Staalconcreet

Staalconcreet is a term used to describe a steel–concrete composite material in construction, where structural steel elements are integrated with concrete to form a single, interacting system. The combination leverages the compressive strength of concrete and the tensile strength and ductility of steel, enabling efficient resistance to a range of loads.

The material typically consists of a concrete matrix with embedded steel reinforcement, such as bars or mesh, and may include additional steel components such as plates or hollow sections for enhanced stiffness. In many applications, composite action is achieved through a strong bond between steel and concrete, often aided by anchorage, cast-in connectors, or mechanical fasteners. Steel fibers or embedded steel sections can also be used to tailor performance.

Design and construction consider the bond between steel and concrete, differential thermal expansion, and potential durability issues. Proper detailing of reinforcement, concrete cover, and jointing is essential to prevent premature cracking or corrosion. Fire resistance and long-term durability depend on concrete quality, protective coatings, and environmental exposure. In corrosive environments, corrosion protection strategies for the steel elements are critical.

Common applications include building frames, floors, bridges, and parking structures where high load capacity and ductility are beneficial. Design standards and guidelines for staalconcreet align with national and international codes for reinforced concrete and steel-concrete composites, addressing aspects such as load combinations, detailing, and durability requirements.
