Teräsbetonista

Teräsbetonista, also known as reinforced concrete, is a composite material that uses concrete as a mass and steel reinforcing bars (rebar) or mesh to provide tensile strength. Concrete alone is strong in compression but weak in tension, meaning it can crack and break when pulled apart. Steel, on the other hand, is strong in tension and can withstand these pulling forces. By combining the two materials, teräsbetonista gains the advantages of both: the durability and compressive strength of concrete and the tensile strength of steel.

The process of creating teräsbetonista involves placing steel rebar within a formwork and then pouring liquid concrete around it. Once the concrete cures and hardens, the steel and concrete become bonded, forming a single structural unit. The steel rebar is typically coated to prevent corrosion, which can weaken the material over time. Common applications for teräsbetonista include buildings, bridges, dams, and other infrastructure projects where structural integrity and durability are essential. It is a widely used construction material globally due to its versatility, cost-effectiveness, and ability to be shaped into various forms. Its long lifespan and resistance to fire and natural disasters further contribute to its popularity in modern construction.
