functionalizing and modifying the material property from the molecular or atomic scales as well. This fundamental understanding would facilitate the production of high-strength sustainable cement in the future. I believe that the fundamental computational
material models (at different scales) for cementitious materials is a promising field where further research would result in the development of more sustainable materials and/or better construction practices.
So far, we have discussed
multi-scale modelling with
respect to one material system
cement. There are plenty
of other examples in nature
where the principles are just
as relevant. For instance,
in biology, the hierarchical
structure of human bone
provides structural strength
and mobility to our bodies. The
deterioration in strength of a bone starts from
its very cellular composition and connectivity. In order to understand the maladies that affect our skeletal system, biologists and doctors need to look at the fundamental level. Another facet of this study is that it is interdisciplinary.
Understanding the behaviour of a material system on multiple scales warrants a working understanding of physics, chemistry and mechanics. Thus, the subject lets you explore wider and deeper and come up with innovative solutions for real-world problems. It is fascinating and relevant, and challenges your intellect and versatility. It promotes interdepartmental collaboration and teamwork. In short, it is an appealing area of research for the budding scientist in you.

It is estimated that every single person uses a tonne of concrete per year. For each tonne of concrete produced, the cement industry releases a tonne of CO2 into the atmosphere. Thus, cumulatively cement production is responsible for 7% of global CO2 emission. A solution to this problem is to develop more sustainable types of cement that do not have such a huge carbon footprint.
