Fiber Reinforced Concrete (FRC), which is strengthening by short fibers, can improve not only mechanical properties but also durability due to reduced crack width by …
With the increasing of service life, reinforced concrete (RC) structures are affected by various factors, including carbonization, corrosion, freezing, and thawing in complex environments, reducing the seismic performance of the structures.
Fiber-reinforced polymer (FRP) composites have been widely used in civil engineering for either strengthening existing deteriorated reinforced concrete (RC) structures or constructing new structures.
Scientific Reports - Flexural capacity of eco-friendly reinforced concrete beams. ... Although it is recyclable, only 31.3% of the total amount of glass found is being recycled 4.

This research examines the impact of material selection on the carbon footprint of reinforced concrete buildings, aiming to reduce embodied carbon. For this purpose, two reinforced concrete buildings are designed for their embodied carbon to quantify their environmental impact.
About half of all concrete produced in Britain is reinforced and unlike structural steel the reinforcing steel made in the UK is made entirely from recycled steel, which itself can be recovered for reuse at the end of the building or structure's life. Although steel manufacture is an extremely energy-intensive business, the energy needed to ...
In order to investigate the corrosion mechanism of recycled reinforced concrete (RRC) under harsh environments, four recycled coarse aggregate (RCA) contents were selected, and saline soil was used as an electrolyte to perform electrified accelerated corrosion experiments. The relative dynamic elastic modulus and relative corrosion …
Reinforced concrete is everywhere. But unlike plain concrete, which can last for centuries, reinforced concrete can deteriorate in decades as the reinforcing bars succumb to rust.
An increasing number of applications use fiber-reinforced concrete instead. The tiny fibers are more difficult to separate from the concrete than steel. ... Solid-state recycling process becomes an effective and powerful methodology to realize the green state forming from recyclable waste to useful parts. The developed process can be …
Reinforced Concrete: Contrary to common perception, concrete with metal reinforcements (like steel bars) is also eligible for recycling. The metal is manually extracted during the recycling process and recycled separately.
However, knowing that concrete reinforced with commercially available steel or poly-propylene ... (PET) fibres were also tried but found to degrade after exposure to the alkalinity of concrete [19], [20]. Another recyclable polymer candidate for mass production of fibres is the high-density polyethylene (HDPE) whose physical and …
Yes, reinforced concrete can be recycled, although the process is more complex than recycling non-reinforced concrete. Reinforcing steel, such as rebar, must be removed from the concrete prior to crushing to prevent damage to the crushing equipment.

The construction industry now has many ways to recycle concrete. Learn about the uses, benefits, and equipment involved in reusing concrete.
A reinforced-concrete-structured sponge based on amino-terminated polydimethylsiloxane (PDMS) and carboxyl carbon nanotubes (CCNTs) is synthesized, without any templates or coatings. The covalent bonding of PDMS and CCNTs generate amide groups which provide considerable hydrogen bonds.

Would it be possible to continue to use concrete sustainably after demolition, eliminating its disposal as mere waste and overloading landfills?
Fiber-reinforced concrete reflects the upcoming trend to apply crack-resistant concrete more effectively. For example, PolyEthylene Terephthalate (PET) is a polyester polymer obtained from recyclable bottles; it has been widely used in the production of fibers for obtaining products based on the cement with improved properties.
Recycled concrete helps reduce construction's carbon footprint. Learn how this sustainable material is transforming the construction industry.
Fiber Reinforced Concrete (FRC) can improve not only mechanical properties but also durability due to reduced crack width. Previous researches only en…
In steel-reinforced concrete (SRC) structures, it is difficult to separate or recycle steel and concrete using traditional demolition methods, which create a large amount of construction waste. A green and recyclable technology for demolishing SRC structures by induction heating (IH) is proposed in this study.
Concrete is a major source of carbon emissions, but can it be reused or recycled? Find out how scientists are tackling this challenge in BBC Science Focus Magazine.
Comprehensive review on sustainable fiber reinforced concrete incorporating recycled textile waste ... for eco-efficient building application are also evaluated to draw the attention of ...
Yes, reinforced concrete can be recycled, although the process is more complex than recycling non-reinforced concrete. Reinforcing steel, such as rebar, must be removed …
The reason for recycling is the reduction of waste in order to protect nature against pollution, the increasing shortage of suitable dumping grounds, and to save …
E-bricks is a 4" x 8" x 2" concrete brick reinforced with solid wastes materials such as recyclable plastic and human hair. This study determined the feasibility of producing e-bricks, making it profitable and increasing market …
Reusing concrete can a good way to reduce construction costs while providing some benefits to the environment. Recycled concrete not only stays out of …
This paper reports on the efficiency of fabric-reinforced cementitious matrix (FRCM) in enhancing the flexural capacity and deformational characteristics of RC beams.
FIBRE CEMENT: A PERFECTLY RECYCLABLE BUILDING MATERIAL LUC VAN DER HEYDEN Redco N.V., Kuiermansstraat 1, 1880 Kapelle-op-den-Bos, Belgium ... fibre reinforced cement composites produced by means of the Hatschek technology, a technology described elsewhere (Van der ... cement (and eventually also of pozzolan), …
