Language of instruction: The course will be given in Swedish
Concrete is the world's most widely used building material. Concrete structures are expected to perform well during a very long service-life without unplanned maintenance. Consequently, good utilization of resources requires a selection of materials and structural design concept by considering the complete life-cycle of the building or structure.
The course is meant to give the student a deeper understanding of how the properties of concrete depend on the composition of the material, the curing during construction and why and how the performance changes during its service-life. The course is also meant to give the student an ability to express performance criteria on concrete, select material components and composition and predict the performance during its service-life, in various applications.
Knowledge and understanding
For a passing grade the student must
After the course the student should
· well know and understand basic phenomena i fresh, hardening and hardened concrete
· understand the behaviour of concrete during production and normal use in various environments and during the entire servfice-life
· be able to put the environmental consequences of cement and concrete into a larger perspective
Competences and skills
For a passing grade the student must
After the course the student should
· have the ability to select concrete material and structural design concept in a life-cycle perspective and to assess the state of existing concrete structures
· be able to use the knowledge in advanced applications and to generalize it to completely new applications in buildings and structures.
Judgement and approach
For a passing grade the student must
After the course the student should have a clear picture of how to express performance criteria for concrete and how they can be fulfilled through selction of mix composition, production technology and maintenance measures, in a life-cycle perspective.
A central part is the performance over time and again processes in concrete and structures during production and normal use in various environments. The effects of environmental actions, required space for movements and crack risk evaluation are dealt with. Additionally, the selection of concrete constituents and composition fo fulfil given performance requirements is included.
In small groups do the students cast different concretes and study its properties regarding for example heat development, strength, self-dessication and chloride penetration. The experiments are presented both written and oraly.
