Concrete is the most used, man-made material in the world. It is comparatively durable and extremely formable. In the practice concrete is the only possible material for structures under the ground surface.
The concrete group at KTH is directed towards both materials and structural aspects of concrete construction. The area of research contains function, design, construction, performance and rehabilitation of concrete and masonry structures and buildings. Sprayed concrete (shotcrete) and technical applications for newly developed concrete materials and the effects of dynamic loading are also included. The research is directed towards large concrete structures, extremely loaded concrete structures and advanced concrete materials.
The division is currently active within the following research fields:
Studies of static and dynamic modes of operation in concrete structures, that optimally fulfils demands on load carrying capacity, robustness and other functions. Large and advanced concrete structures subjected to extreme loads is studied through finite element modelling and in situ measurements.
Properties related to material composition of reinforced and un-reinforced structures of concrete and other cement based materials are studied, with focus on efficiency and sustainability. State-of-the art laboratory methods are used together with advanced methods for numerical modelling and finite element analyses.
Research on structures for the hydropower industry studies functions and optimizations of technical systems and concrete structures for a sustainable and environmentally friendly energy production. Advanced methods for in situ observations and measurements together with structural analysis are used.
The performance and properties of shotcrete are studied in laboratory, in situ and through numerical modelling. The vibration resistance of young and hardened shotcrete on rock is one specialization.
Properties of concrete structures for e.g. shelters, barriers and energy absorbing systems are studied through numerical modelling and laboratory testing. Load cases of interest are explosions, air blasts, weapon loads, impacts and earthquakes.
Research directed towards studies on production, construction, design and function of infrastructure within civil engineering and buildings. Special focus is on methods for producing climate-smart and sustainable concrete structures.
