Objective of the course – aims of the course unit:|
Following the knowledge obtained in the course Concrete Technology I, the knowledge is extended by information about new concrete types and the methods of their design, testing and conditions of use. The aim is to inform the students about up-to-date trends in concrete technology and about concrete with special properties such as high performance, high strength, self - compacting, light and dense concrete and further about concrete with increased resistance against aggressive media.
Objective of the course – learning outcomes and competences:|
The student would manage the goal of the subject by broadening the knowledge to new concrete types and their design methods, testing and application conditions, further to modern trends in concrete technology and also on concrete with special properties such as e.g. high-quality, high strength, self-compressing, light, heavy concrete and further concretes with increased endurance against aggressive surrounding.
Basic knowledge obtained in the course Concrete Technology I, especially concerning the properties of components for concrete manufacture, marking of concrete for normal and aggressive media, methods for designing concrete composition and for concrete testing, further information about lightweight building materials and processes of concrete degradation
