The importance and necessity of chemistry in civil engineering: engineering is about design and the rendering of ideas into tangible items. In the design, the engineer must choose the materials for construction. Materials specification spans all the engineering disciplines and provides an opportunity to make chemistry relevant to engineering students. The theme of the semester is introducing material science on a chemical basis and understanding materials on an atomic scale.
The main objectives are: to acquire knowledge about chemical laws; material types; explore the causes of their changes, and recognise the difference between ideal and realistic material systems and microscopic and macroscopic behaviour. Outcomes: application of theoretical knowledge in engineering practice.

Lectures and individual learning,
During lectures, the understanding of the course material is supported by materials science examples.
