reinforced concrete recycling

Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually …

🕑 Reading time: 1 minute Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). This combination is made to use the compressive strength of concrete and tensile strength of steel at the same time, hence, work together to resist many types of loading. The term reinforced is used because the steel reinforces […]

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum …
