Composite construction

Research team
The main goal of our team is the design and development of structures and structural elements from advanced cement-based materials with an emphasis on sustainable construction and circular economy.

These are mainly:
  • structures and structural elements from high-performance concrete (UHPC) unreinforced or reinforced with different types of fibers,
  • structural elements and structures from UHPC using textile (TRC) reinforcements,
  • structural elements from materials using waste materials from construction and demolition waste.

Our team deals with the optimization of cement composite recipes with regard to the structural use of the given material and the minimization of the environmental impact of the resulting structural element. At the same time, we focus on the design and optimization of structural elements for buildings and urban furniture.

From the point of view of the circular economy, we are dedicated to optimizing the demolition process to ensure the highest quality building materials suitable for recycling, which can further be used as input raw materials for new construction products.

All this in accordance with the principles of sustainable construction, so that our solution makes environmental and economic sense.

Main team activities

  • We develop materials and structures, including testing their physical, mechanical and rheological properties and durability:
    • high performance concretes (UHPC) unreinforced or reinforced with different types of fibers,
    • structural elements from UHPC using textile (TRC) reinforcements,
    • composite materials using waste raw materials (recycled construction and demolition waste, foam glass from recycled glass and others).
  • We carry out tests of the properties of aggregates for concrete, we also test the properties of fresh concrete and the properties of hardened concrete, mainly mechanical and deformation properties, as well as rheological properties and durability.
  • ​We have a room with a constant environment needed for the storage of cement composite samples.
