Concrete Technology. Concrete is a basic building material needed for many Civil Engineering projects. There is a great deal to this subject, from the types of different concrete mixtures, to curing concrete, methods of recycling it and more.
1. Introduction. Recycling of concrete is one of the important issues for the establishment of sustainable society, and a technology to produce recycle aggregate has been developed in concrete engineering.
Concrete Recycling Concrete recycling entails breaking, removing, and crushing concrete into a material of a specified size and quality—not unlike the processes of crushing materials. Demolished sidewalks, building columns, or foundations are broken up and compiled.

Little has been published about the demolition of post-tensioned concrete but there is enough such concrete now in service to become a problem for demolition contractors. When a demolition sequence is being planned it is important to have a knowledge of the erection procedure and a set of the as
The National Concrete Pavement Technology Center (CP Tech Center) is a national hub for concrete pavement research and technology transfer. The CP Tech Center was founded in 2000 and has been instrumental in developing and helping to advance the nation's strategic plan for concrete pavement research, the CP Road Map.
This contribution by reinforced concrete in providing recycled materials is recognized by LEED. More than 7 million tons of scrap steel is recycled into reinforcing bars every year, virtually the entire feedstock. This recycling avoids a massive energy expenditure — one ton of steel reinforcing bars would otherwise require about 2,500 pounds of ore, 1,400 pounds of coal, and 120 pounds of ...
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.
Concrete recycling. Jump to navigation Jump to search. Concrete from a building being sent to a portable crusher. This is the first step to recycling concrete. When structures made of concrete are demolished or renovated, concrete recycling is an increasingly common method of utilizing the rubble. Concrete was once routinely ...
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 produce one tonne of reinforcing steel is as low as ...

Several articles in Reinforced Plastics have advised us of the development of pyrolysis based carbon fibre recycling processes and these are now commercially available in several places since the launch of Milled Carbon (now ELG Carbon Fibre) in the West Midlands, UK.
Recycling concrete from demolition project can result in considerable savings since it saves the costs of transporting concrete to the landfill (as much as $ .25 per ton/mile), and eliminates the cost of disposal (as high as $100 per ton).

Home / Concrete Technology / RECYCLING OF WASTE CONCRETE Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates.
Both aggregate recycling sites will be closed for the winter season, effective November 30, 2018. The sites will reopen on April 1, 2019. The sites will reopen on April 1, 2019. Aggregate waste (asphalt and concrete) is still accepted at the Edmonton Waste Management Centre.

Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces transportation costs because concrete can often be recycled in areas near the demolition or construction site.

Reinforced concrete, Concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.
