Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...

Ways to Recycle and Reuse Concrete

Concrete always contains a certain amount of moisture that, when exposed to high temperatures, evaporates and pushes the material outwards, causing explosive fractures. When propylene fibers are added, though, they can melt leaving micro-grooves that channel the steam. Most of the construction concrete has been reinforced with steel.

Removing plastic from landfills does not solve the solid waste problem entirely. Plastic products are difficult to recycle because, unlike aluminum or glass, the plastics used in food packaging cannot be reused for the same purpose. Among the commonly used plastic resins, polyethylene terephthalate (PET) has been widely adopted by the packaging industry.

Utilization of Recycled Carpet Waste Fibers for ...

Abstract The use of recycled fibers from textile waste for concrete and soil reinforcement is a very attractive approach, with such benefits as performance enhancement, low-cost raw materials, and reduced needs for landfilling. This article discusses the general advantages of fiber reinforcement and reviews some studies on the use of carpet waste fibers for concrete and soil reinforcement.

Reinforced concrete - Wikipedia

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