During the last decades, alkali-activated cements and concretes have attracted strong interests all over the world due to their advantages of low energy cost, high strength and good durability compared to portland cements. A major incentive for further development of such cement is generated by the annual output of fly ashes from power plants and other by-product materials, which is so enormous that there is a constant need to find new uses for them. Approximately 49% of the utility wastes are simply landfilled, 41% are contained in surface impoundments, and about 10% are disposed of by discharging into old quarry operations.
Although much of the development of alkali-activated or alkaline cements has been based on activated slags, there is great potential for the utilization of other by-products, instead of using ordinary Portland cement.
Within the framework of the course, students get acquainted with the basics of the alkali-activated materials in civil engineering applications.

lectures and individual learning, review making and a short presentation by the PhD student.

Alkali-activated materials in Civil Engineering practice, examples (geotechnics, prefabrication, etc.)
