1. Modern building material
Concrete is state-of-the-art because it and its components are continuously being refined. Through intelligent variation and modification of its constituents, concrete can repeatedly acquire new processing and performance properties.
2. Natural raw materials
Concrete consists primarily of sand, gravel, cement (made from limestone and clay), and water. These are all natural raw materials that contain no harmful substances.
3. Regional availability
The ingredients for concrete are practically available locally everywhere. This reduces transportation distances, lowers CO2 emissions, and makes supply independent of global supply chains.
4. Thermal efficiency
Concrete stores heat in winter and keeps rooms pleasantly cool in summer. This balancing effect enables consistent indoor climate with minimal energy requirements.
5. Part of the circular economy
At the end of its service life, concrete can be recycled and reused up to 100% – a closed-loop cycle for sustainable building.
6. Durability and resilience
Concrete buildings are robust and long-lasting, as the building material is highly resistant and increases in strength over time. It withstands weather, stress, and chemical influences.
7. Water impermeability
Concrete creates waterproof structures. This creates secure buildings for basements, underground garages, and dams that provide reliable protection against groundwater and surface water.
8. Fire resistance
Concrete does not burn or melt. In the event of fire, load-bearing capacity is maintained for extended periods, and neither smoke nor toxic gases are released. This protects people and significantly reduces material damage.
9. Sound protection
Concrete provides excellent sound insulation. Thanks to its high mass and density, sound waves are effectively absorbed and reflected. It reduces disruptive external noise and creates quiet interior spaces.
