachelor in Materials Science.

Платформа

Edx

EdX est une plateforme d'apprentissage en ligne (dite FLOT ou MOOC). Elle héberge et met gratuitement à disposition des cours en ligne de niveau universitaire à travers le monde entier. Elle mène également des recherches sur l'apprentissage en ligne et la façon dont les utilisateurs utilisent celle-ci. Elle est à but non lucratif et la plateforme utilise un logiciel open source.

EdX a été fondée par le Massachusetts Institute of Technology et par l'université Harvard en mai 2012. En 2014, environ 50 écoles, associations et organisations internationales offrent ou projettent d'offrir des cours sur EdX. En juillet 2014, elle avait plus de 2,5 millions d'utilisateurs suivant plus de 200 cours en ligne.

Les deux universités américaines qui financent la plateforme ont investi 60 millions USD dans son développement. La plateforme France Université Numérique utilise la technologie openedX, supportée par Google.
